Where are the BCM connector pins and numbering system?
BCM Connector pins and numbering system. Finally I’m trying to run a wire from my tailgate conversion to the BMC. I’ve run the wire, removed the BCM and opened the black connector. What I can’t see is where pin 23 is in the connector.
How is the BCM connected to the headlight switch?
The headlight relay is switched by the BCM, which in turn is commanded by the headlight switch. In this case, the headlight switch acts as an input to the BCM. In most cases the wiring to the headlight switch is just a single small gauge wire. The BCM supplies low voltage to the headlight switch on this single wire and monitors the voltage.
Where does power go in a BCM Body Control Module?
The power then flowed to the headlight switch, and from the headlight switch to each headlight. The wire used for the run from the fuse to the switch and from the switch to the headlights had to be a large enough gauge to handle the current load of the headlights.
Where does the BCM go to unlock the tailgate?
I’ve run 2 wires from the BCM to the lock, one goes direct to the lock motor and one goes to the switches. Earthing the switch wire should trigger the BCM to unlock the tailgate. But it isn’t I’ve connected VCDS and in Module 9, I’ve enabled what I can see for the tailgate.

Can A B + circuit cause an open BCM?
An open or short in any one of the \+ circuits may induce multiple codes/or a section of non-functionality within the BCM with the rest of the BCM functioning normally. In this case it is useful to refer to the power distribution schematics to determine if the non-functional partition of the controller shares a common B+ circuit.
What are the BCM numbers on a Raspberry Pi?
Unfortunately the BCM numbers changed between versions of the Pi1 Model B, and you’ll need to work out which one you have guide here. So it may be safer to use the BOARD numbers if you are going to use more than one Raspberry Pi in a project. The Model B+ uses the same numbering as the Model B r2.0, and adds new pins (board numbers 27-40).
