TROUBLE DIAGNOSIS
Revision: 2006 January2006 M35/M45
For Fast and Accurate DiagnosisNFS000QJ
PRECAUTIONS FOR DIAGNOSIS
Before performing diagnosis, always read General Information (GI) to confirm general precautions. Refer
to GI-4, "
General Precautions" .
If steering angle sensor, steering system parts, suspension system parts, ABS actuator and electric unit
(control unit) or tires have been replaced, or if wheel alignment has been adjusted, be sure to adjust neu-
tral position of steering angle sensor before driving. Refer to BRC-6, "
Adjustment of Steering Angle Sen-
sor Neutral Position" .
After diagnosis is finished, be sure to erase memory. Refer to BRC-23, "ERASE MEMORY" .
When checking continuity and voltage between unit, be sure to check for disconnection, looseness, bend,
or collapse of connector terminals. If any malfunction is found, repair or replace connector terminals.
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.
The following symptoms may be caused by normal operations.
Symptom Symptom description Result
Motor operation soundThis is sound of motor inside VDC actuator. Slight sound may occur
during VDC, TCS, and ABS operation.
Normal
Just after engine starts, the motor operating sound may be heard. This
is a normal condition of the system operation check.
System operation check
soundWhen engine starts, slight “click” sound may be heard from engine
room. This is normal and is part 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 varies, when downshifting, or when fully
depressing accelerator pedal.Normal
Cancel the VDC/TCS
function for the
inspection on a chas-
sis dynamometer. When checking speed meter etc. with a 2-wheel-drive chassis dyna-
mometer, vehicle speed is not increased by pressing down on the accel-
erator.
ABS operation (Longer stop-
ping distance)On roads with low friction, such as snowy roads or gravel roads, vehi-
cles with ABS may require a longer stopping distance. Therefore, when
driving on such roads, avoid overconfidence and keep speed sufficiently
low.Normal
Insufficient feeling of accel-
erationDepending 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.Normal

3. CHECK STOP LAMP SWITCH CIRCUIT
1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector E30.
2. Check voltage between ABS actuator and electric unit (control
unit) harness connector E30 terminal 30 and ground.
OK or NG
OK >> Perform self-diagnosis.
NG >>
Repair or replace stop lamp switch circuit.
Perform the self-diagnosis, and make sure that the result shows NO DTC IS DETECTED.
Inspection 11: Yaw Rate/Side G Sensor CircuitNFS000QV
CAUTION:
Sudden turns (such as spin turns, acceleration turns), drifting, etc., when VDC function is off (VDC
OFF switch "ON") may cause yaw rate/side G sensor system to indicate a malfunction. However,
this is not a malfunction, if normal operation can be resumed after restarting engine. Then erase
memory of self-diagnosis.
If vehicle is on turn-table at entrance to parking garage, or on other moving surface, VDC OFF
indicator lamp may illuminate and CONSULT-II self-diagnosis may indicate yaw rate sensor sys-
tem malfunction. However, in this case there is no malfunction in yaw rate sensor system. Take
vehicle off of turn-table or other moving surface, and start engine. Results will return to normal.
And after doing spin turns or acceleration turns with VDC function is being off (VDC OFF switch
“ON”), too, the results will return to a normal condition by re-starting vehicle.
INSPECTION PROCEDURE
