VSA System Indicator Does Not Go Off
VSA System Indicator Circuit TroubleshootingVSA system indicator does not go off
1. Check the ECU (15A) fuse in the driver's under-dash fuse/relay box, and reinstall the fuse if it is OK.
Is the fuse OK?
YES-Go to step 2.
NO-Replace the fuse, and recheck. If the fuse is blown, check for a short to body ground in this fuse circuit. If the circuit is OK, check for loose VSA control unit connectors. If necessary, substitute a known-good VSA control unit, and recheck.
2. Disconnect VSA control unit connector C (26P).
3. Turn the ignition switch ON (II).
4. Measure the voltage between VSA control unit connector C (26P) terminal No. 1 and body ground.
Is there battery voltage?
YES-Go to step 5.
NO-Repair open in the wire between the VSA control unit and the driver's under-dash fuse/relay box.
5. Turn the ignition switch OFF.
6. Check for continuity between VSA control unit connector C (26P) terminal No. 14 and body ground.
Is there continuity?
YES-Go to step 7.
NO-Repair open in the wire between the VSA control unit and body ground (G402).
7. Turn the ignition switch ON (II).
8. Connect VSA control unit connector B (16P) terminal No. 1 and body ground with a jumper wire.
Does the VSA system indicator go off ?
YES-Check for loose terminals in the VSA control unit connectors. If necessary, substitute a known good VSA control unit, and recheck.
NO-Go to step 9.
9. Connect gauge assembly connector A (30P) terminal No. 20 and body ground with a jumper wire.
Does the VSA system indicator go off ?
YES-Repair open in the wire between the VSA control unit and the gauge assembly.
NO-Check for loose terminals in gauge assembly connector A (30P). If the connector is OK, replace the printed circuit board in the gauge assembly.
