Service Workbench Maintenance Menus Now Available to Technicians Anytime

December 2015, Volume 17, No. 23 Service Workbench Maintenance Menus Now Available to Technicians Anytime Service technicians now have the ability to view Maintenance Menus in Service Workbench for a vehicle in their service bay at any time, either through the Service Visit Summary page or other tools in Service Workbench. Previously, the Maintenance Menus could only be seen by technicians if the service consultant had first initiated the menu in the Service Workbench system. Now, a technician can view a menu by: First accessing the Service Visit Summary Link from Global Connect continued on page 2 Service Workbench Maintenance Menu Techline News Quick Learn Process for Additional Keys A new quick-learn process has been developed for programming additional keys without using the Service System (SPS) for keyed vehicles in the U.S. and Canada. The Adding Keys quick-learn procedure (Service Information ID: 3273485) does not erase any keys prior to programming. The procedure will simply program the key into the next available slot. The new procedure does not apply to vehicles equipped with a keyless access system (pushbutton start). continued on page 2 CONTENTS Service Workbench Maintenance Menus.. 1 Quick Learn Process for Additional Keys....1 New My Shortcuts Panel in GlobalConnect....3 Dashes on Outside Air Temperature Display....3 TAC Implements New Tools for a Better Caller Experience...3 Service Theft Deterrent Message....4 Inoperative Radio with DTC U0186....4 Chime Volume Too Loud....4 Bulletin Review...5 Emerging Issues..................... 6 Customer Care and Aftersales

Service Workbench Maintenance Menus Now Available to Technicians Anytime continued from page 1 Once on the Service Vehicle Summary page, there are several ways to access the menus: Selecting the New Menu button on the top right of the Service Visit Summary page. Using the Start Menu link in the Menu Status column if a new service visit has already been started. Using the Maintenance Menu tab at the top left of another tool currently being used (such as the Dashboard or Multipoint Inspection) Using the New Menu button allows the technician to begin a new menu using either a VIN or by selecting a year, make, and model from the dropdown menus provided. Select the New Menu button on the Service Visit Summary page. All of these methods are now available to the technician regardless of the service consultant starting the Menu first. However, technicians will not be able to save the menu in the system as a new menu. The service consultant must save the menu in the system. Thanks to Robert Thwing Service Visit Summary application in Service Workbench Start a new menu with a VIN or model information. Techline News Quick Learn Process for Additional Keys continued from page 1 If a new key is being learned to a vehicle to replace a damaged, inoperative, or stolen key, the Replacing Keys procedure in the Service Information must be used, which will erase all the known keys from the vehicle. This ensures that the old key cannot be used to access or start the vehicle after programming. Adding Keys The quick-learn procedure requires that one learned key be available (U.S.). In Canada, two learned keys must be available. Eight keys may be learned to one vehicle. The keys to be learned must duplicate the mechanical cut of the current key. 1. With a previously learned key, turn the ignition on. 2. Turn off the ignition and remove the key. In Canada, repeat the ignition on/off procedure with the second previously learned key. 3. Within 10 seconds of turning off the ignition, insert the new key to be learned and turn the key to the On/Run position. Do not turn the key to the Crank/ Start position. Keep the key in the On/ Run position for five seconds until the security theft warning lamp on the instrument cluster turns off, indicating the vehicle has learned the new key. Repeat this step for any additional keys. TIP: The 10 second time constraint must be met in order for programming to be successful. Be sure to keep other keys and transmitters at least 12 inches (30 cm) from the ignition cylinder while learning a key. 4. Verify each key operates properly. Remove the key from the ignition and wait 30 seconds. Insert the key into the ignition and start the vehicle. If the key doesn t work properly, repeat the quick-learn process, paying close attention to the time limits. Thanks to Theon Tinker and Peter Joslyn 2 December 2015

