P0568
Cruise Control Set Signal
Cruise control
Generic OBD-II
Low
What it means
P0568 means the ECM saw a problem with the cruise control 'set' signal — the input used when you set a cruising speed. It usually points to the cruise switch or its wiring rather than the engine itself. Cruise control may not engage, but the vehicle is otherwise unaffected and safe to drive.
Low
Can I keep driving? Safe to drive — only the cruise control is affected; all normal engine and braking functions are unchanged.

- Inspect the switch wiring and connectors for shorts, opens, or corrosion.
- Repair or replace the switch or wiring as needed, then clear and re-test.
- Only consider the ECM after the switch and wiring check out.
FAQ
Quick answers
Is it safe to drive with P0568?+
Yes. Only the cruise control is affected — the engine, brakes, and steering all work normally. You just won't be able to use cruise until it's fixed.

You can, but it will return whenever the faulty switch or wiring signal is seen again. Fix the switch circuit to clear it for good.
