I've been fighting to get the creep function to work. It's driving me crazy. I'm using a ESR10 Micro solid state relay, and I've gt the creep button grounding to E12 (as per my other post). I've got it hooked to PA Hold and it's switching on the XFI as I can see PA Hold changing from 0 to 1. But obviously something is wrong because I've tried all different settings and nothing seems to work. I suppose the 1st question is after making changes in the Trans Brake Parameter screen can I just press apply and try? After that what other ideas can I explore or test?
