ABS indicator, brake system indicator, and VSA indicator do not go off

  1. Turn the ignition switch to LOCK (0).
  2. Check the No. 6(7.5 A) fuse in the driver's under-dash fuse/relay box.

    Is the fuse blown? 

    YES  -Replace the fuse. Turn the ignition switch to ON (II), then turn it to LOCK (0) again. If the fuse blows again, repair the short to body ground on the No. 6 (7.5 A) fuse circuit.

    NO  -Reinstall the checked fuse, then go to step 3.

  3. Check the No. 2-3 (30 A) fuse in the under-hood fuse/relay box.

    Is the fuse blown? 

    YES  -Replace the fuse. If the fuse blows again, repair the short to body ground on the No. 2-3 (30 A) fuse circuit.

    NO  -Reinstall the checked fuse, then go to step 4.

  4. Do the gauge control module self-diagnostic function (see SELF-DIAGNOSTIC FUNCTION ).

    Is the gauge control module OK? 

    YES  -Go to step 5.

    NO  -Replace the gauge control module (see GAUGE CONTROL MODULE REPLACEMENT ).

  5. Turn the ignition switch to LOCK (0).
  6. Disconnect the VSA modulator-control unit 47P connector (see step  4 on ).
  7. Turn the ignition switch to ON (II).
  8. Measure the voltage between VSA modulator-control unit 47P connector terminal No. 8 and body ground.

    Is there battery voltage? 

    YES  -Go to step 9.

    NO  -Repair an open in the wire between the No. 6 (7.5 A) fuse in the driver's under-dash fuse/relay box and the VSA modulator-control unit.

  9. Turn the ignition switch to LOCK (0).
  10. Check for continuity between VSA modulator-control unit 47P connector terminal No. 16 and body ground.

    Is there continuity? 

    YES  -Go to step 11.

    NO  -Repair an open in the wire between the VSA modulator-control unit and body ground (G202).

  11. Measure the voltage between VSA modulator-control unit 47P connector terminal No. 32 and body ground.

    Is there battery voltage? 

    YES  -Go to step 12.

    NO  -Repair an open in the wire between the No. 2-3 (30 A) fuse in the under-hood fuse/relay box and the VSA modulator-control unit.

  12. Disconnect the gauge control module 32P connector (see GAUGE CONTROL MODULE REPLACEMENT ).
  13. Check for continuity between the VSA modulator-control unit 47P connector terminal and gauge control module 32P connector terminal (see table).

    Is there continuity? 

    YES  -Go to step 14.

    NO  -Repair an open in the wire between the gauge control module and the VSA modulator-control unit.

  14. Reconnect all connectors.
  15. Update the VSA modulator-control unit if it does not have the latest software (see VSA MODULATOR-CONTROL UNIT UPDATE  ). If the unit already has the latest software, substitute a known-good VSA modulator-control unit (see VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION  ).
  16. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
  17. Check the ABS indicator, the brake system indicator, and the VSA indicator for several seconds when the ignition switch is turned to ON (II).

    Do the indicators come on then go off? 

    YES  -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 (see VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION  ).

    NO  -Check for loose terminals in the VSA modulator-control unit 47P connector. If the VSA modulator-control unit was updated, substitute a known-good VSA modulator-control unit (see VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION  ), then retest. If the VSA modulator-control unit was substituted, go to step  1.
