2001 citroen xsara picasso wiring diagram

We have this problem too - can only lock the doors by shutting front doors - climb into the car via the back doors - lock front doors from inside and then manually lock back door. Boot is difficult to lock - takes about 3 or 4 attempts to lock it. Driving me mad!! Have been told it is probably worn or broken wires in the flexi hose in the door hinge. I may have to take it to the garage to get repaired.

I see several different problems here.

First, installing aftermarket accessories like remote starts and alarm systems is asking for electrical problems with your vehicle. Those things are known to cause all kinds of problems including stalling, incorrect air/fuel ratio, and no-starts. Not to mention that the vehicle wiring harnesses usually get BUTCHERED in the process of installing them. They also make diagnosis of future problems (like stalling, no-starts, or computer fault codes) nearly impossible because the repair technician has no way of knowing if the aftermarket accessories are at fault or if it is being caused by a malfunction in the factory equipment.

Then, if you do not know where to start, it makes me question whether you should be messing with the electrical (and most likely, computer) circuits in your vehicle to begin with.

In addition to that, there is no way that anyone can help you to perform that task without having the instructions from the manufacturer of the system you are trying to install. Different systems tie in to different circuits in the vehicle. There is no way of knowing which vehicle circuits you are needing diagrams for. Did the system not come with instructions?

I have 2 recommendations for you:

1. Don't do it. If your vehicle is not equipped by the manufacturer with the options that you want, you are better off to save your money to buy a car that is.

2. If you choose to ignore recommendation number 1, I recommend that you seek the assistance of a qualified automotive repair technician in your area.
