SELF-DIAGNOSIS
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
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 carries out CAN communication.

3. Turn ignition switch ON.
4. Start engine and drive at approximately 30 km/h (19 MPH) or more 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.

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.

6. The self-diagnostic results are displayed. (If necessary, the self-diagnostic results can be printed out by touching PRINT.)

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 in order on the CONSULT-II screen to erase the error memory.
If ABS is not indicated, go to GI-40, "CONSULT-II Data Link Connector (DLC) Circuit". Testing and Inspection

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