New My Shortcuts Panel in GlobalConnect The My Shortcuts tab at the top of the new GlobalConnect home page has been updated and moved to the top-right of the page, making it easier for users to access their frequently used apps without extra clicks. Plus, the list of shortcuts can now be customized so the apps used most are at the top of the list. Sorting Shortcuts Creating a shortcut for an app from the App Center is still done just like before. Up to 15 shortcuts will appear in the new My Shortcuts panel. To manage the apps, click the menu icon ( burger button} and choose your top 15 favorites for the My Shortcuts panel. Only the apps added as your shortcuts appear in the list. Use the Add to My Shortcuts button in the App Center to add a new shortcut. Sort the order of the shortcuts by clicking the Sort Apps button. Each app shortcut will be numbered and have a dotted line it. Click and drag an app shortcut to where you want it to appear in the list by numerical order. Any of the shortcuts can be moved. Click the Save button to save the new list order. The new order will appear in the My Shortcuts panel. Thanks to Lisa Scott Click and drag a shortcut to change the order of your My Shortcuts list. Dashes on Outside Air Temperature Display The outside air temperature display on some 2013-2015 ATS, SRX, XTS and 2014-2015 CTS Sedan (VIN A) models may intermittently show dashes instead of a numeric value on the Cadillac CUE touch screen. This can occur whenever a battery is disconnected or other loss of battery power occurs. Once system voltage has been restored, the BCM must see the Engine Run flag once before it sends temperature data to the display. This is a normal operation of the Cadillac CUE system. When the battery is disconnected and reconnected for service repairs, be sure to perform the following steps prior to returning the vehicle to the customer: 1. Start the engine. 2. Cycle the ignition Off. 3. Restart the engine. 4. Confirm that the outside temperature is now displayed. Thanks to David Antal TAC Implements New Tools for a Better Caller Experience The goal of the GM Technical Assistance Center (TAC) is to ensure that every TAC consultant provides top quality service each time a technician calls for diagnostic help with a vehicle. With this goal in mind, TAC (in the U.S.) has rolled out several new tools and procedures this year. TAC consultants now have a new tracking system for cases, a new robust knowledge management tool, and an updated phone system. Each of these tools help consultants quickly provide the information technicians need to make diagnostic and repair decisions. A special thank you goes out to callers for their patience while these tools were being implemented. In addition, TAC has redesigned the caller experience by: Improving Consultant Utilization Reducing the average amount of time spent on each call through performance management, getting callers the information they need quickly and efficiently Improving Schedule Efficiency Optimizing consultants schedules to ensure a high level of service and convenience for technicians Reducing Repeat Calls Reducing the number of times technicians make repeat calls that may be needed for complicated vehicle issues Reducing After-Call Work Improving the effectiveness of consultants after the call using the Performance Management database also increases consultants availability The feedback of callers provided through the TAC surveys and reviews helps identify areas where continued improvements are needed as well as how recently implemented changes are working. At the end of November, TAC s overall customer satisfaction rate for the year came in at 91%, with an 85% first call resolution closure rate. Helping to achieve those ratings were the more than 11,000 technical training hours consultants completed during 2015. Another accomplishment has been an improved service level with 70% of calls answered within 60 seconds for the last three months. Looking forward to 2016, the TAC will be implementing a new survey for technicians with a new look. We would like to thank technicians in advance for their continued participation. The feedback technicians provide is key to the success of the TAC. 2016 will also bring an introduction to a slimmed down phone prompt system, which should reduce the number of prompts needed to get to a TAC consultant, and enhanced training programs for consultants. The TAC also is sharing the information generated by technicians calls. In the last year, more than 800 PI s have been published in the Service Information for dealership technicians. The success of the TAC depends on our relationship with everyone in the dealership service department. The improvements made over the past year are designed to help provide an outstanding customer experience. Thanks to Elizabeth Belland December 2015 3

Inspect the connections at the immobilizer control module and ensure there is enough slack in the harness with the steering column extended. In addition, verify there are no proximity passes or fobs (except the GM Remote Keyless Entry transmitter) on the key ring. If other fobs or passes are present, they should be removed. Reprogram the BCM with most recent calibrations found in TIS2Web. Thanks to Ken Cole Inoperative Radio with DTC U0186 Some 2016 Volt models equipped with the premium speaker system and amplifier (RPO UQA) may have a condition where the radio and/or audio is inoperative or intermittently inoperative. DTC U0186 (Lost Communication with Speaker Amplifier Module) may be set and there may not be any communication with the amplifier. Do not replace the amplifier for this condition. Inspect the amplifier connectors for spread terminals, broken terminals, connectors/terminals that are not fully seated, or faulty terminal crimps. Closely inspect T3 Audio Amplifier X1 terminal 4 (B+ circuit 1140) and X1 terminal 8 (ground circuit 1450). Repair as needed. Refer to the appropriate Service Information for correct diagnostic test probe and connector repair information.

The radio can be reprogrammed using the Service System (SPS) and the latest calibrations in TIS2Web to reduce the volume of the chime. Thanks to Ryan Dorland 4 December 2015
