P0569: Cruise Control Coast Signal
What to do
Driveable. If cruise control engages and then gradually loses speed, this switch is a likely cause and worth mentioning rather than assuming a mechanical fault.
What this code means
A fault in the coast signal, which reduces the set speed while held. A stuck coast input causes the vehicle to bleed off speed while cruise control is engaged, which reads to a driver as cruise control that will not hold — and is easily mistaken for a servo or vacuum fault.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
