Remote Central Locking conversion.

Any electrical issues

It is tight, even if you solder - not a lot of movement - though you can remove some of the tape binding the loom to free it up a little.

Hi

I read through the instructions again this evening with the intention of making a start with the remaining wiring. However I must admit I do not understand the procedure for identifying the lock and unlock wires. I then ran out of time and unfortunately I am going on holiday from tomorrow until 27 August. I am not losing interest in the project and I am keen to complete it, I appreciate your help, but time is the problem. I will contact you on my return for some more advice.

Regards

Sure, no problem. You can always give me a call and I can explain on the phone instead when you come back. Enjoy your holidays!!

Hi Cliff

Back from a very enjoyable holiday.

I have attached a .pdf file which includes a circuit diagram and some questions. I hope you can read it.

Thanks again for your help.

Hi!

I can read it perfectly, nice clear diagram and you have understood what I wrote - confirm that 12v, 0v, 2*COM and NO are all correctly assigned.

To your questions:

"IN THE UNLOCKED SITUATION WHAT SHOULD BE THE VOLTAGE ON THE LOCK AND UNLOCK WIRES. IN THE LOCKED SITUATION WHAT SHOULD BE THE VOLTAGE ON THE LOCK AND UNLOCK WIRES." - when in the locked or unlocked state the lock and unlock wires will measure no voltage at all - the way the ECU works is that a 0v pulse (a small interval short to earth/0v) occurs on either the locked or unlocked wire. That pulse tells the ECU to lock or unlock the doors according to which wire the pulse was sensed on.

"DOES TURNING THE IGNITION ON MAKE ANY DIFFERENCE TO THE VOLTAGES." No it doesn't make any difference at all - the ECU works the same for lock/unlock operations whether ignition is on or off - a pulse on the respective wire.

A 0v pulse on the mostly brown wire with a red stripe (BRRT in Haynes diagram) will cause the ECU to trigger the lock operation and a 0v pulse on the mostly brown wire with a white (BRWS) will cause the ECU to trigger the unlock operation. To test them, put your multimeter on continuity mode (where you can test if a piece of wire is "ok" for example, often the multimeter beeps to indicate continuity), put one probe on a known 0v/earth and the other probe on the respective wire and then lock. This should result in (using lock as an example) if you hold one probe on a known 0v/earth, and the other on the brown/red wire when you lock the car (use the button on the drivers door card) you should get a short beep (continuity). Then switching that probe to the BRWS and unlocking the car (use the button again) you should get another short beep (continuity).

Both wires can be found in the loom that is plugged into the ECU - you may need to unplug the connector to be able to correctly locate them.

Is that a bit clearer?

Hiya Daz, thanks - you can find the indicator wiring in the car without going to the engine bay though not at the locking ECU (I don't believe). Wire colours you're looking for are mostly black with a white stripe (L) and mostly black with a green stripe (R) - should be relatively easy to locate from the shroud around the steering wheel and the loom running down from there.

Remote Central Locking conversion.

Mostly brown with a black stripe - I think you should find it at the Central Locking ECU. Jumper it to mostly brown with red stripe and you should get closure on locking.

Another delay

Hi Andrew

Its Pinner-man. I am afraid, I have not got any further with my upgrade. Almost as soon as I got back from holiday I got a chest infection and spent a couple of days in hospital being pumped full of antibiotics, I am recovering quite well but it may be a few days before I can get back to working on the car. I will say that suggesting I check the colour coding of the connector to the remote receiver was good point. They use BLACK as the 0v or earth not BROWN.
