Fault code U0401?
Posted: Sat Jan 12, 2019 1:36 pm
2 days in a row now my Ranger has thrown U0401 error code (see pic below).
Started my car first thing in the morning yesterday, it idled for about 1min then drove out my street as I do every morning. Lots of short curvy streets around here so I just take it easy so 1500-2000rpm max and 3rd gear tops (auto trans). Got less than 500m from my place and the change into 3rd was more like a small thump, then 5 secs later the stability control light came on and stayed on (no other lights). It then seemed to lock into 2nd/3rd gear but otherwise drove fine. Went back home to get my Forscan bits, got the code in the picture below. Restarted the car and the light went off and drove perfectly for the rest of the day, no more dash lights.
Exact identical issue this morning, again I turned it off the restarted and was all good, did about 50km with no issues.
Gearbox was flushed about 10,000km ago and no issues until yesterday. Tranny guy does work for the local Ford dealer so he knows these in and out and hopefully used the right fluid.
The code mentions ABS (dirty sensor?) but why would the tranny thump into 3rd then go into limp mode?
Any ideas??
The other BCM fault is just the sports bar light missing
