Work Procedure

INFOID:0000000010428743

Decel G sensor calibration

CAUTION:

Always use CONSULT for the decel G sensor calibration. (It cannot be adjusted other than with CON-
SULT.) 
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

1.

Turn the ignition switch ON.

CAUTION:

Never start engine.

2.

Select “ABS”, “WORK SUPPORT”, “DECEL G SEN 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.

>> GO TO 3.

CONFIGURATION [ABS ACTUATOR AND ELECTRIC UNIT (CONTROL
UNIT)]

Work Procedure

INFOID:0000000010763725

CAUTION:

• Use “Manual Configuration” only when “TYPE ID” of ABS actuator and electric unit (control unit)

cannot be read.

• After configuration, turn the ignition switch from OFF to ON and check that the VDC warning lamp

turns OFF after staying illuminated for approximately two seconds.

• If an error occurs during configuration, start over from the beginning.

1.

CHECKING TYPE ID (1)

Use FAST (service parts catalogue) to search ABS actuator and electric unit (control unit) of the applicable
vehicle and find “Type ID”.

Is “Type ID” displayed?

YES

>> Print out “Type ID” and GO TO 2.

NO

>> “Configuration” is not required for ABS actuator and electric unit (control unit). Replace in the

usual manner. Refer to 

BRC-142, "Removal and Installation"

.

2.

CHECKING TYPE ID (2)

CONSULT Configuration

1.

Select “Before Replace ECU” of “Read/Write Configuration”.

2.

Check that “Type ID” is displayed on the CONSULT screen.

Is “Type ID” displayed?

YES

>> GO TO 3.

NO

>> GO TO 7.

3.

VERIFYING TYPE ID (1)

CONSULT Configuration

Compare a “Type ID” displayed on the CONSULT screen with the one searched by using FAST (service parts
catalogue) to check that these “Type ID” agree with each other.
NOTE:
For the “Type ID” searched by using FAST (service parts catalog), use the last five digits of the “Type ID”.

>> GO TO 4.

4.

SAVING TYPE ID

CONSULT Configuration

Save “Type ID” on CONSULT.

>> GO TO 5.

5.

REPLACING ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) (1)

Replace ABS actuator and electric unit (control unit). Refer to 

BRC-142, "Removal and Installation"

.

CAUTION:

Never perform the following work items:
• Air bleeding
• Adjustment of steering angle sensor neutral position
• Calibration of decel G sensor

>> GO TO 6.

6.

WRITING (AUTOMATIC WRITING)

CONSULT Configuration

1.
