3 PRECAUTIONS PRECAUTIONS PFP:00001 Precautions for Supplemental Restraint System (SRS) AIR BAG and SEAT BELT PRE-TENSIONER EFS000NX The Supplemental Restraint System such as AIR BAG and SEAT BELT PRE-TENSIONER, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. Information necessary to service the system safely is included in the SRS and SB section of this Service Manual. WARNING: To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS section. Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. Precautions for Brake System Use brake fluid DOT 3. Never reuse drained brake fluid. Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is splashed on painted areas, wash it away with water immediately. Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of hydraulic system. Use flare nut wrench when removing and installing brake tubes. Always torque brake lines when installing. Before working, turn the ignition switch OFF and disconnect the connectors for the ABS actuator and control module or the battery terminals. Burnish the brake contact surfaces after refinishing or replacing drums or rotors, after replacing pads or linings, or if a soft pedal occurs at very low mileage. Refer to BR-25, "Brake Burnishing Procedure". WARNING: SBR686C Clean brakes with a vacuum dust collector to minimize risk of health hazard from powder caused by friction. Precautions for Brake Control EFS000GV EFS000GW During ABS operation, the brake pedal vibrates lightly and its mechanical noise may be heard. This is a normal condition. Just after starting the vehicle after ignition switch ON, the brake pedal may vibrate or the motor operating noise may be heard from the engine compartment. This is a normal status of the operation check. The stopping distance may be longer than that of vehicles without ABS when the vehicle drives on rough, gravel, or snowy (fresh deep snow) road. If a malfunction is indicated by the ABS warning lamp, or other warning lamps, collect the necessary information from the customer (what symptoms are present under what conditions) and find out the possible causes before starting the service. Besides the electrical system inspection, check the booster operation, brake fluid level, and oil leaks. If the tire size and type are used in a improper combination, or the brake pads are not NISSAN genuine parts, the stopping distance or steering stability may deteriorate. If there is a radio, antenna, or antenna lead-in wire (including wiring) near the control unit, the ABS function may have a malfunction or error. If aftermarket parts (e.g. Car stereo equipment, CD player) have been installed, check the electrical harnesses for pinches, open, and improper wiring. A B C D E BRC G H I J K L M BRC-3

4 PRECAUTIONS Precautions for Trouble Diagnosis CAN SYSTEM Do not apply voltage of 7.0V or higher to the measurement terminals. Use the tester with its open terminal voltage being 7.0V or less. Precautions for Harness Repair CAN SYSTEM Solder the repaired parts, and wrap with tape. [Frays of twisted line must be within 110 mm (4.33 in)] EFS001OW EFS001OX PKIA0306E Do not perform bypass wire connections for the repair parts. (The spliced wire will become separated and the characteristics of twisted line will be lost.) PKIA0307E BRC-4

5 ON-VEHICLE SERVICE ON-VEHICLE SERVICE Adjustment of Neutral Position of Steering Angle Sensor PFP:00000 After removing/installing or replacing the VDC/TCS/ABS control unit, steering angle sensor, steering components, suspension components, and tires, or after adjusting the wheel alignment, make sure to adjust the neutral position of the steering angle sensor before running the vehicle. CAUTION: To adjust the neutral position of the steering angle sensor, make sure to use CONSULT-II. (Adjustment cannot be done other than CONSULT-II.) 1. Stop the vehicle with the front wheels in the straight-ahead position. 2. Connect CONSULT-II to data link connector on the vehicle, and turn the ignition switch to ON position (engine not running). 3. Touch VDC, WORK SUPPORT and ANGLE SENSOR ADJUSTMNET on the CONSULT-II screen in this order. EFS000GY A B C D E BRC PBIB0196E 4. Touch START. CAUTION: Do not touch the steering wheel while adjusting the steering angle sensor. 5. After approximately 10 seconds, touch END. (After approximately 60 seconds, it ends automatically.) 6. Turn the ignition switch OFF, then turn it ON again. CAUTION: Make sure to carry out the above operation. 7. Run the vehicle with the front wheels in the straight-ahead position, then stop. SFIA0168E 8. Select DATA MONITOR, CONTROL MODULE INPUT ITEM, and STEERING ANGLE SIGNAL on the CONSULT-II screen. Then check that the STEERING ANGLE SIGNAL is within 0±2.5deg. If the value is more than the specification, repeat steps 1 to Erase the memory of VDC/TCS/ABS control module and ECM. 10. Turn the ignition switch OFF. G H I J K L M BRC-5

