I have a Ford truck and my BCM has no communication.
We suggest checking the red harness plug that mounts the GEM module to the fuse box since that GEM module mounts directly on top of the fuse box. There could be an issue with the fuse box itself which we can rebuild. If the pins are dirty or corroded that could be an issue as well. There's also 3 grey plugs that connect the GEM module to the harness from the side.
