Hi guys can anyone help, I have a Freelander 2 and I am unable to lock the doors as it thinks the passenger door is open, I have tried unplugging the door module and removing the multiplug going to the door latch/motor but the warning is still on the dash, I removed the battery cable for 20 minutes also, I even tried removing the fuse, Think this one is over my head and I need some help, Has anyone heard of this before? Thanks in advance.

Hi Have you tried sitting in the car starting the engine then pressing the lock button so all doors lock, then turn engine off get out of the car then fob lock only the drivers door, see what happens it may reset the locking system.
Hi, Thanks for your quick response, If I'm sitting in the car and start the engine then press the button on the dash to lock the doors, they all close then immediately re-open again I can't get the doors to lock because the car thinks the passenger door is open, I can't get the warning on the dash to go away so my doors now remain open until I can get a fix for this, It's really weird I don't know if it could be ECU related or not.
There's a door latched switch in the door lock assembly. It sounds like the door module is seeing that switch as open, so it won't locks the doors as a result.
I think the door latch is where the fault lies, more so than the door module anyway.

Unplugging the door module would upset the CJB, and would likely default to issuing a door open signal, simply because it couldn't prove otherwise.
Unplugging the door latch assembly, would likely have the same result, simply because the door couldn't be proved as closed. These integrated car monitoring systems must assume the safest strategy, in the event of missing information, in this case its safer to assume the door is open, even if its not.
Have to read the codes from the door modules or CJB?
Yes, you'll need to either buy a suitable diagnostic reader, or pay to have the codes read. It's actually sensible to buy a decent multi-system code read for these vehicles, as they're electronically really complicated. There are around 20 separate modules in communication with each other, on one or more of different types of data bus.
So if you plan to do your own repairs, a code reader is a must.
