P0564

Cruise Control Multi-Function Input A Circuit

Vehicle speed & idle control Generic OBD-II Low

What it means

P0564 means the module saw an out-of-range signal on the "A" input of the cruise control multi-function switch — the buttons you press to set, resume, or cancel cruise. It's a comfort-feature fault: cruise control may not work, but the engine and drivability are unaffected. The usual cause is the switch itself or its wiring.

Can I keep driving? Safe to drive — only the cruise control is affected; the engine runs and drives normally.

How to diagnose & fix

Work through it in order

Read freeze-frame, then test the cruise control switch inputs for the expected voltage steps at each button.
Inspect the switch wiring and connectors, including the steering-wheel clockspring, for opens or shorts.
Replace the multi-function switch if its resistance/voltage steps are out of spec.
If the switch and wiring are good, suspect the control module. Clear and re-test.

FAQ

Quick answers

Is it safe to drive with P0564?+

Yes. Only the cruise control is affected — the engine and brakes work normally. You just won't be able to rely on cruise until it's fixed.

Can I just clear P0564?+

You can, but it returns the next time the module reads the faulty switch input. Repair the switch or wiring first.
