Hmmm. I like that idea as an extra troubleshooting step. I do have data logging capability as well as chip burning. I will try the idea you suggested though. Seems worth a shot just to prove I am getting what I expect. I'll probably try both open and closed to trigger each error.

On a positive note, I guess, I just finished testing the wires. I could not detect any issues in either the CTS or ICM wires. Wiggled like crazy everywhere I could and no change in continuity. Ordered a new CTS. ICM should be here Thursday. Ordered both the D1943A and the Police version D1984A. The D1943A will go in my onboard spares bin.
