Hey guys

i've been having problems the past couple months with my indicater lights going on and the car running like ****

they've scanned it and haven't really found anything specific yet BUT can a scanner tell of the BCM (body control module) is bad?

thanks

 

I dont think the hand held ones you buy at AutZone can tell, but I think a GM Tech II can tell.

 

If it's bad you usually get communication trouble codes appear in obd II.
