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

Doors automatically relock 30 seconds after being unlocked with the remote even though a door has been opened

NOTE:

	Refer to the Electrical Wiring Diagrams for the location of the under-dash fuse/relay box connectors.
	Before troubleshooting, check the B-CAN DTCs. If any DTC is indicated, troubleshoot the indicated DTC first.

Determine possible failure area (MICU, others):

Determine possible failure area (MICU, others)

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

?2.	Press the engine start/stop button to select the OFF mode.

?3.	Watch the individual map light and the door indicators on the gauge control module.

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


	YES

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


	NO

Go to step 2.

Open wire check (FL DOOR SW, FR DOOR SW, RL DOOR SW, RR DOOR SW, TRUNK SW lines):

Open wire check (FL DOOR SW, FR DOOR SW, RL DOOR SW, RR DOOR SW, TRUNK SW lines)

?1.

Disconnect the following connectors.

Under-dash fuse/relay box connector D (44P)
Under-dash fuse/relay box connector S (18P)
Each door switch 1P connector
Trunk lid latch switch 3P connector

?2.

Check for continuity between test points 1 and 2 respectively.

Is there continuity?


	YES

The FL DOOR SW, FR DOOR SW, RL DOOR SW, and RR DOOR SW wires are OK. Replace the bad door switch.?


	YES

The TRUNK SW wire is OK. Faulty trunk lid latch switch or GND line, go to step 3.


	NO

Repair an open or high resistance in the wire between the MICU and the door switch/trunk lid latch switch.?

Open wire check (GND line):

Open wire check (GND line)

?1.

Check for continuity between test points 1 and 2.

Test condition	IG LOCK (0) or OFF mode Under-dash fuse/relay box connector D (44P): disconnected Under-dash fuse/relay box connector S (18P): disconnected Each door switch 1P connector: disconnected Trunk lid latch switch 3P connector: disconnected
Test circuit	GND
Test point 1	Trunk lid latch switch 3P connector No. 2 (BLK)
Test point 2	Body ground

Is there continuity?


	YES

The GND wire is OK. Faulty trunk lid latch switch; replace the trunk lid latch.?


	NO

Repair an open or high resistance in the ground wire or poor ground (G603).?
