ABS indicator, brake system indicator, VSA indicator, and TSA warning do not come on at the same time

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.
