2.
CHECK HARNESS FOR OPEN CIRCUIT
1. Disconnect the connector of steering angle sensor.
2. Check the resistance between the steering angle sensor harness connector terminals.
Is the measurement value within the specification?
YES
>> GO TO 3.
NO
>> Repair the steering angle sensor branch line.
3.
CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the steering angle sensor. Refer to
BRC-215, "Wiring Diagram - Sedan"
Is it normal?
YES (Present error)>>Replace the steering angle sensor. Refer to
BRC-242, "Removal and Installation"
.
YES (Past error)>>Error was detected in the steering angle sensor branch line.
NO
>> Repair the power supply and the ground circuit.
