Twizy ABS Speed Signal Fault

I'm having a speed signal fault with my 2023 Renault Twizy (electric). The odometer reads 217417 km, and now the ABS lamp is constantly lit. I'm also experiencing traction control issues, which I suspect is linked to the failing ABS. I've checked the transmission, the speedometer, and the sensors, but nothing seems obviously broken. I'm starting to think the control unit itself is defective. Has anyone else run into this with their Twizy?

A 2023 Renault Twizy is experiencing a speed signal fault, with the ABS lamp constantly lit and traction control issues. Despite checking the transmission, speedometer, and sensors, the problem persists, leading to the suspicion that the control unit might be defective. After taking the vehicle to a workshop, it was confirmed that the control unit was indeed faulty and needed replacement, resolving the issue.

Did this summary help you solve your problem?

ABS light and traction problems? Sounds rough! Did you check the sensor connections themselves? Sometimes it's just a loose wire or corrosion causing the issue. Also, is the speedometer working correctly, or is that acting up too?

Yeah, I checked the sensor connections; they seem solid. The speedometer is intermittently going haywire, which further points to the speed signal being the core problem, I reckon. Since you mentioned the speedometer, is there a specific sensor or wiring harness you'd recommend inspecting more closely?

Speedo issues definitely point to a deeper problem then. Given all those symptoms cropping up together, and especially with the speedometer acting up too, it really does sound like that control unit. Honestly, at this point, a workshop might be your best bet; ABS issues can be tricky and risky to DIY.

You called it! Took it to the shop. Turns out the control unit was indeed fried. Cost me 1000€ to replace, but at least it's finally fixed. Thanks for confirming my suspicions and pointing me in the right direction!
