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-55, "Wiring Dia-

gram"

.

Is the inspection result normal?

YES (Present error)>>Replace the steering angle sensor. Refer to 

BRC-137, "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.
