well spent the day fitting a car alarm to the rover, central locking proved to be a bit of a challenge, ended up with 2 relays to provide a continous circuit and and a earth circuit on demand, this allows for the door to be unlocked normally, or for the alarm to lock and unlock as required, ended up using the headlights as a flasher as it appears the side lights run directly off the headlight switch, yet to fit bonnet/hood switch and a switch interface for the rear door.

Do you have a schematic to share for what you did?

 

i will sketch one up and upload it, my net is running really slow so not tonight

Asking for help with alarm-immobilizer. My Ex-td5 Disco2 2001, actually a D5 - with a OM617 5 liner MB engine - have little dependency on the ECU. I HAVE a problem with the alarm / immo. If anybody could help me REMOVE these items. I could provide 100% proof of ownership for my very old, battered and loved Discovery 2 Ex-TD5. Otherwise, I´ll be blindly removing ALL CPUs and rewiring. (Yeap, its going to be a nutty job).

Tks and Regards

The dealer or a high level shop computer might be able to unprogram it. The fuction is built into the ECU and BCU and forces them to communicate a code string message. It is not just unplug modules or snip a wire. You may not need the ECU, but the BDU needs to be there.

 

Thanks for answering. Really I don´t need ecu and or bcu. I don´t mind for alarm for such and old truck. AND nobody is going to steal a Discovery 2001, at least here, where I live (The Dominican Republic). So, theoretically, if I decided and remove cpus and convert all wiring so every window and/or velocimeter/rpms, signalization, lights, dash instruments to non cpu system??

Its not so difficult to do such thing, just lengthy and boresome.
AND as I said, the truck has a 5 cyl Mercedes TurboDiesel with a MB 4 speed auto trans, the original transference box, every mechanical thing in working conditions.

Tks

If you could copy me the schematic of what you did, I´ll thank you very much.

You could rewire truck. The BCU also signals the IDM module on the fuse panel for various things like locking. The BCU deals with wiper delay, turn signals, etc. Lots of things to re-invent.

Why not fix the alarm problems? The immobilization stops spark and fuel pump, easily bypassed.
