Hello, I have a problem with an old e38. Namely, the central locking on both front doors does not work. I started checking it for the Pbus line. A blue-red wire comes out of the GM connector on pin 25, I think. It is supposed to control the PM modules in the doors, among other things, about opening and closing. I checked it and it is not broken anywhere. I will add that from the set of switches on the left from the driver, only the driver's window and mirror work. I also replaced this switch, which is itself a PM module. I also replaced the PM module in the passenger door, but without success. The previous owner also replaced GM3. Maybe someone had a similar problem? thanks

Silly question, but is the power supply is there with the PM modules?

If you read the GM, can it be communicate booth PM module?

Limited information you should receive thereafter 
I sense from far away.
