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.

UNIT)]
Work Procedure
INFOID:0000000010723660
CAUTION:
• Use “Instruction 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.
• LHD models: Refer to
BRC-217, "LHD : Removal and Installation"
• RHD models: Refer to
BRC-220, "RHD : 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 the ABS actuator and electric unit (control unit).
• LHD models: Refer to
BRC-217, "LHD : Removal and Installation"
• RHD models: Refer to
BRC-220, "RHD : 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.
