Diagnosis Procedure

INFOID:0000000006165890

Regarding Wiring Diagram information, refer to 

BRC-92, "Wiring Diagram"

.

1.

CONNECTOR INSPECTION

1. Turn ignition switch OFF.

2. Disconnect ABS actuator and electric unit (control unit) and steering angle sensor connectors.

3. Check terminals for deformation, disconnection, looseness, and so on. If any malfunction is found, repair

or replace terminals.
