Is there battery voltage?
YES - Repair short to power in the wire between the VSA modulator-control unit and the wheel sensor. After repair, go to 7.
NO - Check for loose or poor connections in the VSA control unit 46P connector and wheel sensor 2P connector. If connections are good, replace the VSA modulator-control unit.n
