Go to Step 14 .
  1. Turn the ignition switch to LOCK (0).
  1. Substitute a known-good wheel speed sensor.
  1. Reconnect all connectors.
  1. Turn the ignition switch to ON (II).
  1. Check for DTCs with the HDS.
  1. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.

YES -
Go to Step 21 .
NO -
  1. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
  1. Check for DTCs with the HDS.
Is DTC 11-13, 13-13, 15-13, and/or 17-13 indicated?
YES -
Check for loose terminals in the VSA modulator-control unit 36P connector. If the VSA modulator-control unit was updated, substitute a known-good VSA modulator-control unit, then retest. If the VSA modulator-control unit was substituted, go to Step 1 .
NO -
If the VSA modulator-control unit was updated, troubleshooting is complete. If the VSA modulator-control unit was substituted, replace the original VSA modulator-control unit. If any other DTCs are indicated, go to the indicated DTCs troubleshooting.■
