CTS-V Low-Gloss Matte Paint Finish

Transcription

1 February 2013, Volume 15, No. 2 CTS-V Low-Gloss Matte Paint Finish A limited production run of 2013 CTS-V Coupes will feature a new Silver Frost low-gloss matte paint finish (RPO GHD). This is the first GM regular production vehicle to offer a matte paint finish. The matte finish adds a metallic appearance to the vehicle. Unlike typical gloss paints that employ a clearcoat that reflects light and leave a bright sheen, the matte finish uses a distinct clearcoat applied over the silver basecoat that diffuses and absorbs light to create a unique flat finish. The matte finish requires special care requirements during Pre-Deliver Inspection (PDI) as well as by customers in order to maintain its unique appearance. Dealerships that receive a CTS-V with the matte finish are required to have a sales and service point of contact to ensure the proper paint care requirements are followed. A Silver Frost delivery packet will be shipped to the dealership that includes instructions for the PDI process, a letter from Cadillac to be presented at delivery, paint care instructions, and a customer care acknowledgement form. In addition, a label with paint care instructions will be installed on the driver s window. The paint care guidelines must be reviewed with customers at the time of delivery. Care and Handling CTS-V models with this special lowgloss paint finish are protected with a temporary peelable film. To remove the film, peel it off while rinsing the vehicle continued on page 2 TECHLINEnews Tech 2 Final Update In December 2012, GM North America released the final diagnostic software update for the Tech 2. The data accessed via TIS2Web as a download is used for the Tech 2 scan tool as well as the Tech2Win PC-based application. Although this update will be the final version for the Tech 2 scan tool, future Tech2Win application updates may be available. The Tech 2 scan tool or Tech2Win application can be used for diagnosing 2013 model year and earlier GM vehicles. The Global Diagnostic System 2 (GDS 2) will be the only diagnostic tool for diagnosing vehicles for 2014 model year and beyond authored by GM. If an issue is identified with the GM- authored Tech 2 software after December 2012, the issue will be evaluated and a decision will be made whether to author new Tech 2 software or to author the vehicle(s) in question in GDS 2. If the fix is implemented in the Tech 2 software, there will be a special, unscheduled release of the software through TIS2Web. Although the GM software updates for the Tech 2 will conclude, GM will continue to support the Tech 2 hardware. If you have any questions regarding Tech 2 support, contact the Techline Customer Support Center (TCSC) at (English) or (French). Thanks to Chris Henley Contents Customer Care and Aftersales

2 Low-Gloss Matte Paint Finish continued from page 1 with cold water. The best exterior surface removal temperature for the film is 70 F (20 C). TIP: To maintain appearance of the matte finish, do not rub the paint surface, only wipe lightly. Rubbing the finish will create bright spots and an uneven appearance. Refer to the PI in the Service Information and the updated PDI form before washing or servicing vehicles with the matte finish. Liquid car wash soap and water as well as mild, non-abrasive bug/tar removers are the only cleaning materials that should be used to clean the Silver Frost low-gloss matte paint. For these vehicles, DO NOT: Apply add-on paint coatings or sealant protective coatings Wax or polish the low-gloss finish Finesse polish or rub the paint surface with any type of cleaner, glaze, wax or rubbing compound Use additional clearcoat sealants in automatic car washes Normal hand-washing or power-washing does not impact the low-gloss finish of the paint. When washing, wipe in a light forward and backward motion; avoid circular motions, which can alter the finish. Do not wipe the surface with a dry towel. Use a clean, damp chamois or microfiber towel to dry the vehicle and avoid water spots. Remind owners that touch-free car washes are the only safe automatic car washes to use. Commercial car washes with any types of brushes are not recommended. Also, do not use a liquid wax in any car wash system. Immediately remove foreign materials such as tar, tree sap, bugs and salt, from the paint surface. To remove the adhesive from shipping labels without forceful rubbing, use a mild solvent-based adhesive remover. Scratches, rub marks and other damage to the painted surface can be touched up similar to other types of paint, but any paint surface imperfection that would normally be repaired by polishing on high-gloss paint must not be attempted on the matte finish. TIP: If the matte finish is altered, the affected panels will have to be repainted to return it to the intended low-gloss appearance. Thanks to Jean Hart and Gary Kirrkamm Poor Remote Keyless Entry Transmitter Range The Remote Keyless Entry (RKE) transmitter range may be very poor on some 2012 LaCrosse (after build date 9/13/11), 2012 Regal (after build date 10/5/11), 2012 Verano, 2012 SRX (after build date 8/26/11), 2012 Cruze (after build date 9/26/11), and 2012 Volt (after build date 9/9/11) models equipped with Passive Entry Passive Start (PEPS) (RPO BTM). The transmitter may have to be very close to the vehicle before it operates. In addition, the Tire Pressure Monitor (TPM) system may display dashes for the rear tire pressure readings. DTCs C0750 (Left Front Tire Pressure Sensor), C0755 (Right Front Tire Pressure Sensor), C0760 (Left Rear Tire Pressure Sensor) or C0765 (Right Rear Tire Pressure Sensor) may be set. Verify the RKE transmitter range by pacing off approximately 100 ft. (30 m) diagonally at all four corners of the vehicle. If the RKE range is acceptable, follow the TPM Diagnostics in the appropriate Service Information. If the RKE range is poor or if a TPM DTC is present, replace the Remote Control Door Lock Receiver (RCDLR) module. Thanks to Gordon Baillod Horn Chirps When Entering Vehicle The horn may chirp rapidly three times occasionally when entering a 2012 Lacrosse equipped with Keyless Start (RPO BTM). This condition may occur if the ignition is turned to the Off position while any door remains open. The next time one of the vehicle s doors is opened with the key fob within range, the three rapid horn chirps may occur. Update the BCM with the latest calibration. Refer to the Body Control Module Programming and Setup procedure in the appropriate Service Information for further details. Thanks to David Roat 2 February 2013

3 Camaro Hot Wheels Edition Front Splitter Installation Put the new 2013 Camaro Hot Wheels Edition on an orange race track and it would be right at home. It s the first full-size, production Hot Wheels car built by any manufacturer and its appearance mirrors that of the Custom Camaro 1:64-scale toy released in 1968, one of the original 16 Hot Wheels issued and one of the most valuable Hot Wheels among collectors. The Camaro Hot Wheels Edition (RPO HWS) is available in coupe and convertible models (V6 and V8) and features: Kinetic Blue paint ZL1 rear spoiler (coupe models) ZL1 front upper grille Ground effects package, including front splitter and rocker treatment Black 21-inch wheels with red outline stripe Two-tone matte hood graphic, rear taillight panel blackout graphic and fender flame graphics Front Splitter Installation Due to the low profile of the Camaro Hot Wheels Edition and the possibility of damage during transport, the front splitter is not installed during assembly. The splitter is delivered to the dealership in the interior of the car and must be installed during Pre-Delivery Inspection (PDI) just as with the Camaro Dusk (RPO CCS) and Camaro 1LE (RPO 1LE) models. TIP: The labor code for splitter installation is Z6998 PDI - Dealer Installed Factory Invoiced Options. Do not submit a regular warranty claim for splitter installation. The splitter package includes the splitter, three brackets, fasteners and a template. The fascia is not removed from the vehicle during splitter installation. The splitter is supported by the three brackets and secured at the rear and front of the splitter from below the vehicle. Installation instructions are included with the splitter and also are in the Service Information. Thanks to Brad Thacher and Jack Pantaleo ATS Electronic Parking Brake Indicator Some 2013 ATS models feature an optional electronic parking brake (RPO J77). On vehicles built before December 10, 2012, the parking brake indicator on the instrument cluster may illuminate while driving and without application of the parking brake. The electronic parking brake assembly has an internal force sensor monitoring the force applied to the parking brake cable. If this sensor is too sensitive, it may command the parking brake indicator to illuminate without parking brake application. To correct this condition, program the Electronic Parking Brake Control Module with the latest calibrations available. Drivers of all ATS models equipped with the electronic parking brake also may notice that after setting the parking brake and turning off the ignition the parking brake indicator on the instrument cluster remains illuminated. This is normal operation and does not require any repair or replacement of parts. When the parking brake is applied, the indicator may remain illuminated as little as 20 seconds or as long as the serial data bus remains active. Thanks to Jeremy Richardson The electronic parking brake switch is located on the left side of the instrument panel. February

