ABS indicator, brake system indicator, and VSA indicator do not go off
- Turn the ignition switch to LOCK (0).
- Check the No 6 (7 5 A) fuse in the driver's under-dash fuse/relay box
Is the fuse blown?
YES -Go to step 3
NO -Reinstall the checked fuse, then go to step 10
- Disconnect the VSA modulator-control unit 47P connector (see step 4 on page 19-104)
- Disconnect the yaw rate-lateral acceleration sensor 4P connector (see YAW RATE-LATERAL ACCELERATION SENSOR REPLACEMENT )
- Check for continuity between VSA modulator-control unit 47P connector terminal No 8 and body ground

Is there continuity?
YES -Repair short to body ground 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 or the yaw rate-lateral acceleration sensor
NO -Install the new No 6 (7 5 A) fuse in the driver's under-dash fuse/relay box, then go to step 6
- Reconnect the VSA modulator-control unit 47P connector
- Reconnect the yaw rate-lateral acceleration sensor 4P connector
- Turn the ignition switch to ON (II)
- 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 -Troubleshooting is complete
NO -Replace the VSA modulator-control unit (see VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION )
- Disconnect the VSA modulator-control unit 47P connector (see step 4 on page 19-104)
- Turn the ignition switch to ON (II)
- Measure the voltage between VSA modulator-control unit 47P connector terminal No 8 and body ground

Is there battery voltage?
YES -Go to step 13
NO -Repair 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
- Turn the ignition switch to LOCK (0)
- Check for continuity between VSA modulator-control unit 47P connector terminal No. 16 and body ground

Is there continuity?
YES -Go to step 15
NO -Repair open in the wire between the VSA modulator-control unit and body ground (G202)
- Disconnect the gauge control module 32P connector
- Check for continuity between the VSA modulator-control unit 47P connector terminal and gauge control module 32P connector terminal (see table)VSA MODULATOR-CONTROL UNIT TERMINAL REFERENCE

Is there continuity?
YES -Go to step 17
NO -Repair open in the wire between the gauge control module and the VSA modulator-control unit
- Reconnect all connectors
- 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 )
- Turn the ignition switch to LOCK(0), then turn it to ON (II) again
- 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
