Try disconnecting your battery cable and then reconnecting it.. if that doesn't work then you may have a faulty door sensor switch. this may be under factory warranty through the Chevy dealership

Hi I have a 2006 Lincoln navigator the air suspension pump will not turn on the vehicle dynamics module is not turning on the pump relay because in the pid data the drivers door says it is ajar when it is...


Hey Jeff, any U- codes stored in any modules ?
U1900 Missing CAN message(s) Door(s) ajar, PRNDL, 4x4, instrument cluster (IC), running boards, vehicle speed REFER to Section 418-00 . U2023 Invalid CAN message(s) Door(s) ajar, PRNDL, 4x4, instrument cluster (IC), running boards, vehicle speed REFER to Section 418-00 .
L4 CHECK THE VDM FOR DOOR AJAR INPUT
  • Key in ON position.
  • Monitor VDM door position status PID.
  • Close all doors, liftgate, liftgate glass and power running boards.
  • While observing the diagnostic tool, open and close one door.
  • Does the door status PID change between CLOSED and AJAR states?
When you open an close the driver door you have no PID change ,right ?

The door ajar input is an input to the Vehicle Security Module , then transmitted over the bus ! You'll have to find a diagram for the med. speed CAN data bus .

2008 explorer door locks not locking from door switches


This is not a good thing. Ford uses a computer called the GEM and that means General Electronics Module. It controls:
  • Low Coolant Indicator On Cluster
  • Brake Indicator on Cluster
  • DRL - Control
  • Wipers
  • AutoLamps
  • Rear Defrost
  • Interior Lamps(dome)
  • High Beam Indicator only (cluster)
  • Low Coolant indicator
  • Key-in Buzzer
  • Seatbelt indicator only (Cluster)
  • Trunk Pop Relay
  • Power Locks
  • Door Ajar Sensors
  • Door Keyless entry pad
  • Remote Keyless Entry
  • One Touch Down (power window)
  • Air Bag Tone
  • Anti Theft (perimeter Alarm) (SEL, or SE(s) with mods)
  • Lift gate ajar (wagon)
  • Liftgate Pop
  • Accessory Delay signal (accessory that work after engine off, prior to door ajar)
  • Battery Saver Relay signal (accessory that work after engine off, 15 mins) Map lights, vanity mirrors

They are located behind the radio in the dash and they are $$$ about 600 USD.

Door ajar message on my 2008 ford edge


open the door and manually press in the little switch that the door closes onto. If the door open light stays on then there is probably water got into the back of the switch or dirt ... giving a false signal to the dash light. try cleaning the switch and contacts.

Door contact shows door ajar


If the door is closed and you still get the door ajar message then chances are the plunger in the door frame is bad. The plunger is the little switch that pushes in when the door closes and opens with te door. you can push it in and out with your finger to test it.

Rear access door ajar


What's your question ? Tailgate ajar light lit on the instrument cluster ?
The Body Control Module (BCM) monitors the lift glass and the cargo door ajar switches. When the switch closes, the path to ground is completed, and the BCM sends a class 2 message to the instrument cluster to display the CARGO DOOR AJAR message.There are two ajar switches for the rear door ,a left an a right ,the third switch is for the lift glass ajar switch . All three of these switches splice pack SP410 At ground point G410

(Shouldn't have any readings when door(s) and/or window closed.) It's the opposite . switches are open with door closed , G410
In the Body Harness, Behind the RR quarter trim panel near the D-Pillar
It turns out it has nothing to do with rear door. Something about drivers door actuator. NO IT DOESN"T !!!!

Instrument cluster indicates door ajar but there is not


The door latch has a switch built into it to replace the old door jamb switch. If the switch is faulty the system will think the door is ajar. A scanner will show an open switch.

YOU SHOULD BE UNDER WARRANTY.

My passenger's door open indicator is on but the door is closed. Where is the indicator located? 2005 freestar. Thanks


Normal Operation When any door or the liftgate is opened, the ajar switch provides a ground signal to the smart junction box (SJB). When the door or liftgate is closed, the ajar switch opens, removing the ground signal. The SJB uses the multiple inputs from the ajar switches to determine whether the doors or the liftgate are in the open or closed position. The SJB then provides a message to the instrument cluster over the communication network. The message center uses this information to display the door/liftgate ajar message.

I suspect your door switch is not closing all the way.

"Door Ajar" signal on dash panel stays on even when doors are clo


there should be a switch mounted( or more than one) in the door jamb that tells the car when the car door is open...i will probably look like a little plastic plunger...might be broken off or bad internally

Sliding door switch?


Do you know anything about automotive electronics ?
All courtesy lamps are controlled by the generic electronic module (GEM).
The four contacts are not switches , the part you want to replace is the door ajar switch . The door ajar switch is inside the door part of the lock actuator . Those contacts just allow circuit continuity when the door is closed , when you open the door continuity is broken or open . The GEM now know the door is open an will now turn on the dome lights . The door ajar switches stick , try spraying WD-40 into the door latch ,open an closing the latch . If this doesn't fix the problem you will need to take the inside door trim panel off and replace the ajar switch .
