Thalia Cruise Control Failure

Hi, I have a 2014 Renault Thalia with a gasoline engine and about 222083 km on the clock. My cruise control has stopped working recently. It doesn't engage at all and I get an error stored when I check it. I've checked the dashboard lights and the fuse. I used to have an issue with my brake light switch on my old Megane causing similar problems, but the brake lights on the Thalia seem okay. Any ideas?

The cruise control system relies on several inputs to function correctly. Is it possible a defective cable or plug connection is responsible? Have you considered other potential causes such as the throttle position sensor or the steering wheel controls? It's important to investigate these before proceeding.

Thanks for the quick reply! I haven't checked the throttle position sensor or the steering wheel controls specifically. How would I test those, and could a faulty connection there really kill the whole cruise control system?

Yes. A faulty connection or sensor within the cruise control circuit can disable the entire system as a safety measure. Given the complexity and your technical experience, it might be prudent to consult a qualified mechanic with diagnostic tools to pinpoint the exact source of the error. It could prevent unnecessary expenses due to misguided repairs.

Thanks for the advice, I appreciate it. I booked it in and the mechanic confirmed it was indeed a defective cable connection. Repair cost was 95€. Sorted!
