Lights come back on randomly after being turned off by removing ignition key and opening passenger door

Driver door switch ,ajar switch . This switch is a input to the BCM - body control module .
Retained Accessory Power Description and Operation
Retained accessory power (RAP) is a vehicle power mode that permits the operation of selected customer convenience items after the ignition switch is turned OFF. These selected items will remain in operation until a passenger compartment door or liftgate is opened or until the RAP function timer reaches its shut-off limit.
The class 2 RAP power mode is mapped to GMLAN serial data circuit as Off Awake power mode. Refer to Data Link Communications Description and Operation for more information on data link communications. The BCM monitors the ignition switch signals, battery condition and the doors status to determine whether RAP should be initiated. The modules that support the RAP power mode will operate the systems under their control as required by their RAP power mode strategy.
RAP will end when one of the following conditions is met:
• The BCM detects the opening of a passenger compartment door.
• The RAP timer expires.
• The battery capacity decreases below a prescribed limit.
• Any other ignition switch state is chosen.
The function supported in the RAP power mode is the operation of the radio.

It would go off on it's own in ten min.

try this it may work put key in ignition and turn to number 2 ( lights on dash) press the fob button on the key. doors should lock, then turn back off to 0, then press the fob button again the doors should open then try to start engine. if all works again but the alarm keeps going off randomly, the power sounder battery may be flat, it can be charged when the system is working again. but sometimes it can get damaged. and it may need to be changed. as I dont know what the sound is coming from under you hood Im thinking it could be this.

2005 CTS 3.6 Dead battery, key stuck, service anti theft and nothing happens when you turn key, Ttried everything, ECM reset, key memory reset, charged battery to 12.7 volts, locked door w remote and opened w key, anyway you get the idea. After 3 days of online reading and trying, THIS IS WHAT WORKED, 1. put key into on position 2. removed sarter relay from front fuse panel 3. jumped 1st pin closest to fender and passenger seat with pin that is closest to motor and front fender. I used a paper clip and just made contact long enough for car to start. ran car for five minutes and took key out and everything went back to normal. then I took car to advance auto parts to have engine light reset. if car does not go back to normal you have ECM (car computer) failure. video on YouTube under "no crank, no start"

This chime is also the same chime used for the doors. To remove this you will also be losing the ignition chime when the keys are in the ignition or when the doors open.
It can be removed simply by unplugging it. Just open the door with the keys in the ignition, look under the dash on the driver or passenger side. using you good hearing locate the chime and simply disconnect the plug from the back.

you might be able to reprogram the key, but you can only do this if you have two keys, what you need to do is put one key in the ignition turn the ignition on ( not over ) put the key that needs reprogramming into the drivers door and lock the vehicle with the key not the button, wait 10 seconds, remove the key, then press the unlock on the fobb, turn ignition off, remove key from ignition, put in the key that you just unlocked the car with and turn ignition do not turn over, turn off ignition,remove key wait 10 seconds, then put key back in then you should be able to turn it over as normal, if that does not work you will have to take key to be reprogramed at the main dealer...hope this helps

I would suspect you have a bad door switch on one of the doors or liftgate. They are usually plunger switches. Try pusing them in one at a time and see f the lights go out. Hold it in long enough to account for the time delay.

please rate if this helps you.

Generic Electronic Module (GEM)/Central Timer Module (CTM) Controlled Functions
The generic electronic module (GEM) is equipped on four-wheel drive vehicles with power windows. The central timer module (CTM) is equipped only on two-wheel drive vehicles without power windows.
NOTE: GEM/CTM diagnostics are compatible with New Generation STAR (NGS) Tester.
The GEM/CTM incorporates the functions of several different modules into one, and offers diagnostics to easily locate and repair concerns affecting the subsystems that it controls.
The GEM/CTM constantly monitors the systems under its control and reports a concern in the form of a diagnostic trouble code (DTC). A DTC can be retrieved with NGS Tester through the communication link.
NGS Tester is a menu-driven tester that allows the user to run specific tests. NGS Tester can isolate faults in the GEM/CTM subsystems through a symptom-driven diagnostic procedure. Connecting NGS Tester to the GEM/CTM communication link will not alert the GEM/CTM. If the GEM/CTM is "asleep" when the diagnostic connector is plugged in, the GEM/CTM must be "awakened". If the communication link cannot be established, it is advised to turn the ignition to RUN.
NOTE: The GEM/CTM has a sleep function to minimize battery consumption. During the sleep mode, the GEM/CTM turns off all outputs and monitors only the following:

• Door ajar (driver door, passenger door, liftgate, LH rear and RH rear doors).
• Key-in-ignition.
• Key in RUN or ACC.
• Two-step unlock switch (unarm switch).
• Digital TR sensor.
• Illuminated entry request (remote anti-theft personality [RAP] module).

If a change of status occurs at one of these inputs while the GEM/CTM is asleep, the GEM/CTM will "wake up." When the GEM/CTM awakens, it performs an internal self-test, and begins normal operation. At this point, the GEM/CTM will have all of its functions operational.
The GEM/CTM will go into the sleep mode immediately after both of the following conditions have been met:

• Key in OFF or key not in ignition.
• After 45 minutes with no change in any wake-up input.

The GEM/CTM control system has two modes of operation; the normal operating mode and the tester-dependent diagnostics mode.
The normal operation of the GEM/CTM can detect errors. An integral part of the normal GEM/CTM operation is the continuous diagnostic capability. Continuous diagnostics detects errors and changes the GEM/CTM control strategy. There is no warning lamp for the GEM/CTM; therefore, a DTC concern will direct you to the GEM/CTM. Examples of faults that may be detected during normal operation include:
NOTE: The GEM/CTM can only detect open circuit/short to GRD faults when the GEM/CTM in not energizing a load, and short to battery faults when the GEM/CTM is attempting to energize a load.

• GEM/CTM continuous self-test (RAM, ROM, EEPROM, A/D checking).
• Output driver monitoring (open circuit/short to ground [GRD], short to power).

• Illogical combinations of input signals.

Here's what I suspect is happening. The door locks will lock and unlock normally when the key is OUT of the ignition. If the key is IN the ignition, the doors cannot be locked (manually, key fob, or otherwise, if the system is operating as designed - prevents the doors being locked when the key is in the ignition). I've seen this problem before, but on a Santa Fe, not an Accent. The ground signal of the right hand front passenger door was lost, and the doors automatically locked. Perhaps something similar is happening in the circuit between the ETACS module and the right front passenger door lock/unlock actuator. Could be anywhere in the circuit.




These wiring diagrams may be helpful. The relays expecially may help solve this issue. As you can see, these relays are also controled by the ETACS module (Remote Keyless Entry).

when you open the power sliding doors the turn signal lights are supposed to flash. are there other lights that flash?

sounds like the door ajar switch is defective.

If you can't turn the key all the way to start, you need either a lock cylinder or an ignition switch...maybe both.
