VSA 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.
    1. Is the fuse OK? 
    2. YES  - Go to step 2.
    3. 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.

    1. Is there battery voltage? 
    2. YES  - Go to step 5.
    3. 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.

    1. Is there continuity? 
    2. YES  - Go to step 7.
    3. NO  - Repair open in the wire between the VSA control unit and body GS 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.

    1. Does the VSA system indicator go off? 
    2. YES  - Check for loose terminals in the VSA control unit connectors. If necessary, substitute a known-good VSA control unit, and recheck.
    3. NO  - Go to step 9.
  9. Connect gauge assembly connector A (30P) terminal No. 20 and body ground with a jumper wire.

    1. Does the VSA system indicator go off? 
    2. YES  - Repair open in the wire between the VSA control unit and the gauge assembly.
    3. 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.
