Hmm. Looking at the wiring diagram for the PRNDL circuit, the BCM is nowhere to be seen. Based on reading forums for many years the usual culprits are the TCM or the TRS switch assembly in the transmission. Hope they know something we don't know.

Uh Oh. That's for a Caravan not a Concord.

 

Ok, smog is coming up, and I had to fix it! Ordered a used TCM form Ebay....installed it today, and the PRNDL indicator is working, check-engine light is off!! I didn't believe it, put the old one back in, same problem...so it was the TCM, woohoo!

 

Nice to read someone has 'bottomed' this kind of fault.
