• Models with VDC: 

BRC-207, "Wiring Diagram - Coupe"

 or 

BRC-215, "Wiring Diagram - Sedan"

Is the inspection result normal?

YES (Present error)>>Replace the ABS actuator and electric unit (control unit). Refer to the following.

• Models with ABS: 

BRC-66, "Exploded View"

• Models with TCS: 

BRC-137, "Exploded View"

• Models with VDC: 

BRC-239, "Exploded View"

YES (Past error)>>Error was detected in the ABS actuator and electric unit (control unit) branch line.

NO

>> Repair the power supply and the ground circuit.
