Need help
Getting codes H31,H33,H35,H37 on module 1 for my 93 read into the codes which state its an LCD Data short from the battery or CCM. Checked the battery and its not that grant it the battery is only 2 months old and im getting the 12v I need so it must be the CCM, took that out looked at the connections and they are fine no corrosion not bent etc and looked jnside the the CCM and no signs of burning etc. I dont know what to do could it be a fise or could the starter have gone I replaced that last month. Really need advice I EAS this Thursday and if I can get it fix nice if not truck and trailer.
