Work Procedure
INFOID:0000000006222591
Decel G sensor calibration
CAUTION:
Always use CONSULT-III for the decel G sensor calibration. (It cannot be adjusted other than with
CONSULT-III.)
NOTE:
Yaw rate/side/decel G sensor calibration is performed when performing the decel G sensor calibration.
1.
CHECK THE VEHICLE STATUS
1.
Steer the steering wheel to the straight-ahead position. Stop the vehicle on level surface.
2.
Stop the engine.
3.
Turn the ignition switch OFF.
Is the vehicle stopped in the straight-ahead position on level surface?
YES
>> GO TO 2.
NO
>> Steer the steering wheel to the straight-ahead position. Stop the vehicle on level surface.
2.
PERFORM DECEL G SENSOR CALIBRATION
CAUTION:
• Never allow passenger or load on the vehicle.
• Never apply vibration to the vehicle body when opening or closing door during calibration.
With CONSULT-III.
1.
Turn the ignition switch ON.
CAUTION:
Never start engine.
2.
Select “ABS”, “WORK SUPPORT”, “DECEL G-SENSOR CALIBRATION” in this order.
3.
Select “START”.
4.
After approx. 10 seconds, select “END”.
5.
Turn ignition switch OFF and then turn it ON again.
CAUTION:
Be sure to perform the operation above.

DTC CONFIRMATION PROCEDURE
1.
CHECK DTC DETECTION
With CONSULT-III.
1.
Turn the ignition switch OFF to ON.
2.
Perform self-diagnosis for “ABS”.
Is DTC “C1101”, “C1102”, “C1103” or “C1104” detected?
YES
>> Proceed to diagnosis procedure. Refer to
.
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000006222593
CAUTION:
Never check between wheel sensor harness connector terminals.
1.
CHECK WHEEL SENSOR HARNESS
1.
Turn the ignition switch OFF.
2.
Disconnect ABS actuator and electric unit (control unit) harness connector.
3.
Disconnect wheel sensor harness connector.
4.
Check continuity between ABS actuator and electric unit (control unit) harness connector and wheel sen-
sor harness connector. (Check continuity when steering wheel is steered to RH and LH, or center harness
in wheel housing is moved.)
