P0566 OBD-II: Cruise Control "Off" Signal
P0566 Severity
Will P0566 go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P0566?
The Cruise Control System is controlled by the Body Control Module. The Body Control Module monitors driver inputs to the cruise control system and sends that request to the engine computer (PCM). If the body control module detects an invalid input from the cruise control "Off" Switch, code P056 will be set.
