Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

Wow very nice diagram and information too.

Sir, I could not locate the wires specific to lock and unlocking doors on the BCM module as per the diagram attached by you ie central locking and unlocking wires.

It would be pleased to hear if such particular wires on the BCM were located easily by providing the individual pins description of the input and output connector of BCM unit.

Once again thanks.

Yep, here is the the full BCM wiring diagrams for you. Let me know.

Indeed very much appreciated for your concerns.

But, I could not locate the particular wires for central door lock and unlocking.

There are many wires, door switch, driver door lock, etc., which really confused me. Wish you could kindly make some markings on the specific wires for central door lock and unlock so that I can identify easily and send new diagrams.

And, the wires codes and colors are not the same as against their respective pins numbers. And, how to count pin numbers?

(Actually, I try installing aftermarket remote car lock in the car which already comes with central locking system.

On the remote control unit, there are two wires for lock and unlock doors. And, I am sure connecting these two wires to their respective control wires on the input connector of BCM module.)

Sorry to trouble you again, yet hopeful to see another help once again. Thanks.

Hmm,
These are the wiring diagrams they give us because this car is EURO it might be a little different. The instructions for the alarm are difficult to read. Can you reload them please?

Sir, is the input signal following the given direction.

Input signals --- input plug connector on fuse panel under steering wheel --- input connector of BCM module --- output connector of BCM module ---- output plug connector on the said fuse panel --- output signal


And, sir, please find locate the wires for lock and unlocking all doors for central locking. Pictures attached herewith. I am really confused.

Thanks.

That is because there is no central lock command they are individual. This alarm might not work with your car.

Okay, let's forget about the alarm system.

Where can I locate the wires for lock and unlock signals?

The car already comes with factory fitted central locking system.

Those all come out of the BCM, check the wiring diagrams for more details.

Sir, here is the driver door lock actuator. Connector with four wires of the door latch of the driver's door.

The first two wires are of same thickness and last two are of bigger size in thickness.

Now, probing individually again.

With the door switch kept to close position telling the car that all doors are closed. ( At this point, all doors are kept locked)

1. Connect one end of sorting wire/test-light to ground and the other to the 1 pin of door actuator --- all doors unlocked from locked position.

2. Now, I disconnect the join test light, then --- all doors locked from unlocked position.

3. The last two wires does not give any outputs on joining individually to earth. And it seems they are not related to locking system.

Is it that the doors lock and unlock function are controlled through just only the 1 pin or wire connected to the actuator?

If so, how to connect the lock and unlock wires of the remote control unit to just the single 1 pin of the connector?
Thanks.

Hmm, must be different that the wiring diagrams. I rechecked the wiring and that is all they give us. Yours must be different since it is a Euro car. You are going to have to do a little trial and error.

Okay sir,

The rear defogger does not work.
I press the rear defogger button, no signal flow and eventually the rear defogging is not working.

Other functions like AC, front fogging etc are fine.

Please help me solve the issue.

Once again thanks.

Sir, happy to inform you that I locate the control wire on input connector of BCM module.

However, it seems the wire does not correspond to the same colour code and pin number as per the diagram provided by you.

Indeed very much appreciated your help.

Yep, the colors might be a little off because we have US car information. Good job on getting it going though. Use 2CarPros anytime, we are here to help. Please tell a friend.
