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.

For Fast and Accurate DiagnosisBFS000E6
PRECAUTIONS FOR DIAGNOSIS

Be sure to check the procedures of “How to Perform Trouble Diagnosis” in advance. Refer to GI-4, "Gen-
eral Precautions" .

Always adjust the neutral position of steering angle sensor before driving when removing and installing
ABS actuator and electric unit (control unit), steering angle sensor, suspension parts and adjusting align-
ment. Refer to BRC-40, "
Adjustment of Steering Angle Sensor Neutral Position" .

Always erase memory after completing trouble diagnosis. Refer to BRC-58, "ERASE MEMORY" .

When inspection of the continuity or voltage between modules or units is performed, check connector ter-
minals for disconnection, looseness, bend, or collapse. Repair or replace applicable part if any non-stan-
dard condition is detected.

Intermittent malfunctions may be caused by a poor connection in the harness, connectors, and terminals.
Move harnesses, harness connectors, and terminals by hand to make sure all connections are solid and
undamaged.

Do not to forcibly extend any connector terminal if a circuit tester is used for the check.

The symptom shown in the table may occur, but the system is operating normally.
Symptom Symptom description Result
Motor operation soundThis is the operation sound of the motor in the actuator and electric unit.Slight
sound may occur during VDC, TCS and ABS operation.
Normal
Just after the engine starts, the motor operating noise may be heard. This is a
normal status of the system operation check.
System operation check soundWhen engine starts, “click” sound may be heard from engine room. This is nor-
mal status of system operation check.Normal
VDC/TCS operation
(SLIP indicator lamp ON)TCS may activate momentarily if wheel speed changes when driving over
location where friction coefficient varies, when downshifting, or when fully
depressing accelerator pedal.
Normal
Cancel the VDC/
TCS function for
the inspection on
a chassis dyna-
mometer. Before the speed meter inspection, push VDC OFF switch to cancel the VDC/
TCS function.
When accelerator pedal is depressed on a chassis dynamometer (front wheel
fixing type), the vehicle speed will not increase. This is normal. It is result of
TCS being activated by stationary front wheels. The warning lamp may also
turn on to show “sensor system malfunction” in this case. This is also normal,
and is the result of the stationary front wheels being detected. Restart engine,
and drive the vehicle at 30 km/h (19 MPH) or more to make sure that the warn-
ing lamp no longer turns on.
ABS operation
(Longer stopping distance)When driving on roads with a low coefficient of friction, such as snowy roads or
gravel roads, the stopping distance is sometimes longer for vehicles equipped
with ABS. Therefore, when driving on such roads, drive at a sufficiently
reduced speed to be safe.Normal
Sluggish feelDepending on road conditions, the driver may have a sluggish feel. This is
because traction control, which controls engine and brakes to achieve optimal
traction, has the highest priority (for safety). As a result sometimes the driver
has a less slight sluggish feel in response than usual acceleration feel.Normal

TROUBLE DIAGNOSIS

Basic InspectionBFS000E7
BRAKE FLUID LEVEL, LEAKAGE AND BRAKE PAD
1. Check fluid level in the brake fluid reservoir tank. Refill the brake fluid if fluid level is low.
2. Check the area around the brake piping and actuator for leakage. If leakage or oozing is detected, check
as follows:

If ABS actuator and electric unit (control unit) connections are loose, tighten connections to the speci-
fied torque. Check again for leakage, and make sure that there is no fluid leakage.

If the flare nuts at the connections and the threads of the actuator are damaged, replace the damaged
parts. Then check again for leakage, and make sure that there is no fluid leak.

If leakage or oozing is detected on parts other than actuator connections, wipe with a clean cloth and
check again. If there is still leakage or oozing, replace the damaged part.

If leakage or oozing is detected on actuator body, wipe with a clean cloth and check again. If there is
still leakage or oozing, replace ABS actuator and electric unit (control unit).
CAUTION:
ABS actuator and electric unit (control unit) cannot be disassembled.
3. Check brake pad for wear. Refer to BR-26, "
PAD WEAR INSPECTION" , “FRONT DISC BRAKE”, BR-33,
"PAD WEAR INSPECTION" , “REAR DISC BRAKE”.
POWER SUPPLY CIRCUIT TERMINAL LOOSENESS AND BATTERY
Check battery for looseness on the battery positive/negative terminal and ground connection. Also make sure
that battery voltage does not drop.

AND SLIP INDICATOR LAMP
×: ON –: OFF
Note 1: Turns off after engine start
Note 2: The brake warning lamp turns on during parking brake operation (when switch is on) and brake fluid level sensor operation
(insufficient brake fluid).
1. Make sure that when the ignition switch is turned ON, the ABS warning lamp, VDC OFF indicator lamp
(when VDC OFF switch is off), and SLIP indicator lamp turn on for approximately 1 second, and that the
brake warning lamp turns on. If they do not turn on, perform CAN communication system diagnosis. Refer
to BRC-81, "
CAN Communication System" . Be sure to check VDC OFF switch before checking VDC OFF
indicator lamp. Refer to BRC-81, "
VDC OFF SWITCH" . Check combination meter if there is no malfunc-
tion in CAN communication system and VDC OFF switch. Refer to DI-4, "
COMBINATION METERS" .
2. Check if the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp turn off approximately
1 second after the ignition switch is turned ON, and if the brake warning lamp turns off after the engine is
started. If they do not turn off, perform self-diagnosis.