6 GENERAL INFORMATION Fail-Safe GENERAL INFORMATION PFP:00000 ABS SYSTEM If a malfunction occurs in the electrical system, the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp in the meter will turn ON. In this condition, the VDC/TCS/ABS and EBD become one of the following conditions by the fail-safe function. 1. Only EBD operates. The same condition as that of models without VDC/TCS/ABS 2. VDC/TCS/ABS and EBD do not operate. Only normal brake operates on 4 wheels. NOTE: In the step 1 shown above, the self-diagnosis is carried out at the ignition switch is turned ON and when the vehicle initial starts. ABS self-diagnosis noise may be heard as usual. VDC/TCS SYSTEM If a malfunction occurs in the electrical system, the VDC OFF indicator lamp and SLIP indicator lamp in the meter turn on. In this condition, VDC/TCS will be deactivated and it becomes equal to that of models without VDC/TCS. However, ABS is controlled normally. If a malfunction occurs in the throttle control system, VDC/TCS control does not operate. Only ABS control operates normally. CAUTION: If the fail-safe function operates, carry out the self-diagnosis for VDC/TCS/ABS control system. Hydraulic Circuit EFS000GZ EFS000H0 CAUTION: When installing, check for twist and fracture. Make sure that there is no interference with other parts when turning the steering clockwise or counter clockwise. The brake piping is an important safety part. If a brake fluid leak is detected, always disassemble and replace with a new one, if necessary. ABS Functions SFIA0169E 1. During ABS operation, the brake pedal lightly vibrates and its mechanical noise may be heard. This is a normal condition. 2. When starting the engine, or just after starting the vehicle, the brake pedal may vibrate or the motor operating noise may be heard from the engine compartment. This is a normal status of the operation check. 3. The stopping distance may be longer than that of vehicles without ABS when the vehicle drives on rough, gravel, or snowy (fresh deep snow) road. 4. EBD is integrated in VDC/TCS/ABS system. EFS000H1 BRC-6

7 GENERAL INFORMATION TCS Functions 1. With the wheel speed sensor signal from 4 wheels, the VDC/TCS/ABS control module detects a wheel spin on the drive wheels. If a wheel spins, the control module controls brake fluid pressure on rear LH and RH, and cuts the fuel to the engine. It also closes the throttle valve to reduce the engine torque. Furthermore, throttle position is controlled to the appropriate engine torque. 2. Depending on road circumstances, the driver may have a sluggish feel. This is not abnormal, because the optimum traction has the highest priority by TCS operation. 3. When the vehicle is passing through a road where the surface friction coefficient varies, downshifting or depressing the accelerator pedal fully may activate TCS temporarily. 4. During TCS operation, it informs a driver of system operation by flashing SLIP indicator lamp. VDC Functions 1. In addition to the ABS/TCS function, VDC detects the driver's steering operation amount and brake operation amount from the steering angle sensor and pressure sensor. Using the information from the yaw rate/transverse G-sensor and wheel speed sensor, VDC judges the driving condition (conditions of under steer and over steer) to improve the stability by controlling the brake on 4 wheels and engine output. 2. During VDC operation, the SLIP indicator lamp flashes to inform the driver of the operation. 3. During VDC operation, the body and the brake pedal lightly vibrate and their mechanical noise may be heard. This is a normal condition. 4. If the vehicle is rotated on a turn table, or rolled and rocked on a ship, the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp may turn ON. In this case, start the engine on a normal road again. If the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp turn OFF after the restart, it is normal. 5. When driving in a steep slope such as a bank, the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp may turn ON. In this case, start the engine on a normal road again. If the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp turn off after the restart, it is normal.

