Doors

I have a funny problem. The driver and rear left door stoped openimg with a fob. I can still lock them with a fob but they will not open with a fob. Also if I try to lock and unlock the doors from inside with a pannel switch it has no effect what so ever on the driver door and rear left door but the other doors lock and unlock fine.

I find it odd that the problem is with diagonal doors and that they can be superlocked but not unlocked.

I would be greatful for any help. I checked the fuses incide passenger compartment but I have no idea why it's doing that.

If it is the motor in the doors why two motors in twodiaganal doors went falty together and why does it still lock with a fob.

PLEASE HELP.

I'm having a sort of similar problem with my 2000 L series. When I unlock the car from the squeeker then some doors, not always the same doors may not unlock. If I reapply the open command, then I can see the lock pins rise, reluctantly, as if they are mechanically sticking. I get the impression that is what the problem is in my case. All doors eventually unlock.

As for your problem it can either be a fault in the related door motors or, I believe that the central control unit can be programmed with different unlock sequences. Has this been fiddled with recently. If not it might be worth getting your garage to check and, possibly, reprogram the CCU to give you the required opening sequence.

Hope this helps.

Thanks Darmain,

Not sure why CCU would be involved. It just stopped working suddenly.
It is always the same two doors and they are never unlocked by the bob.
I can however lock them.

How would you check the CCU and how can you reprogamm it without having a computer plugged into it? If at all possible?

Of course there is nothing about that in any manual so would be greatful for your help.

THanks

I gather you can unlock them by mechanically operating the internal handle.

Drivers door, it is worth checking the wire loom unbilical from the door post to the back of the door. Sometimes the wires can stress fracture due to the repeated bending. I had this on the rear door.

Is the On side rear door also used a lot? Could be the same reason.

As I understand it the CCU can be programmed by the dealer (or a good independent garage) to either open all doors on first squeek, or to open the drivers door on the first squeek and the rest on the second squeek.

Another thing to try is, when you turn on the ignition the unlock motors should operate to ensure that all doors are unlocked for safety. This might be another CCU option but this is what happens on my Hippo. You should hear all the motors crank as you turn the key on. If yours does this, does it unlock these doors? If not then you are most likely looking at isolated door problems.

Probably the best thing to do is to get into the wire loom and volt test the signal to each doorway to verify the command is there, or not. Then you know if its in the doors or in the CCU.

Good luck

I know that it is possibleto have the main control unit programmed from new to :-

a. One press of key fob opens only drivers door
B. Second press unlocks remaining doors

OR

a. Single press opens all doors

You cannot reprogram this without the Testbook computer or something similar and expensive .

Can't think why you would have opposing doors unlocking - my passenger door is slow to unlock - the plunger is slow to raise - this is prob due to a weak lock solenoid in the door but at the moment I really can't be bothered to strip it - fed up after changing rear abs sensor and driveshaft oil seals!

It is possible for the electronics to go wrong or to lose settings. However, I don't know if the CCU can control all doors independently and I somehow doubt that it can, except if you consider the need for the left hand drive version. Drivers door gotta move then. I guess that would need a different wire loom anyway. The more I think about it the more I would tend to suspect a fault at the door locations rather than the CCU.

As I said before, you need to demonstrate if the unlock signal is getting to the door. If it is then its the door itself, if not its upstream to the controller.

Most cases like this it is the solenoid. On my vehicle the drivers door would lock, but not unlock. A new solenoid sorted the problem.

My rear passenger door stopped opening and this was solved by removing the inbdicator. (although I often have to press the plip a few times to encourage it)
