NOTE: A wheel bearing that is installed backwards can cause this DTC.

1. Check all four tires.

Are all four tires the correct size and properly inflated?

YES - Go to step 2.

NO - Install the correct tires, a known-good set of tires, or set the tires to the correct pressure, and retest by test-driving.

2. Test drive the vehicle.
3. Check the RF, LF, RR, LR, WHEEL SPD in the VSA DATA LIST with the HDS.

Are all four the same indicated value?

YES - Go to step 4.

NO - Reinstall or replace the wheel speed sensor(s), and recheck by test-driving.

4. Check the magnetic encoders on the front wheel bearings and rear magnetic encoders on the hub bearing units.

Are they installed correctly and in good condition?

YES - Check for loose terminals in the VSA modulator-control unit 46P connector. Check for a loose connection at G202. If necessary, substitute a known-good VSA modulator-control unit and retest.

NO - Replace the front wheel bearing(s) or the rear hub bearing unit(s), and recheck by test-driving:

^ Front: Replace the front wheel bearing.
