Does anybody out there have a connector pin-out and possibly a sequence of operations (truth table) for the Electronic Shift Control Module for a first gen?
I am trying to trace some intermittent problems that look like they are related to wiring problems in the harness running along the driver side frame rail. Some idiot cut through the bundle and the wires just under the driver side door. No problem repairing the obviously cut wires, but he (?) also nicked the insulation on some others. I found this out the hard way when the rear anti-lock light would intermittently come on. After going through the rear end sensor, connector, etc., it came down to a wire that corroded into a round tube of crud inside the remaining insulation. Fourteen inches of wire, some shrink wrap and copoious quantities of verbal explorations later, the questionable system works again.
The latest manifestation came this morning - after digging out a totally buried vehicle - when the 4WD wouldn't engage. Transfer case motor fairly recently cleaned, so ruled out - at least temporarily. Checked the ESCM and LED not lit - reset and tried again - no relay click and
LED out again. The only wiring diagrams I have really suck! Basically they show that there is a module and that it has 12VDC going to it.
Comical musings in the NE bllizzard, wel at least to a southern boy who is stuck up here for another year.
Even with only 2WD, Explorers are going where others fear to tread.
The rust bucket is entering the geriatric years exhibited by things slowing down. For example the drivers side window which goes down at a rate directly related to temperature - the lower the mercury, the slower the window. In sympathy, the radio varies its volume in the same manner - lower=lower.
This is getting too long - look forward to some USABLE wiring info on the "black box".
NOTE TO MODERATOR: There are some wonderful information on the 4x4 probs available by search - however, there are so many redundant threads that it is getting very cumbersome to wade through them. Maybe time to delete some redundant postings???
