Steering Angle Sensor System
INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSIS RESULT
Check self-diagnosis results.





Is above displayed in self-diagnosis item?
YES >> GO TO 2.
NO >> Inspection End.

2. CHECK CONNECTOR
1. 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.
2. Reconnect connectors and repeat ABS actuator and electric unit (control unit) self-diagnosis.
Is ST ANGLE SEN CIRCUIT displayed?
YES >> GO TO 3.
NO >> Inspection End.

3. CHECKING STEERING ANGLE SENSOR POWER AND GROUND








1. Check voltage between steering angle sensor harness connector M47 and body ground.








2. Check resistance between steering angle sensor harness connector M47 and body ground.
OK or NG
OK >> GO TO 4.
NG >> Repair the circuit.

4. CHECK STEERING ANGLE SENSOR HARNESS
1. Check CAN communication system. Refer to CAN COMMUNICATION.
2. Turn ignition switch OFF and 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.

5. CHECK STEERING WHEEL PLAY
Check steering wheel play. Refer to CHECKING STEERING WHEEL PLAY.
OK or NG
OK >> GO TO 6.
NG >> Adjust steering wheel play.

6. CHECK DATA MONITOR
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.
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.
