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

7. | Clear the DTCs using the HDS.

8. | Check the DTCs using the HDS. Doest the VSA and ABS indicators come on, and are DTC 22 indicated? YES - Check for loose or poor connections in the VSA control unit 46P connector. If connections are good, replace the VSA modulator-control unit.n NO - The system is OK at this time.n