4 Multiple Conditions Caused by Aftermarket Devices Plugged into the Data Link Connector For everything from saving on automobile insurance to connecting aftermarket cruise control, there are now a number of devices that owners plug into the Data Link Connector (DLC), or Assembly Line Diagnostic Link (ALDL). However, any unauthorized device connected to the DLC may cause a variety of hard-todiagnose conditions. Many of the problems caused by devices connected to the DLC are communication issues on the High Speed Controller Area Network (HSCAN) bus. An additional issue with diagnosing these conditions is that many times the device itself may be removed by customers when their vehicle is brought in for service. Many possible problems are caused by an open connection on the HSCAN bus. For example, if the device only makes connection with one CAN +, it will cause bus errors and strange control module behavior. Known Symptoms The various issues described by customers with their vehicles are often related to high- or low-speed data bus traffic. The conditions can be extremely varied, but some known issues are: Radio will not turn off after turning off the vehicle Bus or LAN traffic stays active, leading to a discharged battery Problems reprogramming control modules either because of interference or the device will not allow the bus to power down Interference with OnStar s ability to provide diagnostic data Engine and transmission performance issues with the Check Engine light on Intermittent stalling Reduced power DIC messages and DTCs StabiliTrak DIC messages and DTCs DTC C0561 (System Disabled Information Stored Invalid Data) in the Electronic Brake Control Module (EBCM) leading to a traction control issue No High Speed LAN communication along with various DTC communication U-codes Transmission will not shift for one key cycle (TCM in default mode) Instrument cluster gauges erratic or flickering Service Engine Soon or Check Engine MIL illuminated and numerous DTC communication codes such as U0100 (Lost Communication With Engine Control Module), U0101 (Lost Communication With Transmission Control Module), U186B (Electronic Brake Control Module Lost Communication with Transmission Control Module) and U1862. Diesel power-up devices resulting in no power in 4WD Low range Service Tire Pressure Monitor System MIL illuminated; cannot relearn the Tire Pressure Monitor System Hybrid issues regarding reduced propulsion power DIC messages and service high voltage charging system DIC messages Diagnosis TIP: The Diagnostic System Check Vehicle (the starting point for any diagnostic procedure) in the Service Information calls out that there should not be any aftermarket devices connected or installed that affect the operation of the system. Additional information under Checking Aftermarket Accessories explains how to check for aftermarket accessories. The Diagnostic System Check Instructions link at the top of the Diagnostic System Check Vehicle procedure also provides further information about aftermarket accessories and their possible negative effect on the vehicle. During diagnosis, if nothing else can be identified as the root cause of the condition, check for a device plugged into the DLC. If a device is available, attempt to duplicate the condition. Remove the device to determine if the condition is eliminated. If confirmed, inform the customer of the issue and that it will be necessary to work with the supplier of the device for further resolution. If the condition is not eliminated, continue with the diagnostics in the appropriate Service Information. If any parts appear to have been damaged by the device or the installation of the device, document on the repair order what was identified on the vehicle. This would not be covered under the New Vehicle Limited Warranty. Possible Devices Aftermarket device with a DLC connector Aftermarket cruise control interface at the DLC Insurance monitoring device (styles of these devices will vary) Fleet tracking interface at the DLC Connected devices may be used for such things as tracking and/ or maintenance interval scheduling (more common on fleet and rental vehicles), insurance monitoring that automatically keeps track of the vehicle s driving record, aftermarket cruise control, police speed checking (RADAR or LIDAR) and other aftermarket components. continued on page 5 4 February 2013

5 Share Additional Customer Information in PIs and Bulletins GM dealerships and GM customers, additional customer information will now be included in certain Preliminary Information (PI) and/or service bulletins. This information will be contained in a separate section, when applicable, titled Customer Information. Not all PIs/bulletins will contain additional customer information. Dealership service personnel can use the information to: Communicate a normal operating characteristic of the vehicle (that may not be commonly understood) Communicate that GM is aware of an issue and evaluating the condition along with potential solutions Following are a few examples of information that might be included in the new Customer Information section. Example 1 Normal Operation Customer Information: Please communicate to the customer this condition is a normal operating characteristic of their vehicle. It