Passenger door locked - 2006 Jaguar XJ8

Pull the door panel apart and check and see if the pun that locks and unlocks the door is connected, if so check the power supply the the actuator.

The locks on your vehicle are electronically controlled by the BCM - body control module . The driver an passenger door switche's are input's to the BCM . Do you know anything about automotive electronic's ? anti theft alarm remote, could this be part of the problem , No it's just a key less entry remote , nothing to do with the anti-theft .
Door Lock System Components
The Power Door Lock System consists of the following components:
• Body control module (BCM)
• Driver door lock switch
• Front passenger door lock switch
• Door lock actuators in each of the doors
• IBCM (PWR) 15-amp fuse

Door Lock System Controls
The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:
• A door lock switch Lock or Unlock actuation
• A keyless entry transmitter actuation
• An automatic door lock actuation
• An automatic door unlock actuation
• A last door closed locking (LDCL) actuation

Driver and Passenger Door Unlock Operation w/o Keyless Entry
When the body control module (BCM) detects a transition of either of the door lock switches to the Unlock position, it switches the door lock actuator unlock control circuits to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the driver passenger door lock actuators transition to the Unlock position.

Your best bet , take your vehicle to a qualified repair shop ! Need special tool to diagnose .

Power Door Locks Inoperative

Install a scan tool.
Turn ON the ignition, with the engine OFF.
With a scan tool, observe the door lock switch parameter in the Doors data list.
Does the scan tool display Idle?
YES - Go to Step 4
NO - Go to Step 8
4
Activate the driver door lock switch to the LOCK and UNLOCK positions.
Does the scan tool display Idle?
YES - Go to Step 9
NO - Go to Step 5
5
Activate the front passenger door lock switch to the LOCK and UNLOCK positions.
Does the scan tool display Idle?
YES - Go to Step 9
NO - Go to Step 6
6
With a scan tool, observe the driver door lock actuator command and the passenger door lock actuator command parameters in the Doors data list.
Activate a door lock switch to the LOCK and UNLOCK positions.

Sounds like the main wiring loom into the door has been damaged.
Check near the hinges, where the door swings, to see if any damaged wires. Does the door lock and unlock from the drivers side switch?

this is a problem that can appear after your car battery died, cause the car didn't reset propely, so taking the battery out and putting it back in or letting your car die again would do the trick. I tried a lot of reprogramming procedured for my remote key, none of them worked, what did the trick though was simply unlocking the doors via the all door unlock button on the passenger side door, so simple.

faulty master switch ..replace

looks like car has other issues as well.. but try that first

Sounds like the locking mechanism in the passenger door may need lubrication. You could also have a wiring issue and/or the actuator solenoid on that door could be bad. I'm assuming you are using the keyless locking fob. What happens when you push the door locking button on the driver's side door or the locking button on the passenger door itself? If these work as they should and with not hesitation then you likely have some other problem in the locking system.

hi, does the drivers door unlock and lock all the other doors if it does then you may find that a clip or connecting bar has come off the passenger door lock, you would need to take the door panel off to check,

If how ever the passenger door dont lock and unlock via the drivers door then you would need to buy a new central locking motor for the passenger door..

Your best option would be to remove the passenger side door panel and get someone to lock and unlock the drivers door whilst you look at the passenger side and have a look to see what parts are moving this should then give you a good idea of the parts that could be damaged

If the driver door control operates all of the other doors locks correctly then its the switch on the passenger door thats defective . Because the driver control supercedes all other controls. But if the driver door does not operate the passenger door lock then its the passenger door motor/solnoid.

The door lock/unlock input from the driver's key switch goes to the Door Multiplex control unit (main switch), the Door multiplex control unit then sends a signal on the BUS (CAN) circuit to the passenger's multiplex control unit; the passenger's multiplex control unit then controls all the door locks. The passenger's door lock key switch inputs to the passenger's multiplex control unit, if the locks work from the passenger's side key switch but not the driver's side key switch, the most likely cause is the driver's multiplex control unit (main switch) not sending the signal to the passenger's side multiplex control unit. This could also be the drivers side door lock actuator. Hope this helps!

Sounds like bad wiring, or bad door lock actuators. Check for power while locking/unlocking the doors.
