P0636 Severity
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.
Despite the code definition provided, most manufactures use this code to identify improper charging system operation. If the engine computer (PCM) detects the Alternator is not providing sufficient output to run the electrical systems on the vehicle and recharge the battery, code P0636 will set.Any non-essential electronics will also be disabled (i.e. Radio, Climate Control)
