Fiesta ABS Lateral Acceleration Sensor Fault

Help! My 2014 Ford Fiesta diesel has a weird ABS problem. The ABS light is on, and the whole system seems dead. A diagnostic scan shows a lateral acceleration sensor fault. Could a defective control unit really cause this?

I had a similar issue with my Fiesta. The lateral acceleration sensor can definitely cause those symptoms. Have you noticed any other strange behavior with the electronic stability control?

No, just the ABS light and the system failure. The error memory also stores the fault. What was the final fix for your car?

Sounds very similar to what I experienced. In my case, the control unit was indeed defective. I ended up having to replace it at the workshop. I'd suggest taking it in for a proper diagnosis, it might save you some headache. The repair ended up costing me around 1000€.

Thanks for the info! That confirms my suspicions. I'll take it to a workshop. Sounds like I am looking at a similar repair cost. Appreciate the help!
