Lexus RX ABS Speed Signal Fault

That ABS issue sounds familiar. I had a similar experience with my old BMW 3 Series. ABS light, traction control going nuts – the whole shebang. In my case, it turned out to be a faulty ABS sensor. Did the diagnostic specifically mention the control unit, or could it possibly be related to one of the wheel speed sensors feeding incorrect data to the unit?

Thanks for the quick response! The diagnostic was pretty specific about the control unit being affected. It's throwing a code that suggests internal malfunction. I'm just trying to gauge how common this is before I commit to replacing the entire unit. Was your BMW diagnostic as clear as mine?

Ah, okay, a specific control unit code changes things. My BMW's diagnostic was more vague, pointing to a sensor issue, which is why I asked. If your diagnostic directly names the control unit, and you're seeing those ABS symptoms, it does sound like that's the culprit. Honestly, with potentially safety-critical systems like ABS, I wouldn't mess around too much. I'd bite the bullet and take it to a reputable workshop before things get worse. Good luck!

Appreciate the advice! Based on your experience and the diagnostic results, I decided to take it to the workshop. Turns out the control unit was indeed defective, as suspected. Repair cost me around 1000€. Thanks again for the help!
