## VSA System Indicator Circuit Troubleshooting

### VSA system indicator does not come on

1. | Turn the ignition switch OFF.

2. | Remove the gauge assembly.

3. | Disconnect the gauge assembly connector A (20P).

4. | Turn the ignition switch ON (II).

5. | Measure the voltage between body ground and gauge assembly connector A (20P) terminal No. 2. Is there battery voltage? YES - Go to 6. NO - Repair open in the wire between gauge assembly and under-dash fuse/relay box.n

6. | Turn the ignition switch OFF.

7. | Check for continuity between the gauge assembly connector A (20P) terminal No. 9 and body ground. Is there continuity? YES - Go to 8. NO - Repair open in the wire between gauge assembly and body ground (G401).n

8. | Disconnect the VSA control unit 46P connector.

9. | Disconnect the gauge assembly connector C (40P).

10. | Check for continuity between the gauge assembly connector C (40P) terminal No. 30 and the gauge assembly connector A (20P) terminal No. 9. Is there continuity? YES - Repair short to body ground in the wire between the VSA modulator-control unit and the gauge assembly.n NO - Check for loose or poor connections in the gauge assembly connectors. If connections are good, replace the gauge assembly.n

### VSA indicator does not go off, and no DTCs are stored

1. | Check for loose or disconnected connection in the VSA control unit 46P connector. Is the connected properly? YES - Go to 2. NO - Connect the VSA control unit 46P connector properly, and recheck.n

2. | Turn the ignition switch OFF.

3. | Check the No. 25 (7.5 A) fuse in the under-dash fuse/relay box, and reinstall the fuse if it is OK. Is the fuse OK? YES - Go to 4. NO - Replace the fuse, then go to 13.

4. | Disconnect the VSA control unit 46P connector.

5. | Turn the ignition switch ON (II).

6. | Measure the voltage between body ground and VSA control unit 46P connector terminal No. 40. Is there battery voltage? YES - Go to 7. NO - Repair open in the wire between the VSA control unit 46P connector and under-dash fuse/relay box.n

7. | Check for continuity between body ground and the VSA control unit 46P connector terminals No. 40. Is there continuity? YES - Go to 8. NO - Repair open in the wire between the VSA control unit 46P connector and body ground (G202).n

8. | Turn the ignition switch OFF.

9. | Remove the gauge assembly.

10. | Check for loose or disconnected connection in the gauge assembly connector C (40P). Is the connected properly? YES - Go to 11. NO - Connect the gauge assembly connector C (40P) properly, and recheck.n

11. | Connect the gauge assembly connector C (40P) terminal No. 30 and body ground with a jumper wire.

12. | Turn the ignition switch ON (II), and watch the VSA indicator. Does the VSA indicator does not come on? YES - Replace the VSA modulator-control unit.n NO - Do the gauge assembly self-diagnosis function.n

13. | Turn the ignition switch ON (II), and watch the VSA indicator. Does the VSA indicator come on, then go off after several seconds? YES - The system is OK at this time.n NO - Go to 14.

14. | Turn the ignition switch OFF.

15. | Disconnect the VSA control unit 46P connector and remove the No. 25 (7.5 A) fuse in the under-dash fuse/relay box.

16. | Check for continuity between body ground and the VSA control unit 46P connector terminals No. 9. Is there continuity? YES - Repair short to body in the wire between the VSA control unit 46P connector and under-dash fuse/relay box.n NO - Check for loose connector terminals in the VSA control unit 46P connector and repair if necessary. If terminals are OK, replace the VSA modulator-control unit.n
