Lexus CT200h ABS Fault

Hey, I'm having a weird issue with my 2022 Lexus CT200h hybrid. It's got about 109279 km on it. The ABS lamp lights up sometimes, and I'm getting traction problems; the ABS seems to fail at times. I'm starting to get worried. Could it be a speed sensor? I checked the fuses, and they seem okay, but I'm not sure what to do next. I was thinking of checking the ECM input, but I don't even know where to start. Any help?

A 2022 Lexus CT200h is experiencing intermittent ABS lamp illumination and traction issues, possibly due to a speed sensor fault. The fuses were checked and found to be fine, but the problem persisted. Error codes indicated a speed signal fault, leading to the diagnosis of a defective control unit. The issue was resolved by replacing the control unit at a repair shop.

I had similar symptoms on my 2018 Volvo V60. The speedometer was all over the place, and the ABS was acting up. Did you happen to get any error codes?

Thanks! Yes, I got some error codes. It points to a speed signal fault. Did your Volvo show the same error?

Yep, the error code suggested a defective control unit. Unfortunately, that meant a trip to the shop. I'd advise you to do the same.

Thanks, I appreciate the advice! I took it to the shop, and they confirmed it was indeed a defective control unit. The repair, including parts and labor, was around 1000€. It’s working fine now!
