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" or "ST ANG SEN COM CIR" 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. Turn ignition switch OFF.
3. 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.





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.
5. CHECK STEERING WHEEL PLAY
Check 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.
