Inspection Procedure

Check self-diagnosis results.

Is above displayed in self-diagnosis item? 

• YES: GO TO 2.
• NO: Inspection End.

1. Turn ignition switch OFF.
2. Disconnect steering angle sensor connector M47 and ABS actuator and electric unit (control unit) connector E125 and check terminals for deformation, disconnection, looseness, or damage. Repair or replace as necessary.
3. Reconnect connectors and repeat ABS actuator and electric unit (control unit) self-diagnosis.

Is "ST ANGLE SEN CIRCUIT" or "ST ANG SEN COM CIR" displayed? 

• YES: GO TO 3.
• NO: Inspection End.

1. Turn ignition switch ON.
2. Check voltage between steering angle sensor harness connector M47 and body ground.

OK or NG 

• OK: GO TO 4.
• NG: Repair the circuit.

1. Check CAN communication system. Refer to CAN COMMUNICATION SYSTEM DESCRIPTION .
2. Disconnect steering angle sensor connector M47 and ABS actuator and electric unit (control unit) connector E125.
3. Check continuity between ABS actuator and electric unit (control unit) connector E125 and steering angle sensor connector M47.

OK or NG 

• OK: GO TO 5.
• NG: Repair or replace harness.

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

OK or NG 

• OK: GO TO 6.
• NG: Adjust steering wheel play.

1. Connect steering angle sensor and ABS actuator and electric unit (control unit) connectors.
2. Use "DATA MONITOR" to check if the status of "STR ANGLE SIG" is normal.
   DATA MONITOR DESCRIPTION
   
   

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

OK or NG 

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