VSA activation indicator does not come on at start-up (bulb check)

Diagnostic procedure

1. Do the gauge control module troubleshooting.
2. Update the VSA modulator-control unit if it does not have the latest software, or substitute a known-good VSA modulator-control unit, then retest. If it is OK, 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.
