Self-diagnostic results

ST ANG SEN CIRCUIT

Is the above displayed in the self-diagnosis item? 

1. YES: GO TO 2.
2. NO: INSPECTION END

1. Disconnect steering angle sensor connector and ABS actuator and electric unit (control unit) connector and check terminals for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or replace terminal.
2. Reconnect connectors and perform an ABS actuator and electric unit (control unit) self-diagnosis again.

OK or NG 

1. OK: Connector terminal contact is loose, damaged, open or shorted.
2. NG: GO TO 3.

1. Check CAN communication circuit. Refer to "INSPECTION 14: CAN COMMUNICATION CIRCUIT ".
2. Turn ignition switch OFF and disconnect steering angle sensor connector.
3. Check continuity between steering angle sensor harness connector M14 and ground.

   3 (G/R)	-	12V

OK or NG 

1. OK: GO TO 4.
2. NG: If the open or short in harness, repair or replace harness.

Check steering wheel play. Refer to "CHECKING STEERING WHEEL PLAY ".

OK or NG 

1. OK: GO TO 5
2. NG: Adjust steering wheel play.

1. Connect steering angle sensor and ABS actuator and electric unit (control unit) connectors.
2. Perform "DATA MONITOR " of the "STEERING ANGLE SIGNAL" to check if the status is normal.
   STEERING CONDITION - DATA MONITOR
   
   

   Steering condition	Data monitor
   Straight-ahead	-3.5 deg - +3.5 deg
   Turn wheel to the right by 90°.	Approx. -90 deg
   Turn wheel to the left by 90°.	Approx. +90 deg

OK or NG 

1. OK: Perform ABS actuator and electric unit (control unit) self-diagnosis again.
2. NG: Replace steering angle sensor and adjust neutral position of steering angle sensor. Refer to "ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION ".
