TROUBLE DIAGNOSIS

Self-DiagnosisBFS000E3
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 and SLIP indicator lamp may be
turned on in a case of no malfunctioning.
OPERATION PROCEDURE
1. Turn ignition switch OFF.
2. Perform CONSULT-II Starting Procedure. Refer to GI-34, "
CONSULT-II Start Procedure" .
3. Turn ignition switch ON.
4. Start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
5. After stopping vehicle, with the engine running, touch “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. (Touch “PRINT” to print out self-diagnostic results, if necessary.)

Check ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp if “NO FAILURE” is dis-
played.
7. Perform the appropriate inspection from the display item list, and repair or replace the malfunctioning
component.
8. Start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
CAUTION:
When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning
lamp, VDC OFF indicator lamp and SLIP indicator lamp will not turn off even when the system is
normal unless the vehicle is driving at 30 km/h (19MPH) or more for approximately 1 minute.
ERASE MEMORY
1. Turn ignition switch OFF.
2. Start engine and touch “ABS”, “SELF-DIAG RESULTS”, “ERASE MEMORY” in order on the CONSULT-II
screen to erase the DTC memory.
CAUTION:
If the error memory is not erased, re-perform the operation from step 4.
3. Perform self-diagnosis again, and make sure that diagnostic memory is erased.
4. Drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute as the final inspection, and make
sure that the ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp turn off.
CAUTION:
VDC OFF switch should not stay in the “ON” position.
