BCM limp mode

try disconnecting the battery for about 20 minutes and see if that does anything for you.

JohnnyT73 do I need to reprogram the BCM after replacing the airbags

to my knowledge you do not.

you may need to erase the codes in the BCM. If it continues to set codes then there is still fault.

Thank you for helping a fellow technician (student technician) out

That would mean a wiring issue most likely a short correct?

Thats usually how airbag circuits work. They function by causing shorts in the system. If you can pull the codes it should guide you in the right direction. If the airbags deployed and you replaced the airbags then if the car has pretensioners in the seatbelt(s). They pay have discharged as well and need replacing. Check codes first though.

Stupid question...I haven't been a tech for long...how would you check the pretensioner to see if it had deployed

It's kinda hard to describe so that it makes sense. You will have to visually see it in the car. The part that the seat belt connects to is usually about a 5-6 inch cable coming out of the pretensioner body. If it looks like it's pulled into the body then it has discharged. The codes will tell you if the pretensioner is short circuited.

I got a 2004 Buick rendezvous it stopped on me wouldn't jump off when I got it home changed starter didn't help but left it unhooked from battery now found inside car 30 amp metal fuse bad do I need to reset bcm cause I now don't have low beam head lights window want work doors locks don't work so what cause that

It sounds like the BCM has had a problem could be from a voltage spike when the battery was connected.

You will need the BCM reprogrammed by a shop here is the location.

Please let us know what happens.
