DO NOT BUY bcm's online...especially if they're used. Reason being is they have to be programmed to your vehicle. For example...if you have certain options (keyless entry, power sliding doors, etc..) and the bcm u buy isn't "set up" for it...they won't work. A bcm, like any other electronic component is yours the moment u buy it. NO RETURNS!! Also, if you have a factory alarm, or a programmed key for your vehicle..the wrong bcm will NOT allow these options to work. It's just like buying a used computer for your engine...you MUST program a VIN# into it, key codes, etc.. into it or it WON'T work. Becareful how you spend $$ on online modules. Remember....NO RETURNS!! You buy it...you own it. Good luck. P.S...the electrical issues probably have nothing to do with your engine repairs UNLESS someone pinched a wire during the head replacement.

The truck will not start if the BCM is repalced but not programmed. The theft system will prevent it for several reasons.

you need the unlock code from the manufacturer. I had a radio lock up but the company had me send it to them for them to unlock. i had to prove that i bought it and it was not stolen.

reprograming is very common, this is done all the time even with newer cars, some times cars new newer or diffrent programing installed in them and dealer is the only one that can do it unless someone has a dealer scan tool.As far as replacing it would depend on the problem and i think the dealer would of told them the computer was bad. hope this helps.

thats a issue for a pro cause dealers dont have olschoolers with the knowledge-they just want to sell new cars--independent shops must reprogram the computer using a landline only cause a wireless connect doesnt download the complete data--send delemma to [email protected] for more advice
