Fusion: Door Ajar & Tire Pressure Monitor Fault

[nwarren]

Hello,
Looking for help and feedback. My Ford Fusion is erroring out on me, on a fairly regular basis. The error typically only comes as I am 30 to 45 minutes into my commute (60MPH or higher). It starts by my dash lighting up with the brake light and other lights. Then the car reads “Door Ajar” followed by “Tire Pressure Monitor Fault” after which the gauges and the dash go black, the gages go down to zero, and then it comes back on. Sometimes the error will go right away again, and other times it will not.
Any help is appreciated! Thank you!

Usually something wrong with the charging system (bad battery or bad alternator) will cause the computer to receive voltage that is too low and it will start giving off all kinds of weird codes. I'd take it to an auto parts store and ask them to do a check to see if one of those two comes back as bad.
