CALIBRATION OF DECEL G SENSOR
CALIBRATION OF DECEL G SENSOR
DescriptionINFOID:0000000006222590
CAUTION:
Always perform the decel G sensor cal
ibration before driving when the following operation is per-
formed.
NOTE:
Yaw rate/side/decel G sensor calibration is performed when performing the decel G sensor calibration.
× : Required —: Not required
Work ProcedureINFOID:0000000006222591
Decel G sensor calibration
CAUTION:
Always use CONSULT-III for the d ecel 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.
