P2771 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.
The Four Wheel Drive Switch allows the driver to shift from 2-wheel drive to 4-wheel Low or 4-wheel high, depending on driving conditions. If the transfer case does not engage in four wheel low, code P2771 will be set.
