Renault SM5 Cruise Control Failure

My 2019 Renault SM5 gasoline's cruise control is kaput! It just stopped working. The dashboard doesn't light up when I try to engage it, and I got a diagnostic error stored in the error memory. I'm thinking it could be a dodgy connection. Any ideas?

I had something similar happen on my SM5. Check the pedal switch and also the clock spring connection, it may be a connection problem with a plug. If the brake light switch is faulty, it can also knock out the cruise control. Speed sensor cable may also be defective. Did you check those?

Thanks! Where exactly is the clock spring connection located? Is it an easy DIY fix, or am I better off taking it to a workshop?

It's behind the steering wheel. Honestly, messing with the steering and airbag system can be risky if you're not 100% confident. I'd recommend getting it checked out at a workshop to be on the safe side. I had to pay 95€ for the repair.

Thanks a lot for the advice! I took it to a workshop and it turned out to be a defective cable, just like you suggested. They fixed it for around that price. I appreciate the help!
