    I have this weird issue on my 2014 MX-13. She will throw a code for SPN-5112 Controller #6 and SPN-153848. The Seek Service will stay on for a few days then go away. However a few days later it returns again. We have been playing this game for the last two months, but the truck has been running great. Last week my mileage, trip and temperature displays disappeared (all else normal) in the afternoon but were back in the morning. A few days ago my door chime decided to stay on for a few hours for no reason (doors were shut), then it went away as well. Has anyone experienced these or similar issues? Could they be related and caused by an electrical issue? Any help is appreciated.

    My 2015 Pete Glider will occasionally loose the odometer, temp and hour gauge. Usually comes back on the next time I stop and start the motor. One time it didn’t come back on until the next day. Supposedly it is a Paccar problem as KW’s do the same thing. Mine doesn’t do it often enough to spend any money on it yet. I was told it was a computer issue, but I am not sure exactly which computer and whether it is worth spending the money on. I assume that your rig is an old USAL rig. In my opinion they are the Best Buy in the used carhauler market as they are very well spec’ed for company rigs. I know several people who have operated them and a few more who have bought them and they seem to be happy with them.

    Thanks for the reply. Yes it is a USAL truck and you are correct they are very well maintained. As matter fact this is my third set of wheels that came from them.
