Diagnostic test mode Work support Function This mode enables a technician to adjust some devices faster and more accurately by following the indications on CONSULT-III. Self diagnostic result Self-diagnostic results can be read and erased quickly. Data monitor Input/Output data in the ABS actuator and electric unit (control unit) can be read. Active test CONSULT-III drives some actuators apart from the ABS actuator and electric unit (control unit) and also shifts some parameters in a specified range. ECU identification ABS actuator and electric unit (control unit) part number can be read. WORK SUPPORT Item Description ST ANGLE SENSOR ADJUSTMENT Adjusts the neutral position of the steering angle sensor. DECEL G SEN CALIBRATION Calibrates decel G sensor. SELF DIAGNOSTIC RESULT Operation Procedure Before performing the self-diagnosis for “ABS” with CONSULT-III, start the engine and drive the vehicle at 30 km/h (19 MPH) or more for approximately 1 minute. Display Item List Refer to BRC-96, "DTC No. Index". How to Erase Self-diagnosis Results After erasing DTC memory for “ABS” with CONSULT-III, start the engine and drive the vehicle at 30 km/h (19 MPH) or more for approximately 1 minute as the final inspection, and make sure that the ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp turn OFF. CAUTION: If memory cannot be erased, perform applicable diagnosis. NOTE: • When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp will not turn OFF even when the system is normal unless the vehicle is driving at approximately 30 km/h (19 MPH) or more for approximately 1 minute. • Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake fluid level switch operation (when brake fluid is insufficient). • VDC OFF switch should not stay “ON” position.

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.

G H I J K L M N O P Revision: 2009 September BRC-103 2010 Murano NORMAL OPERATING CONDITION [VDC/TCS/ABS] < SYMPTOM DIAGNOSIS > NORMAL OPERATING CONDITION Description INFOID:0000000005517407 Symptom Result Slight vibrations are felt on the brake pedal and the operation noises occur, when VDC, TCS or ABS is activated. Stopping distance is longer than that of vehicles without ABS when the vehicle drives on rough, gravel, or snow-covered (fresh, deep snow) roads. This is a normal condition due to the VDC, TCS or ABS activation. The brake pedal moves and generates noises, when TCS or VDC is activated due to rapid acceleration or sharp turn. The brake pedal vibrates and motor operation noises occur from the engine room, after the engine starts and just after the vehicle starts. Depending on the road conditions, the driver may experience a sluggish feel. TCS may activate momentarily if wheel speed changes when driving over location where friction coefficient varies, when downshifting, or when fully depressing accelerator pedal. The ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp may turn ON when the vehicle is subject to strong shaking or large vibration, such as when the vehicle is rotating on a turntable or located on a ship while the engine is running. VDC may not operate normally or the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp may illuminate, when running on a special road that is extremely slanted (e.g. bank in a circuit course). A malfunction may occur in the yaw rate/side G sensor system, when the vehicle turns sharply, such as during a spin turn, axle turn, or drift driving, while the VDC function is off (VDC OFF indicator lamp illuminated). The vehicle speed will not increase even though the accelerator pedal is depressed, when inspecting the speedometer on a 2-wheel chassis dynamometer. Revision: 2009 September BRC-104 This is a normal, and it is caused by the ABS operation check. This is normal, because TCS places the highest priority on the optimum traction (stability). In this case, restart the engine on a normal road. If the normal condition is restored, there is no malfunction. At that time, erase the selfdiagnosis memory. Normal (Deactivate the VDC/TCS function before performing an inspection on a chassis dynamometer.) 2010 Murano PRECAUTIONS [VDC/TCS/ABS] < PRECAUTION > PRECAUTION A PRECAUTIONS FOR USA AND CANADA B FOR USA AND CANADA : Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000005688780 C 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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS D system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this E 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 BRC 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 G Module, see the “SRS AIR BAG”. • Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual.
