I read page after page of diagnostic information, which seemed to all start with, “Remove and check connections for powers and grounds.” Yet, after reading the same info time and time again like it was Groundhog Day, I finally found this paragraph in the diagnostic tree: “If none of the buttons work, disconnect the battery for five minutes, then reattach the battery connections and restart the vehicle. This way I could play a little hide and seek to see where this game might lead. Nothing in the car was talking to anything else, but I knew the airbag had some information it was not telling! Seeing how I had never run across this problem before, my thoughts were to read every line, every link and every note on the two other “U” codes in the diagnostic and description pages. It was effectively tattle-telling on one of the other modules.īoth the radio and the A/C had “U” codes stored for loss of communication.

This is only to report that the Restraints Control Module (RCM) received a missing or invalid message from another module.” What the code was telling me was that the airbag was fine. I looked up the definition of the code, “U0422: invalid serial data,” but its description left me even more puzzled. I thought that I might as well start somewhere, and the airbag seemed as good a place as any. (Real nice when it’s 95 degrees in the shop already, but it is what it is.)ĭoing a full scan on the car led to three codes popping up - one for the airbag, one for the radio and one for the HVAC system. The A/C was stuck on MAX hot air with the blower on high speed. Not a single button on the touchscreen did anything at all although, you could change the volume and select limited stations from the steering wheel controls. I’ve run across a few common causes: changing a battery, loose battery clamps, jumpstarting another car, etc.Īn example of one of these breakdowns rolled into my shop in the form of a 2013 Ford with no radio, no A/C and with the airbag light on.

How that corrupted information gets in there is still a mystery to me. This communication breakdown is usually caused by some corrupted information being passed from one module to the next. These days, with the advent of multiple computer systems crammed under the dash and hood, it was just a matter of time before communication between the modules was going to be an issue.
