BCM Malfunction

[David Acosta]

Theft deterrant light comes on, airbag light comes on, and speed odometer going crazy. All of my gauges basically go crazy on my cluster after 2 minutes of driving. I want to say its the body control module but I also think its the HMI. I need help with this issue. Do i order a new BCM and have it snet in to get programmed to my VIN or take it to the dealer and

I would lean toward BCM. I think HMI only pertains to your touchscreen and the small screen within your dash cluster.

Before you drop money on a BCM, have you has the “bad ground” fix done yet?  By that, I mean the ground that is up near the driver side A pillar isn’t a good ground.  It needs to have insulation removed from around it and tightened down.

U can probably take the hmi out and run the jumper wires two blue and two white from the connector just to rule out the hmi going bad, but might be that ground like they said I haven’t messed with that but doesn’t sound hard from what others have said
