OPERATION PROCEDURE
1. Turn ignition switch OFF.
2. Perform “CONSULT-II Starting Procedure”. Refer to GI-38, "
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 “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-50, "
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-25, "
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 “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-39, "
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.

Basic InspectionNFS000QK
BASIC INSPECTION 1: BRAKE FLUID LEVEL, LEAK INSPECTION AND BRAKE PAD
1. Check fluid level in brake reservoir tank. If fluid level is low, refill brake fluid. Refer to BR-9, "CHECKING
BRAKE FLUID LEVEL" .
2. Check for leakage in brake tubes or hoses and around ABS actuator and electric unit (control unit). If
there is leaking or seeping fluid, check the following items.

If the brake tube connections at ABS actuator and electric unit (control unit) are loose, tighten flare nuts
to the specified torque. Then inspect again and confirm that there is no leakage.

If flare nuts or screws of ABS actuator and electric unit (control unit) are damaged and loose, replace
damaged parts. Then inspect again and confirm that there is no leakage.

If there is leakage at any location other than ABS actuator and electric unit (control unit) connections,
wipe away leakage with clean cloth. Then inspect again and confirm that there is no leakage.

If there is leakage from ABS actuator and electric unit (control unit), wipe away leakage with clean cloth.
Then inspect again. If there is still leakage, replace ABS actuator and electric unit (control unit).
CAUTION:
ABS actuator and electric unit (control unit) cannot be disassembled.
3. Check brake disc rotor and pads.

Front disc rotor: Refer to BR-27, "DISC ROTOR INSPECTION" .

Front brake pad: Refer to BR-22, "PAD WEAR INSPECTION" .

Rear disc rotor: Refer to BR-33, "DISC ROTOR INSPECTION" .

Rear brake pad: Refer to BR-28, "PAD WEAR INSPECTION" .
BASIC INSPECTION 2: LOOSENESS OF POWER SYSTEM TERMINALS AND BATTERY
Check battery for looseness on battery positive/negative terminals and ground connection. Also make sure
battery voltage does not drop and alternator is normal.
BASIC INSPECTION 3: ABS WARNING LAMP, BRAKE WARNING LAMP, VDC OFF INDICATOR
LAMP AND SLIP INDICATOR LAMP
ON and OFF Timing for Warning Lamp and Indicator Lamp
