P0649 OBD-II: Speed Control Lamp Control Circuit
P0649 Severity
Moderate
Will P0649 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 P0649?
The Cruise Control Warning light should illuminated for a few seconds when the key is initially turned on. If the warning light fails to light, the engine control module (PCM) will set code P0649.