will not impact the designed performance or reliability of the vehicle. Please share this information with the customer, including a copy of this message. Example 2 Working on a Solution Customer Information: Please communicate to the customer that we apologize for this inconvenience and that General Motors is working on a solution for this concern. Once a solution is available, this PI will be updated with additional details allowing dealership personnel to contact the customer to schedule a service appointment and repair the vehicle. Example 3 Evaluating the Condition Customer Information: Please communicate to the customer that we apologize for this inconvenience and that General Motors is evaluating this concern and potential solutions. This PI will be updated with additional details as they become available. Call TAC For certain PIs/bulletins that include Example 2 or Example 3 in the Customer Information section, dealership personnel are asked to call the GM Technical Assistance Center (TAC) to set up a TAC case on each customer complaint they receive. For each case, the TAC agent will record the VIN and tag the case so that when a fix is identified, the dealership will be notified on each of the VINs involved so that they may contact the customer for further evaluation and a possible repair. All service consultants are encouraged to use this new information in PIs and service bulletins to improve their communication with customers. Thanks to Tod Stump PI/Bulletin customer information Multiple Conditions Caused by Aftermarket Devices continued from page 4 Sometimes, an aftermarket device has another DLC on it and the rest of the harness is tucked out of sight underneath the instrument panel, making it not completely obvious to the technician while still allowing diagnostic tools to be used. OnStar Certain aftermarket devices connected to the DLC may interfere with OnStar s ability to perform a diagnostic probe when requested (via a blue button call) by a subscriber. These devices also prohibit the ability to gather diagnostic and tire pressure data for a subscriber s scheduled OnStar Vehicle Diagnostic (OVD) . These aftermarket devices use the vehicle s serial data bus to perform data requests and/or information gathering. When these devices are requesting data, OnStar is designed not to interfere with any data request being made by these devices as required by OBD II regulations. When performing a diagnostic check for an unsuccessful or incomplete OnStar diagnostic probe, or for concerns regarding completeness of the OVD , verify that an aftermarket device was not present at the time of the requested probe. If an aftermarket device is interfering (including a scan tool of any type), the OVD will consistently display a yellow indication in the diagnostics section for all vehicle systems except the OnStar System, and the tire pressure data (not available on all vehicles) will not be displayed (i.e. the section is collapsed). Refer to Bulletin # A for additional information on OnStar Diagnostic Services. Thanks to B.J. Lackey February

6 Wide Range Air/Fuel Sensors Since wideband oxygen (O2) sensors, or Wide Range Air/Fuel (WRAF) sensors, were introduced in the late-1990s, they have become critical parts of the modern engine management system that is required to meet ever lower emission targets and higher fuel economy goals all without compromising engine performance. WRAF sensors can gauge how much oxygen is in the exhaust stream, which enables the Engine Control Module (ECM) to precisely gauge combustion mixtures and effectively manage the combustion process. Enhanced Accuracy WRAF sensors are different from conventional switching oxygen sensors. WRAF sensors incorporate both an oxygen-pumping cell and the more familiar conventional switching oxygen-sensing cell. WRAF sensors are a planar type (the flat plane shape of the sensing element) and consist of an oxygen sensing cell, an oxygen pumping cell and a heating element. The wiring harness of a WRAF sensor typically has five or six wires. As with all oxygen sensors, the WRAF sensor measures the amount of oxygen in the exhaust system but measures a wider range more quickly and more accurately. This allows the fuel control system to stay closed-loop during more conditions than a conventional switching-style oxygen sensor, including: High power and engine protection modes where enrichment is necessary During light-off or after-start modes, reducing cold start emissions Depending on the application, the fuel control system status will still go into open-loop during some operating conditions (e.g., deceleration, faulted states). Sensor Design The WRAF sensor heater is pulse-width-modulated and is used to keep the sensor around 800 C, with an operating range of 600 C to 950 C. Temperatures over 950 C can damage the sensor. A trim resistor is incorporated into the WRAF sensor connector to calibrate the sensor during assembly. The trim resistor