1994 Dodge Ram V8 Two Wheel Drive Automatic 150000 miles
Got an error code of 12 "Problem with the battery connection. Direct battery input to PCM disconnected within last 50 ignition key-on cycles" Occasionally the truck would just not fire, like it was getting no fuel, this last time I was showing no fire from the coil so I replaced that along with the cap and rotor. I checked voltage at the coil wire harness, and got 13 volts when set to a body ground, but only got 5 volts when grounded to the harness. How do I check the battery connection to the PCM, or anything else I might need to check?
have the same problem?
