BCM Beeping?

Postby smudge801 » Wed Jan 09, 2019 7:52 am

I've had electrical issues, beginning with replacing the blower fan relay. When doing so, I also checked the accessory relay next to it and found a bit of melting in the socket. Purchased a replacement fuse block and more new relays. Put them in, replaced all the harnesses and remounted the fuse block on the BCM. Now the car cranks, but no ignition. It was fine when I tested all before remounting. Something changed when I put it all back.There is beeping occasionally when I move the assembly a bit. Seems like the BCM beeps. Anyone know what that is and why? All fuses are intact and the relays are new. I don't see what might be interrupting firing.

Was your vehicle ever in a flood?

Read the EC chapter in the FSM for your vehicle

Never flooded. Been in the family in TX for 15 years. Will read up on the EC chapter. Thanks.
