8. Check for continuity between the appropriate VSA modulator-control unit 46P connector terminals and steering angle sensor 5P connector terminals respectively (see table).





Is there continuity?

YES - Go to step 9.

NO - Repair open in the wire between the VSA modulator-control unit and the steering angle sensor.

9. Substitute a known-good steering angle sensor.
