    Do TPMS need to be reset when rotating tires?

    But if the older cars like my 2004 dont show psi per wheel or tell you which wheel is low, why would you need to program via DIC?

    Do TPMS need to be reset when rotating tires?

    My truck is a 2004, but my friends is a 2013. On my truck I think there is only a light, unless it says on the screen which tire is low. I dont think my 2004 can tell me the PSI and which tire is low, I think just a general low pressure light will come on.

    Electrical Issue 2004 Tahoe Z71

    well bad news, the BCM didnt fix the problem after all. After working great for over a week today the car started slowly like the battery was low and the guages stopped working again. I let the car charge the battery, then started it again at 12.5v but it didnt help. I also started the truck...

    Electrical Issue 2004 Tahoe Z71

    Based on all these random issues I am starting to think the body control module is faulty however I just found out you have to have a damn dealer program the new one? That really sucks.
