P0565
Cruise Control On Signal
Cruise / speed control
Generic OBD-II
Low
What it means
P0565 means the module cannot properly read the signal that tells it the cruise control has been switched on. As a result the cruise control may not activate or may behave erratically. It is a convenience-system fault only — it does not affect how the engine runs, stops, or shifts.
Low
Can I keep driving? Fully drivable — only the cruise control is affected. Engine, brakes, and transmission are unaffected.

How to diagnose & fix
Work through it in order
- Scan live data to see whether the module registers the 'on' signal when you press the switch.
- Test the cruise on/off switch for correct operation.
- Inspect the switch wiring, connectors, and fuse for damage or corrosion.
- Check the clock spring if the switches are on the steering wheel.
- Replace the switch or module if the signal never reaches the ECM. Clear and re-test.
