    LBZ GPCM Issues

    I cannot get any communication with my GPCM. swapped out both the module and the ecm and still no communication. im thinking its most likely the ground at this point. has anyone dealt with this issue before? looking for some help here with the cold temps setting in here this past week. thanks
