Keyless/Power Door Locks/Security System Symptom Troubleshooting - Doors automatically relock 30 seconds after being unlocked with the keyless remote even though a door has been opened

NOTE:  Before troubleshooting, check the B-CAN DTCs. If any DTC is indicated, troubleshoot the indicated DTC first.

• 1. Determine possible failure area (MICU, others):

  - 1. Move the interior light switch to the DOOR position.

  - 2. Turn the vehicle to the OFF (LOCK) mode.

  - 3. Watch the front individual map light and the door/tailgate indicators on the gauge control module.

  Do the individual map light and door/tailgate indicators come on when the door/tailgate is open, and go off when the door/tailgate is closed?

  YES 

  Faulty MICU; replace the under-dash fuse/relay box .

  NO 

  Go to step 2.

• 2. Open wire check (DR DOOR SW, AS DOOR SW, RR DR DOOR SW, RR AS DOOR SW, TRUNK SW lines):

  - 1. Disconnect the following connectors.

  Under-dash fuse/relay box connector B (44P) Each door switch 1P connector Power tailgate closer unit connector B (6P)*1 Tailgate latch switch 4P connector*2 *1: With power tailgate *2: Without power tailgate

  - 2. Check for continuity between test points 1 and 2.
