INSPECTION PROCEDURE

1.SELF-DIAGNOSIS RESULT CHECK
Check self-diagnosis results.





Is the above displayed in the self-diagnosis display items?
YES >> GO TO 3.
NO >> GO TO 2.

2.DATA MONITOR CHECK

3.CONNECTOR INSPECTION
1. Disconnect the ABS actuator and electric unit (control unit) connector E125 and steering angle sensor M47.
2. Check the terminals for deformation, disconnection, looseness or damage.
OK or NG
OK >> GO TO 4.
NG >> Repair or replace as necessary.

4.CHECKING STEERING ANGLE SENSOR POWER AND GROUND
1. Turn the ignition switch ON.








2. Check voltage between steering angle sensor connector M47 and ground.








3. Check resistance between steering angle sensor connector M47 and ground.
OK or NG
OK >> Check the CAN communication system. Refer to BRC-39, "CAN Communication System Inspection". CAN Communication System Inspection
If the CAN communication system is OK, replace spiral cable (steering angle sensor) and adjust neutral position of steering angle sensor. Refer to BRC-45, "Adjustment of Steering Angle Sensor Neutral Position". Testing and Inspection
NG >> Repair the circuit.
