VSA System Symptom Troubleshooting - ABS indicator, brake system indicator, VSA indicator, and TSA warning do not go off at the same time

ABS indicator, brake system indicator, VSA indicator, and TSA warning do not go off at the same time

1. Turn the ignition switch to LOCK (0).

1. 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 12 .

1. Disconnect the VSA modulator-control unit 47P connector.

1. Disconnect the yaw rate-lateral acceleration sensor 4P connector.

1. Disconnect the under-hood fuse/relay box connector D (10P).

1. 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, the yaw rate-lateral acceleration sensor, or the under-hood fuse/relay box.■
NO | - | Install the new No. 6 (7.5 A) fuse in the driver's under-dash fuse/relay box, then go to Step 7 .

1. Reconnect the VSA modulator-control unit 47P connector.

1. Reconnect the yaw rate-lateral acceleration sensor 4P connector.

1. Reconnect the under-hood fuse/relay box connector D (10P).

1. Turn the ignition switch to ON (II).

1. Check the ABS indicator, brake system indicator, VSA indicator, and the TSA warning for several seconds when the ignition switch is turned to ON (II).

Do the indicators come on then go off?

YES | - | Replace the VSA modulator-control unit. ■
NO | - | Troubleshooting is complete.■

1. Disconnect the VSA modulator-control unit 47P connector.

1. Turn the ignition switch to ON (II).

1. Measure the voltage between VSA modulator-control unit 47P connector terminal No. 8 and body ground.

Is there battery voltage?

YES | - | Go to Step 15 .
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.■

1. Turn the ignition switch to LOCK (0).

1. Check for continuity between VSA modulator-control unit 47P connector terminal No. 16 and body ground.

Is there continuity?

YES | - | Go to Step 17 .
NO | - | Repair open in the wire between the VSA modulator-control unit and body ground (G202).■

1. Disconnect the gauge control module 32P connector.

1. Check for continuity between the VSA modulator-control unit 47P connector terminal and gauge control module 32P connector terminal (see table).

   Sign | VSA Modulator-control Unit 47P Connector Terminal | Gauge Control Module 32P Connector Terminal
   --- | --- | ---
   CAN-L | No. 13 | No. 21
   CAN-H | No. 12 | No. 22

Is there continuity?

YES | - | Go to Step 19 .
NO | - | Repair open in the wire between the gauge control module and the VSA modulator-control unit.■

1. Reconnect all connectors.

1. Update the VSA modulator-control unit if it does not have the latest software. If the unit already has the latest software, substitute a known-good VSA modulator-control unit.

1. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.

1. Check the ABS indicator, brake system indicator, VSA indicator, and the TSA warning for several seconds when the ignition switch is turned to ON (II).

Do the indicators and warning 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. ■
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, then retest. If the VSA modulator-control unit was substituted, go to Step 1 .