8 CAN Communication GENERAL INFORMATION SYSTEM DESCRIPTION CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.

11 How to Perform Trouble Diagnoses for Quick and Accurate Repair INTRODUCTION PFP:00004 The most important point to perform the trouble diagnosis is to understand the systems (control and mechanism) in the vehicle thoroughly. It is also important to clarify the customer complaints before inspection. First of all, reproduce the symptom, and understand it fully. Ask the customer about his/her complaints carefully. In some cases, it will be necessary to check the symptoms by driving the vehicle with the customer. CAUTION: Customers are not professional. It is dangerous to make an easy guess like maybe the customer means that..., or maybe the customer mentions this symptom. It is essential to check symptoms right from the beginning in order to repair a malfunction completely. For an intermittent malfunction, it is important to reproduce the symptom based on an interview with the customer and past examples. Do not perform an inspection on an ad hoc basis. Most intermittent malfunctions are caused by poor contacts. In this case, it will be effective to shake the suspected harness or connector by hand. When repairs are performed without any trouble diagnosis. Repair work is not confirmed if it's done correctly. After the diagnosis, make sure to carry out erase memory. Refer to BRC-33, "SELF-DIAGNOSIS". For an intermittent malfunction, move the harness or harness connector by hand to check the poor contact or false open circuit. Always read the GI Section, General Information to check the general guidelines and to confirm the general precautions. EFS000H5 SEF234G SEF233G A B C D E BRC G H I J K L M BRC-11

13 ASKING COMPLAINTS Complaints against a malfunction vary depending on each person. It is important to clarify the customer complaints. Ask the customer about what symptoms are present under what conditions. Use the information to reproduce the symptom while driving. It is also important to use the diagnosis sheet to understand what type of trouble the customer having. A B C EXAMPLE OF DIAGNOSIS SHEET SBR339B D E BRC G H I J K L M SFIA0791E BRC-13

SELF-DIAGNOSIS Description If a malfunction is detected in the system, the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp on the meter turn on. In this case, perform the self-diagnosis as follows: Procedure 1. Perform a BRC-40, "Basic Inspection" using information from the customer. 2. After the ignition switch is turned OFF, connect the CONSULT-II connector to the vehicle-side data link connector. The data link connector is on the lower instrument cover). 3. Start the engine and drive at approx. 30 km/h (19 MPH) for approx. 1 minute. 4. After stopping the vehicle, with the engine still idling, touch START (NISSAN BASED VHCL), VDC, SELF-DIAG RESULTS on the CONSULT-II screen in this order. CAUTION: Just after starting the engine, or turning the ignition switch PBIB0196E ON, VDC may not be displayed on the system selection screen even if START (NISSAN BASED VHCL) is touched. In this case, start the self-diagnosis again from step 2. If it cannot be shown after several attempts, the VDC/TCS/ABS control unit may malfunction. Repair or replace the control unit. 5. The self-diagnosis result is displayed. (If necessary, touch PRINT to print the self-diagnosis result.) When NO FAILURE is shown, check the ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp. BRC-39, "Refer to For Correct and Quick Diagnosis.". CONSULT-II self-diagnosis results are displayed without regard to occurrence timing. In some case, the later ones (timing value is small) appear on the next screen. 6. Go to appropriate Inspection chart according to Indication item list and repair or replace as necessary. 7. Start the engine and drive at approx. 30 km/h (19 MPH) for approx. 1 minute. CAUTION: Check again to make sure that there is NO MALFUNCTION on other parts. 8. Turn the ignition switch OFF to prepare for erasing the memory. 9. Start the engine and touch START (NISSAN BASED VHCL), VDC, SELF-DIAGNOSIS RESULTS and ERASE MEMORY on CONSULT-II screen in this order to ease the memory. CAUTION: If the memory cannot be erased, go to step Drive the vehicle at approx. 30 km/h (19 MPH) and check that the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp stay off.
