Fiat Fullback ABS Traction Problems

Hi, I'm experiencing an issue with my 2020 Fiat Fullback diesel. The ABS lamp keeps lighting up, and I'm getting traction problems. It seems to be affecting the ABS system. I suspect a speed signal fault, possibly a defective control unit. The odometer reads 233041 km. Any thoughts before I take it to a mechanic? I'm guessing it has something to do with the ECM input or a faulty sensor.

Sounds familiar! I had similar ABS and traction issues with my Fullback. Was the speedometer acting up as well?

Thanks for the quick reply! Speedometer seems fine. So, you reckon it was a speed signal fault too? Did you have to replace the whole control unit?

Yep, speed signal was the culprit. I messed with it myself for a while, but eventually had to bite the bullet and get it sorted at a workshop. Honestly, save yourself the headache and get it checked professionally. It's likely the control unit needing replacement or reprogramming.

Appreciate the advice. I'll get it booked in. Workshop confirmed it's a defective control unit and quoted 1000€ for the repair. Thanks again!