is either laser-etched or added into the connector at the end of the manufacturer s assembly line to change its resistance and output current. The overall effect shifts the sensor output response to the appropriate level specified for the application. During engine operation, the exhaust gas travels through the diffusion barrier into the diffusion gap between the sensing cell and the pumping cell. The ECM will keep the diffusion gap mixture at lambda value of 1 (14.7:1 air-fuel ratio) by pumping oxygen ions into or out of this gap using the pumping cell. The ECM determines how much pumping current is needed by monitoring the oxygen sensor sensing cell value. A lambda value of 1 corresponds to a conventional sensor reading of 450mV. Therefore, the required pumping current is an indicator of how rich or lean the exhaust gas is at any particular time. Compared to a conventional switching sensor, using a WRAF sensor informs the ECM of exactly how rich or lean the air-fuel ratio is. A conventional switching oxygen sensor will only indicate if the air-fuel ratio is lean or rich. Scan Tool Parameters The scan tool parameter associated with the WRAF sensor is different than the parameter associated with a conventional sensor. For a WRAF sensor, the scan tool displays O2 sensor readings in lambda. Lambda equals the actual air-fuel ratio divided by the stoichiometric air-fuel ratio. A lambda value greater than 1.0 indicates a lean condition and a lambda value less than 1.0 indicates a rich condition. If the ECM detects an excessively lean or rich condition, the ECM will set a fuel trim Diagnostic Trouble Code (DTC). Thanks to Eric Hall Lean condition The scan tool lambda value indicates a lean or rich condition. Power Steering Control Module Programming Upon starting the engine on some 2013 ATS models, there may a loss of power steering assist and the Driver Information Center may display a Service Power Steering message. This condition only occurs immediately following an engine start right after turning off the ignition, combined with a low voltage condition such as that of a low battery. It may be difficult to reproduce this condition. If the Ignition is turned off and 15 seconds passes (enough time for the vehicle control modules to go to sleep) before the engine is restarted, the condition will not be present. The Power Steering Control Module will have a stored DTC C0545 Symptom Code 00. (Steering Wheel Torque Sensor Malfunction). Program the Power Steering Control Module with the latest calibrations available in TIS2Web. Be sure to follow the SPS guidelines for programming and configuration of the control module.

8 Inoperative Power Door Locks and Windows The power door locks and/or windows may be inoperative on some 2013 Silverado and Sierra models without Memory Seats (RPO AN3) or Power Folding Mirrors (RPO DL3). This condition may be caused by poor terminal tension at connectors X500 (1), X501 (2), and/or X600 (3). Connector X500 Connector X501 Connector X600 Using the gray Diagnostic Test Probe J A, test each of the terminals for proper tension and repair/replace as necessary. Thanks to James Will Electronic Climate Control HVAC Control Module Programming On some 2013 Malibus, there may be an intermittent condition where unwanted full heat is delivered from the vents when the vehicle is started and/or the driver s or passenger s heated seat may not activate when the respective switch is pressed. Reprogram the Electronic Climate Control (ECC) HVAC Control Module. Using SPS, select ECC Remote Heater and Air Conditioning Control Module Programming. Once completed, select: ECC Remote Heater and Air Conditioning Control Module Setup to set up the module after programming. Evaluate performance of both systems to validate the repair. Thanks to Christopher Crumb HVAC Mode/ Temperature Malfunctions The HVAC mode or temperature functions on the 2013 ATS may not respond correctly, possibly getting stuck in the Defrost or Max Heat mode, or providing only hot or cold air flow. If any DTCs are set in the Electronic Climate Control Module, follow the appropriate Service Information. If DTCs are not present, perform the Actuator Recalibration procedure outlined in the Service Information. Thanks to Jeremy Richardson and Steve Jacob Intermittent No Heat Condition in Electric Mode On some 2013 Volts, there may be an intermittent no heat condition when in electric mode. The no heat condition will not be present when in charge sustaining mode (engine on). This condition is very infrequent and usually goes away after powering down the vehicle and letting it sit for 4-5 minutes with the ignition off. If the no heat condition is present all the time, follow normal diagnostic procedures in the appropriate Service Information. Do not replace any HVAC components, including any coolant pumps or valves. Only if the condition is intermittent, update the K33 HVAC Control Module with the latest calibration in TIS2Web.
