Lexus LFA Cruise Control Failure

I had a similar cruise control issue on my LFA some time ago. Do you notice any difference in engine behavior, or is it solely the cruise control that's affected? Did you already check the fuse box? It might be related to the actuator or the throttle body.

Engine performance seems unaffected, and it is indeed only the cruise control exhibiting the issue. I have yet to inspect the fuse box, but I will do so promptly. When you had this issue, do you recall the error message or code displayed?

The error message was similar, something about a faulty system. Checking the fuses is a good first step. In my case, the problem persisted even after that. I'd recommend getting it checked by a professional if the fuse isn't the cause. It could save you a lot of time diagnosing it yourself. Turned out for me that it was a defective cable.

I will begin by inspecting the fuse box. Should that prove unfruitful, I will proceed to have the vehicle assessed by a qualified technician. The repair ended up costing me 95€, because it was a defective plug. Thanks!
