10.Turn the wheel by hand and check the change in 

braking force when the brake pedal is depressed. 
When using the braking force tester, depress the 
brake pedal until the braking force is at the 
following values, and check that the braking force 
changes to the brake drag force reading taken in 
step 2 when the actuator is force-driven. The 
result should be as shown in the diagram above.

11.If the result of inspection is abnormal, repair 

according to the Diagnosis Table below.

12.After inspection, disconnect MUT-III immediately 

after turning the ignition switch to the "LOCK" 
(OFF) position.

IN THE EVENT OF A DISCHARGED 
BATTERY

M1355006200027

WARNING

If the ABS is not operating, the vehicle will be 
unstable during braking, Do not drive the 
vehicle with the TCL/ASC-ECU connector 
disconnected or with the TCL/ASC not 
operating for any other reason.

If the engine is started using a booster cable when 
the battery is completely flat, and the vehicle is then 
driven without waiting for the battery to be recharged, 
the engine may misfire and it may not be possible to 
drive the vehicle. This is because the ABS consumes 
a large amount of current when carrying out its initial 
checks. If this happens, recharge the battery fully.

G AND YAW LATE SENSOR 
CALIBRATION

M1355009300023

CAUTION

If the work below is done, finally calibrate the G 
and yaw late sensor. This is necessary because 
the TCL/ASC-ECU should update the G and yaw 
late sensor neutral point.

• G and yaw late sensor replacement
• TCL/ASC-ECU replacement

1. Park the vehicle on a level surface.

CAUTION

2.

Before connecting or disconnecting the MUT-III, 
turn the ignition switch to the "LOCK" (OFF) 
position.
Connect MUT-III to the 16-pin diagnosis connector.

3. Turn the ignition switch to the "ON" position.
4. Select "Interactive Diagnosis".
5. Select "Special function".
6. Select "G and yaw rate sensor".
7. Select "Calibration".
8. Turn the ignition switch to the "LOCK" (OFF) 

position.

9. Disconnect MUT-III.

STEERING WHEEL SENSOR 
CALIBRATION

M1355009200026

CAUTION

If the work below is done, finally calibrate the 
steering wheel sensor. This is necessary 
because the TCL/ASC-ECU should update the 
steering wheel sensor neutral point.

• Front alignment adjustment
• Steering wheel sensor removal and 

installation

• TCL/ASC-ECU replacement

1. Park the vehicle on a level surface.
