< SERVICE INFORMATION >[VDC/TCS/ABS]
TROUBLE DIAGNOSIS FOR
SELF-DIAGNOSTIC ITEMS
1. Turn the ignition switch ON.
2. Check voltage between steering angle sensor connector M64
terminal 1 and ground.
3. Turn the ignition switch OFF.
4. Check resistance between steering angle sensor connector M64 terminal 3 and ground.
OK or NG
OK >> Check the CAN communication system. Refer to BRC-
79, "CAN Communication System Inspection". If the
CAN communication system is OK, replace steering angle sensor. Refer to BRC-91, "
Removal
and Installation".
NG >> Repair the circuit.
Yaw Rate/Side/Decel G Sensor System InspectionINFOID:0000000005612163
CAUTION:
Sudden turns (such as spin turns, acceleration turns), drifting, etc. When VDC function is OFF may
cause the yaw rate/side/decel G sensor system to indi cate a problem. However this is not a problem if
normal operation can be resumed after restarting the engine.
INSPECTION PROCEDURE
1.SELF-DIAGNOSIS RESULT CHECK
Check self-diagnosis results.
CAUTION:
When on a turntable, such as at a parking structure entrance, or when on a moving object with the
engine running, the VDC OFF indicator lamp migh t turn on and the self-diagnosis using the CONSULT-
III the yaw rate sensor system might be displayed, but in this case there is no problem with the yaw
rate sensor system. As soon as the vehicle leaves the turntable or moving object, restart the engine to
return the system to normal.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 2.
NO >> Inspection End.
2.CONNECTOR INSPECTION
Disconnect the ABS actuator and electric unit (contro l unit) and yaw rate/side/decel G sensor connectors.
Check the terminals for deformation, disconnection, looseness or damage.

Adjustment of Steering Angle Sensor Neutral PositionINFOID:0000000005612181
After removing/installing or replacing ABS actuator and electric unit (control unit), steering angle sensor, steer-
ing and suspension components which affect wheel alignment or after adjusting wheel alignment, be sure to
adjust neutral position of steering angle sensor before running vehicle.
NOTE:
Adjustment of steering angle sensor neutral position requires CONSULT-III.
1. Stop vehicle with front wheels in straight-ahead position.
2. Connect CONSULT-III to data link connector on vehicle, and turn ignition switch ON (do not start engine).
3. Touch “ABS”, “WORK SUPPORT” and “ST ANGLE SENSOR ADJUSTMENT” on CONSULT-III screen in
this order.
4. Touch “START”. CAUTION:
Do not touch steering wheel whil e adjusting steering angle sensor.
5. After approximately 10 seconds, touch “END”. (After approximately 60 seconds, it ends automatically.)
6. Turn ignition switch OFF, then turn it ON again.
7. Run vehicle with front wheels in straight-ahead position, then stop.
8. Select “DATA MONITOR”, “SELECTION FROM MENU”, and “STR ANGLE SIG” on CONSULT-III screen.
Then check that “STR ANGLE SIG” is within 0 ±2.5 deg. If value is more than specification, repeat steps 1
to 5.
9. Erase memory of ABS actuator and electric unit (control unit) and ECM.
10. Turn ignition switch to OFF.
