Very interesting point: a rapidly disconnect will send a voltage spike. The exact principle that generates the ignition spark. I would not be surprised if a broken bond wire closes and opens like the points of an old timey ignition coil and generates a high voltage pulse that kills something in the circuit.

If there is anyone who can take apart a module and take great pics, explain what failed its Andrew. Waiting on USPS... was supposed to be there the 24th delayed because holiday.

I grabbed a module from junkyard with same numbers and it gave me same exact codes (no programming necessary) and everything else works fine so can drive with same symptoms.

So either two modules both failed the same way or we will figure something out once he plugs it into either of his vehicles that have working DSC and no trifecta (again all modules have same numbers so no programming needed).
