CONSULT-II BASIC OPERATION PROCEDURE
1. Turn ignition switch OFF.





2. Connect CONSULT-II and CONSULT-II CONVERTER to the data link connector.

CAUTION: If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be detected in self-diagnosis depending on control unit which carry out CAN communication.

3. Turn ignition switch ON.





4. Touch "START (NISSAN BASED VHCL)".





5. Touch "ABS" in the "Diagnosis System Selection" screen. If "ABS" is not indicated, go to "CONSULT-II Data Link Connector (DLC) Circuit".

If an error is detected in the system, ABS warning lamp on the combination meter turn on. In this case, per form self-diagnosis as follows:

Operation Procedure
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to the data link connector.

CAUTION: If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be detected in self-diagnosis depending on control unit which carry out CAN communication.

3. Turn ignition switch ON.
4. Start engine and drive at approximately 30 km/h (19 MPH) for approximately 1 minute.
5. After stopping the vehicle, with the engine running, touch "START (NISSAN BASED VHCL)", "ABS", "SELF-DIAG RESULTS" in order on the CONSULT-II screen. If "ABS" is not indicated, go to "CONSULT-II Data Link Connector (DLC) Circuit".

6. The self-diagnostic results are displayed. (If necessary, the self-diagnostic results can be printed out by touching "PRINT".)
- When "NO FAILURE" is displayed, check the ABS warning lamp.

7. Conduct the appropriate inspection from the display item list, and repair or replace the malfunctioning component.
8. Start engine and drive at approximately 30 km/h (19 MPH) 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 everything is normal.

9. Turn ignition switch OFF to prepare for erasing the memory.
10. Start the engine and touch "START (NISSAN BASED VHCL)", "ABS", "SELF-DIAG RESULTS", "ERASE MEMORY" in order on the CONSULT-II screen to erase the error memory.

CAUTION: If the error memory is not erased, re-conduct the operation from step 5.

11. For the final inspection, drive at approximately 30 km/h (19 MPH) for approximately 1 minute and confirm that the ABS warning lamp is off.

Display Item List








Note 1: After completing repairs of the shorted sensor circuit, when ignition switch is turned ON, ABS warning lamp turns on. Check that ABS warning lamp turns off while driving the vehicle at approximately 30 km/h (19 MPH) for approximately 1 minute according to self-diagnosis procedure. In addition, if wheel sensor 2 is displayed for the wheels, check the wheel sensor circuit and also check the control unit power voltage.
Note 2: When errors are detected in several systems, including the CAN communication system [U1000], troubleshoot the CAN communication system.

DATA MONITOR
Operation Procedure
1. After turning OFF the ignition switch, connect CONSULT-II and the CONVERTER to the data link connector.

CAUTION: If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be detected in self-diagnosis depending on control unit which carry out CAN communication.

2. Touch "START (NISSAN BASED VHCL)", "ABS/TCS", "DATA MONITOR" in order on the CONSULT-II screen.
If "ABS" is not indicated, go to "CONSULT-II Data Link Connector (DLC) Circuit".

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 system selection screen. In this case, repeat the operation from step 2.
