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 performs CAN communication.
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 “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 “SELECT SYSTEM” screen. In this case,
repeat the operation from step 1.
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. Refer to BRC-53, "
Inspection 19: Warning Lamp and Indicator Lamp Circuit" .
7. Perform the appropriate inspection from display item list, and repair or replace the malfunctioning compo-
nent.Refer to BRC-24, "
DISPLAY ITEM LIST" .
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, SLIP indicator lamp and brake warning lamp will not turn off even
when the system is normal unless the vehicle is driving at approximately 30 km/h (19 MPH) or
more for approximately 1 minute.
ERASE MEMORY
1. Turn ignition switch OFF.
2. Start engine and touch “START (NISSAN BASED VHCL)”, “ABS”, “SELF-DIAG RESULTS”, “ERASE
MEMORY” in order on the CONSULT-II screen to erase the diagnostic memory.
If “ABS” is not indicated, go to GI-40, "
CONSULT-II Data Link Connector (DLC) Circuit" .
CAUTION:
If the diagnostic 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, SLIP indicator lamp and brake warning lamp
turn off.
NOTE:
Brake warning lamp will turn on in case of parking brake operation (when switch is ON) or of brake fluid
level switch operation (when brake fluid is insufficient).
VDC OFF switch should not stay "ON" position.
