Bcm Programming

[pjaneiro]

I went to my local dealer today to have my pcm updated with the new cal files and at the same time i asked them if they could re-program my bcm, the tech told me (even without checking) that he can't as the bcm is only a one time programmable, is this true ? i remember clearly them re-programming my bcm for the fog lights and the keyless entry, now i want them to remove thr rpo code t61 and replace it with t62 so my drl are disabled, and they told me no, is there a way to do it or is he just pulling my chain and can't do it ?

 

if so, could those aftermarkets programmers do it ?

 

Thanks...

the bcm can be reprogrammed to update calibrations and so forth, but when you put a new bcm in you have to set all the option codes and set the accessories that it does and doesnt have, that part of it is a one time thing and is permanent... so no, there is no way to change the option codes once they are set..( unless you wanna replace your bcm?)

and no aftermarket would do that

I could be wrong but I don't believe that to be true. They can call tech line and get a code to add any option.
