UFO Instrument Cluster Error Message

coachmanrvr · 08-28-2010, 04:56 PM

Anyone with a UFO know how to acknowledge an error message on the instrument cluster? Mine keeps telling me that my left hand tail light is out and keeps the message up forever. (I replaced the bulbs and the message remains) This is the result of water getting into the tail light at a Blue Beacon truck wash.

Any suggestions?

See if you can take it a bit further back. There must be a modular plug behind the light fixture. Understand the bulb working OK and you are still getting the DTC message?

Yes, I have had the assembly off of the RV. There is a single three bulb assy that is attached to the light fixture. I am guessing that something in that assy is not 100 percent and is causing the error message. Everything works, just the message remains. I don't mind acking the message each time, I just don't want to replace the fixture to clear the message.

As I see it the rear computer (WISE) is not seeing the load (filament) at the other end of the wire. Apparently the computer thinks the circuit is open. It takes 2 things to make a circuit. Juice (12 volts) and Groumd. I expect that there may be something a miss with the ground if the light is working.
