I sure could use one if anyone has an All Data account or the like.
The ecm is not retaining the test's it's ran and completed. Something is clearing the date from the retained memory every time you shut the truck off.
I just want to be sure the ecm wiring that should stay batt hot at key off is doing so, before throwing a ecm at it.
