Diagnostic procedure

Step

Inspection

Action

1

INSPECT STEERING WHEEL FOR OFF-CENTER

•  Drive the vehicle and inspect the steering wheel position while driving in a straight line.

(See FRONT WHEEL ALIGNMENT [Australian Specs. and General (L.H.D., R.H.D.) Specs.]

No

Go to the next step.

2

INSPECT FOR IMPROPER INSTALLATION OF STEERING ANGLE SENSOR

•  Is the installation normal?

Yes

Go to the next step.

No

Repair installation or replace the steering angle sensor, then go to Step 4.

3

INSPECT STEERING ANGLE SENSOR

•  Inspect the steering angle sensor.
(See STEERING ANGLE SENSOR INSPECTION.)

•  Is the steering angle sensor normal?

Yes

Go to the next step.

No

Replace the steering angle sensor, then go to the next step.

(See COMBINATION SWITCH DISASSEMBLY/ASSEMBLY.)

4

VERIFY TROUBLESHOOTING COMPLETED

•  Make sure to reconnect all disconnected connectors.

•  Clear the DTC from the BCM memory using the M-MDS.
(See CLEARING DTC [BCM].)

•  Start the engine and drive the vehicle at 10 km/h {6.2 mph} or more.

•  Perform the BCM DTC inspection using the M-MDS.
(See DTC INSPECTION [BCM].)

•  Is the same DTC present?
