Description
If an error is detected in the system, the ABS warning lamp will turn on. In this case, perform self-diagnosis as follows
Operation Procedure
- Turn ignition switch OFF.
- Connect CONSULT-III and CONSULT-III CONVERTER to the data link connector. CAUTION: If CONSULT-III is used with no connection of CONSULT-III CONVERTER, malfunctions might be detected in self-diagnosis depending on control unit which carries out CAN communication.
- Turn ignition switch ON.
- Start engine and drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
- After stopping the vehicle, with the engine running, touch "START (NISSAN BASED VHCL)""ABS""SELF-DIAG RESULTS" in order on the CONSULT-III screen. CAUTION: If "START (NISSAN BASED VHCL)" is touched immediately after starting the engine or turning on the ignition switch"ABS" might not be displayed in the SELECT SYSTEM screen. In this case, repeat the operation from step 1 .
- The self-diagnostic results are displayed. (If necessary, the self-diagnostic results can be printed out by touching "PRINT"). When "NO DTC IS DETECTED" is displayed, check the ABS warning lamp.
- Conduct the appropriate inspection from the display item list, and repair or replace the malfunctioning component.
- Start engine and drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute. CAUTION: When a wheel sensor "short-circuit" is detected, if the vehicle is not driven at 30 km/h (19 MPH) for at least 1 minute, the ABS warning lamp will not turn off even if the malfunction is repaired.
- Turn ignition switch OFF to prepare for erasing the memory.
- Start the engine and touch "START (NISSAN BASED VHCL)""ABS""SELF-DIAG RESULTS""ERASE" in order on the CONSULT-III screen to erase the error memory. If "ABS" is not indicated, go to " «CONSULT-III DATA LINK CONNECTOR (DLC) CIRCUIT»(ref-337611-S08652965762009080600000) ". CAUTION: If the error memory is not erased, re-conduct the operation from step 5 .
- For the final inspection, drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute and confirm that the ABS warning lamp is off.
- After turning OFF the ignition switch, connect CONSULT-III and the CONSULT-III CONVERTER to the data link connector. CAUTION: If CONSULT-III is used with no connection of CONSULT-III CONVERTER, malfunctions might be detected in self-diagnosis depending on control unit which carries out CAN communication.
- Touch "START (NISSAN BASED VHCL)""ABS""DATA MONITOR" in order on the CONSULT-III screen. If "ABS" is not indicated, go to " «CONSULT-III DATA LINK CONNECTOR (DLC) CIRCUIT»(ref-337611-S08652965762009080600000) ". CAUTION: When "START (NISSAN BASED VHCL)" is touched immediately after starting the engine or turning on the ignition switch"ABS" might not be displayed in the SELECT SYSTEM screen. In this case, repeat the operation from step 2 .
- Return to the SELECT MONITOR ITEM screen, and touch "ECU INPUT SIGNALS""MAIN SIGNALS" or "SELECTION FROM MENU". Refer to the following information.
- When "START" is touched, the data monitor screen is displayed.
- Connect the CONSULT-III and CONSULT-III CONVERTER to the data link connector and start the engine. CAUTION: If CONSULT-III is used with no connection of CONSULT-III CONVERTER, malfunctions might be detected in self-diagnosis depending on control unit which carries out CAN communication.
- Touch "ABS". If "ABS" is not indicated, go to " «CONSULT-III DATA LINK CONNECTOR (DLC) CIRCUIT»(ref-337611-S08652965762009080600000) ".
- Touch "ACTIVE TEST".
- The SELECT TEST ITEM screen is displayed.
- Touch necessary test item.
- With the "MAIN SIGNALS" display selected, touch "START".
- The Active Test screen will be displayed, so conduct the following test.

SOLENOID VALVE OPERATION CHART
Note. If active test is performed with brake pedal depressed, pedal stroke may change. This is normal. "TEST IS STOPPED" is displayed approximately 10 seconds after operation starts. After "TEST IS STOPPED" is displayed, to perform test again, repeat Step 5 .
Pedal Vibration or ABS Operation Noise
Note. During ABS activation, pedal vibration may be felt and a noise may be heard. This is normal and does not indicate a malfunction.
- CHECK SYMPTOM Apply brake. Start engine. Does the symptom occur only when engine is started? YES >> Carry out self-diagnosis. Refer to " «SELF-DIAGNOSIS»(ref-337617-S13174347562009080600000) ". NO >> GO TO 2.
- RECHECK SYMPTOM Does the symptom occur only when electrical equipment switches (such as headlamps) are turned on? YES >> Check for radio, antenna or related wiring that is routed too close to the ABS actuator and electric unit (control unit) and reroute as necessary. NO >> Go to " «ABS WORKS FREQUENTLY»(ref-337617-S34822930652009080600000) ".
