Thread: A hiccup with tailgate locking...

Some vehicles tend to lock their doors after being unlocked (by remote) if the drivers side door has not been opened within X amount of time. My range rover has not had a working fob in many many years so I can't recall if it did so to begin with, it does not do so when unlocked with the key.

The only reason I can think of in this case is that the door latch switch is not properly functioning or registering maybe? Regarding the rear, that indeed puzzles me for now. Not sure what is happening there but you might try to operate it by undoing the power plug from the servo and put 12v on it to see if it by any unforeseen chance has decided to stuff up at the exact moment you worked on the car Also, when the plug is removed put a voltmeter or small bulb on the other end and see what happens if you operate the button.

Cheers,

My L322 will relock itself in about a minute, if unlocked with the fob, but not opened.
Does P38 have a separate tailgate button on the fob, or require two unlock presses to unlock the tailgate?
Possibly the replaced lock has enabled the locking protocol to revert to its design parameters.

Ian, thanks for the thoughts. A separate pushbutton opens the top tailgate and then the bottom tailgate. I checked that the push button was intact and functioning. The wiring is intact without shorts apparent. it may well be a dud latch. I've also asked the supplier for their advice on the matter. We will see what happens.

Hi Pete, the drivers door latch you have fitted, is it new or second hand?
What was the locking doing prior to the new latch being fitted?
My first suspect is an issue with the latch itself, when they are faulty, they can cause all sorts of things to happen, doors locking and unlocking on their own, etc.
The tailgate button can cause issues with the tailgate not unlocking, but from what you describe, your issue seems to be central locking related.

Peter, I have contacted the supplier in Wales for their input. It was a used latch, so may well have an issue only they can solve! The previous behaviour was random locking and unlocking, waking of the BeCM, battery flattening/killing and all the other things that go with the expanded situation. Waiting now for a response, and we will see what happens next.

Thanks for your thoughts.

Pete, have you looked at the settings and checked for faults with a Nanocom or
IID?

If it were me, I'd be putting a new latch in, I'm suspecting the second hand latch is causing your issues.
I know they can be a bit pricey, but that will probably solve your problems.
I had similar symptoms with my door locks jumping up and down, it would lock and unlock itself randomly.
I fitted a new latch and all the problems went away immediately.
That was about 10 years ago now.
You might be lucky and they will refund you for the faulty item.
Hope you get it sorted!
Give Dave a call at british car components in Melbourne, he will get you sorted out with the correct item.

Pete,

I seem to recall that a tailgate latch earthing or supply runs from the driver's door latch. Have a look at the ETM and the answer might be in your question.
