SELF-DIAGNOSIS
Description

If an error is detected in the system, ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp
on the combination meter turn on. In this case, perform self-diagnosis as follows:

While CONSULT-II is used, ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp may be
turned on in a case of no malfunctioning.
Operation Procedure
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to 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) or more for approximately 1 minute.
5. After stopping 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 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 1. If it cannot be shown after several attempts, ABS actuator and electric
unit (control unit) may have malfunctioned.
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 ABS warning lamp, VDC OFF indicator lamp and SLIP indica-
tor lamp.
7. Perform the appropriate inspection from the display item list, and repair or replace the malfunctioning
component.
8. Drive the vehicle at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
CAUTION:

In a case that a wheel sensor is malfunctioning, ABS warning lamp, VDC OFF indicator lamp,
SLIP indicator lamp will turn on. If vehicle is not driven at approximately 30 km/h (19 MPH) or
more for at least approximately 1 minute after repair of the wheel sensor system, ABS warning
lamp, VDC OFF indicator lamp and SLIP indicator lamp may not turn off even if everything is
normal. Check again to make sure that there is no malfunction on other parts.
9. Turn ignition switch OFF to prepare for erasing the memory.
10. Start 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.
If “ABS” is not indicated, go to GI-40, "
CONSULT-II Data Link Connector (DLC) Circuit" .
CAUTION:
If the error memory is not erased, re-perform the operation from step 5.
11. For the final inspection, drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute and
confirm that ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp are OFF.
