Cruise Control System Vehicle Speed Too High
The cruise control sees actual vehicle speed exceed the set-speed by more than the diagnostic margin (typically going downhill or with throttle override). Persistent oversize means the system cannot bring speed down - either an actuator fault, brake-blending failure, or driver kick-down stuck.
