جدا بودن کابل سروو

The cable between a cruise control servo and the throttle, disconnected or broken. On a cable-operated system the servo pulls the throttle mechanically, so this link is the whole of its authority.

Cruise control engages and nothing happens — speed is not held, and the module reports that its command produced no response. The servo, the switches and the module are all fine, which is what sends the diagnosis to the electronics. Look at the linkage first: these cables have a ball-and-socket or clip end at the throttle that pops off, and the failure is visible in seconds with the bonnet open. Check the cable's routing and adjustment while there, since one that is slack cannot take up before the throttle moves.
