DTC 111

DTC 111: VSA-TCS Control Valve Actuator Relay
1. Check the VSA (40A) fuse in the under-hood fuse/relay box.
Is the fuse OK?
YES-Install the fuse, and go to step 2.
NO-Replace the fuse, and recheck. If the fuse is blown, check for a short to body ground in the wire between the under-hood fuse/relay box and the VSA fuse holder.
2. Check the VSA (20A) fuse (wire colors: BLU, PNK) in the VSA fuse holder.
Is the fuse OK?
YES-Install the fuse, and go to step 3.
NO-Replace the fuse, and recheck. If the fuse is blown, check for a short to body ground in the wire between the VSA fuse holder and the VSA control unit.
3. Check the VSA-TCS control valve actuator relay.
Is the relay OK ?
YES-With the relay removed, go to step 4.
NO-Replace the relay, and recheck.





4. Measure the voltage between the VSA-TCS control valve actuator relay 4P connector terminal No. 1 and body ground.
Is there battery voltage?
YES-Go to step 5.
NO-Repair open in the wire between the underhood fuse/relay box and the VSA-TCS control valve actuator relay.
5. Turn the ignition switch ON (II).





6. Measure the voltage between the VSA-TCS control valve actuator relay 4P connector terminal No. 4 and body ground.
Is there battery voltage?
YES-Go to step 7.
NO-Repair open in the wire between the fail-safe relay and the VSA-TCS control valve actuator relay.
7. Turn the ignition switch OFF.
8. Disconnect the VSA control unit connector A (22P).





9. Check for continuity between the VSA control unit connector A (22P) terminal No. 10 and the VSA-TCS control valve actuator relay 4P connector terminal No. 2.
Is there continuity?
YES-Go to step 10.
NO-Repair open in the wire between the VSA control unit and the VSA-TCS control valve actuator relay.
10. Disconnect the VSA control unit connector B (16P).





11. Check for continuity between the VSA control unit connector B (16P) terminal No. 12 and the VSA-TCS control valve actuator relay 4P connector terminal No. 3.
Is there continuity ?
YES-Go to step 12.
NO-Repair open in the wire between the VSA control unit and the VSA-TCS control valve actuator relay.





12. Check for continuity between the VSA control unit connector B (16P) terminal No. 12 and body ground.
Is there continuity?
YES-Repair short to body ground in the wire between the VSA control unit and the VSA-TCS control valve actuator relay.
NO-Go to step 13.
13. Install the VSA-TCS control valve actuator relay.
14. Connect all of disconnected connectors.
15. Do the neutral position memorization. Programming and Relearning
16. Test-drive the vehicle.
Does the VSA system indicator come on and is DTC 111 indicated?
YES-Check for loose VSA control unit connectors. If necessary, substitute a known-good VSA control unit, and recheck.
NO-The system is OK at this time.
