TROUBLE DIAGNOSIS

Revision: 2005 August

2005 Murano

SELF-DIAGNOSIS
Description

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

Operation Procedure

Turn ignition switch OFF.

Connect CONSULT-II and CONSULT-II CONVERTER to the 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.

Turn ignition switch ON.

Start engine and drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute.

After stopping the vehicle, with engine running at idle speed, touch “START (NISSAN BASED VHCL)”,
“ABS”, “SELF-DIAG RESULTS” in order on the CONSULT-II screen.
If “ABS” is not indicated, go to

GI-39, "CONSULT-II Data Link Connector (DLC) Circuit"

CAUTION:

●

If there is no error during CONSULT-II use, ABS warning lamp, VDC OFF indicator lamp, SLIP
indicator lamp may be turned ON/OFF.

●

If “START (NISSAN BASED VHCL)” is touched immediately after starting engine or turning on
ignition switch, “ABS” might not be displayed in the System Selection screen. In this case,
repeat the operation from step 1. If it connect be shown after several attempts, ABS actuator
and electric unit (control unit) may have malfunction. Repair or replace control unit.

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 indi-
cator lamp.

Conduct the appropriate inspection from the display item list, and repair or replace the malfunctioning
component.

Start engine and drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute.

CAUTION:

●

When a wheel sensor “short-circuit” is detected, if the vehicle is not driven at 30 km/h (19 MPH)
for at least 1 minute, ABS warning lamp will not turn off even if everything is normal.

●

Check again to make sure that there is no malfunction on other parts.

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.

CAUTION:

If the error memory is not erased, re-conduct the operation from step 5.

11. For 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.

CAUTION:

VDC “OFF” switch should not stay in the “ON” position.

PRECAUTIONS FOR DIAGNOSIS

●

Before performing diagnosis, always read precautions. Refer to

GI-4, "General Precautions"

●

If ABS actuator and electric unit (control unit), steering angle sensor, steering system parts, suspension
system parts, or tires have been replaced, or if alignment has been adjusted, be sure to adjust neutral
position of steering angle sensor before driving. Refer to

BRC-49, "Adjustment of Steering Angle Sensor

Neutral Position"

●

After diagnosis is finished, be sure to erase memory. Refer to

BRC-72, "Operation Procedure"

●

When checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse of connector terminals. If any malfunction is found, repair or replace connector termi-
nals.

●

For intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals.
Move harness, harness connector, and terminals to check for poor connections.

●

If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.

●

To use CONSULT-II to perform self-diagnosis of ABS actuator and electric unit (control unit), active tests,
or work support, first stop work, then connect CONSULT-II and select “ABS”.

●

While self-diagnosis results of CONSULT-II shows malfunction, if CONSULT-II active test is performed, an
engine system error may be indicated. In this case, start engine to resume the normal screen.

●

VDC/TCS/ABS system electronically controls brake operation and engine output. The following symptoms
may be caused by normal operations:

●

When CONSULT-II is used, ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp may be
ON/OFF.

Symptom

Symptom description

Result

Motor operation noise

This is noise of motor inside ABS actuator and electric unit (control unit).
Slight noise may occur during VDC, TCS, and ABS operation.

Normal

When the vehicle speed goes over 20 km/h (12.5MPH), the motor and
valves operating noise may be heard. It happens only once after IGN
(ignition) is ON. This is a normal status of the system operation check.

System operation check
noise

When engine starts, slight “click” noise may be heard from engine com-
partment. This is normal and is part of system operation check.

Normal

VDC/TCS operation
(SLIP lamp Blinking)

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 chas-
sis dynamometer.

For inspection of speedometer or other instruments, press
VDC OFF SW to turn VDC/TCS function off.

When accelerator pedal is depressed on a chassis dynamometer (fixed
front-wheel type), vehicle speed will not increase. This is not normal. It is
result of TCS being activated by stationary front wheels. Warning lamp
may also illuminate to indicate “sensor system error”. This is also nor-
mal, and is the result of the stationary front wheels being detected. To be
certain, restart engine, and drive vehicle at 30 km/h (19 MPH) or above.
Make sure that warning lamp does not illuminate.

ABS operation (Longer stop-
ping distance)

On roads with low friction coefficients, such as snowy roads or gravel
roads, vehicles with ABS may require a longer stopping distance. There-
fore, when driving on such roads, avoid overconfidence and keep speed
sufficiently low.

Normal

Insufficient feeling of accel-
eration

Depending on road conditions, driver may feel that feeling of accelera-
tion is insufficient. This is because traction control, which controls
engine and brakes to achieve optimal traction, has the highest priority
(for safety). As a result, there may be times when acceleration is slightly
less than usual for the same accelerator pedal operation.

–: OFF

NOTE:
1.

Brake warning lamp will turn on in case of operating parking brake (switch turned on) or of actuating brake
fluid level switch (brake fluid is insufficient).

After starting engine, turn OFF.

Basic Inspection

AFS00203

BASIC INSPECTION 1 BRAKE FLUID LEVEL, LEAKS, AND BRAKE PADS

Check fluid level in the brake reservoir tank. If fluid level is low, refill the brake fluid.

Check the brake piping and around the ABS actuator and electric unit (control unit) for leaks. If leakage or
seepage is found, check the following items.

●

If ABS actuator and electric unit (control unit) connection is loose, tighten the piping to the specified
torque and make sure there are no leaks.

●

If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) screw,
replace the damaged part and re-conduct the leak inspection to make sure there are no leaks.

●

If there is leakage or seepage at any location other than ABS actuator and electric unit (control unit)
connection, wipe away leakage or seepage with clean cloth. Then inspect again and confirm the there
is on leakage.

●

If there is leakage from ABS actuator and electric unit (control unit), wipe away leakage or seepage with
clean cloth. Then inspect again. If there is leakage or seepage, replace ABS actuator and electric unit
(control unit).

CAUTION:

ABS actuator body can not be disassembled.

Check brake disc and pads. Refer to

BR-28, "Removal and Installation of Brake Pad"

in “Front Disc

Brake” and

BR-34, "Removal and Installation of Brake Pad"

in “Rear Disc Brake”.

BASIC INSPECTION 2 POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION

Make sure the battery positive cable, negative cable and ground connection are not loose. If looseness is
detected, tighten the piping to the specified torquer. In addition, check the battery voltage to make sure it has
not dropped and the altimeter is normal.

BASIC INSPECTION 3 ABS WARNING LAMP, VDC OFF INDICATOR LAMP, SLIP INDICATOR
LAMP INSPECTION

Make sure that ABS warning lamp, VDC OFF indicator lamp (when VDC OFF switch is OFF), and SLIP
indicator lamp turn ON when ignition switch is turned ON. If they do not, check the VDC OFF indicator
lamp and then VDC OFF switch. Refer to

BRC-100, "VDC OFF SWITCH"

. Check CAN communications.

Refer to
