Which brand of scanner was used in attempt to communicate with Powertrain Control Module (so tagged because it supervises engine and transmission\transfer case\front differential)?
Engine Control Module controls engine, only, as in a gasser (patooie!) - 6.5 with NV4500 is still PCM, with inputs from t\c and front diff.
Simple COBRA code-reader from Harborfreightdotcom will read\clear DTC's - Autozone can usually read them
