I'n trying to solve an electrical problem on a M935 for somebody. So far I have no parking brake light, switch tests good I think, It shows open whith p brake applied and closed with parking brake released, No power to parking brake switch, No power to either low pressure switch either. Just wondering if anoy one else had run into this and if so was it the fail safe module? What I am getting so far and what I am reading in the TM's make me think it's the fail safe.
