Nissan Maxima Service and Repair Manual: Symptom diagnosis
- VDC/TCS/ABS
- Excessive ABS function operation frequency
- Unexpected pedal reaction
- The braking distance is long
- ABS function does not operate
- Pedal vibration or abs operation sound occurs
- Vehicle jerks during VDC/TCS/ABS control
- Normal operating condition
Symptom Table If ABS warning lamp, SLIP indicator lamp turn ON, perform self-diagnosis. NOTE: 1: The ABS does not operate when the speed is 10 km/h (6 MPH) or less. 2: Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly depressed (just place a foot on it). However, this is normal. When shifting gears When driving on slippery road During cornering at high speed When passing over bumps or grooves [at approximately 50 mm (1.
Diagnosis Procedure 1.CHECK START Check front and rear brake force distribution using a brake tester. 2.CHECK FRONT AND REAR AXLE Make sure that there is no excessive play in the front and rear axles. 3.CHECK WHEEL SENSOR AND SENSOR ROTOR Check the following: Wheel sensor installation for damage. Sensor rotor installation for damage. Wheel sensor connector connection. Wheel sensor harness inspection. 4.CHECK ABS WARNING LAMP DISPLAY Make sure that the ABS warning lamp is turned off after the ignition switch is turned ON or when driving.
Diagnosis Procedure 1.CHECK BRAKE PEDAL STROKE Check brake pedal stroke. 2.CHECK FUNCTION Disconnect ABS actuator and electric unit (control unit) connector to deactivate ABS. Check if braking force is normal in this condition.Connect connector after inspection. 3.CHECK WHEEL SENSOR AND SENSOR ROTOR Check the following: Wheel sensor installation for damage. Sensor rotor installation for damage. Wheel sensor connector connection. Wheel sensor harness inspection. 4.CHECK ABS WARNING LAMP DISPLAY Make sure that the ABS warning lamp is turned off after the ignition switch is turned ON or when driving.
Diagnosis Procedure CAUTION: The stopping distance on slippery road surfaces might be longer with the ABS operating than when the ABS is not operating. 1.CHECK FUNCTION Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector to deactivate ABS. In this condition, check stopping distance. After inspection, connect connector. 2.CHECK WHEEL SENSOR AND SENSOR ROTOR Check the following: Wheel sensor installation for damage. Sensor rotor installation for damage. Wheel sensor connector connection. Wheel sensor harness inspection. 3.
Diagnosis Procedure CAUTION: ABS does not operate when speed is 10 km/h (6 MPH) or lower. 1.CHECK ABS WARNING LAMP DISPLAY Make sure that the ABS warning lamp turns OFF after ignition switch is turned on or when driving 2.CHECK WHEEL SENSOR AND SENSOR ROTOR Check the following: Wheel sensor installation for damage. Sensor rotor installation for damage. Wheel sensor connector connection. Wheel sensor harness inspection. 3.
Diagnosis Procedure CAUTION: Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly depressed (just place a foot on it).However, this is normal. When shifting gears When driving on slippery road During cornering at high speed When passing over bumps or grooves [at approximately 50 mm (1.97 in) or more] When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or higher] 1.SYMPTOM CHECK 1 Check if there is pedal vibration or operation sound when the engine is started. 2.SYMPTOM CHECK 2 Check symptoms when electrical component (headlamps, etc.) switches are operated. 3.
Diagnosis Procedure 1.SYMPTOM CHECK Check if the vehicle jerks during VDC/TCS/ABS control. 2.CHECK SELF-DIAGNOSIS RESULTS Perform self-diagnostic of ABS actuator and electric unit (control unit). 3.CHECK CONNECTOR Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector and check terminal for deformation, disconnection, looseness, etc. Securely connect connector and perform ABS actuator and electric unit (control unit) self-diagnosis. 4.CHECK ECM AND CVT SELF-DIAGNOSIS RESULTS Perform ECM and CVT self-diagnosis.
Description Symptom Result Slight vibrations are felt on the brake pedal and the operation noises occur, when VDC, TCS or ABS is activated. This is a normal condition due to the VDC, TCS or ABS activation. Stopping distance is longer than that of vehicles without ABS when the vehicle drives on rough, gravel, or snow-covered (fresh, deep snow) roads. 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. This is normal, and it is caused by the ABS operation check.
