Inspection Procedure

Check self-diagnosis results.

Is above displayed on the self-diagnosis display? 

YES: GO TO  2.

NO: INSPECTION END

1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector E30, check terminal for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or replace terminal.
2. Reconnect connector and perform self-diagnosis.

   OK or NG 

   OK: INSPECTION END

   NG: GO TO  3.

1. Check CAN communication system. Refer to CAN COMMUNICATION CIRCUIT .
2. Turn ignition switch OFF and disconnect steering angle sensor connector.
3. Check continuity between steering angle sensor harness connector M47 terminal 2 and ground.
