10 Steps on How to Clear Service 4WD Light
Step 1: Identify the Issue
The first thing you need to do when trying to clear your 4WD service light is to identify the underlying problem. This can be done using an OBD-II scanner or taking your vehicle to a mechanic for a diagnostic test. Once you have the trouble code, you can determine the cause of the issue and how to resolve it.
Step 2: Check for Loose Connections
One common culprit for a 4WD service light is a loose connection. Check all electrical connections to your four-wheel drive system and ensure they are securely connected. If any links are loose or damaged, repair or replace them as needed.
Step 3: Inspect the Transfer Case
The transfer case is critical to your vehicle’s four-wheel drive system. It can trigger the 4WD service light if it becomes damaged or malfunctioning. Inspect the transfer case for any signs of damage or leaks and make necessary repairs.

Once you have identified and resolved the underlying issue, it’s time to reset the 4WD service light. This can be done using an OBD-II scanner or disconnecting the battery for a few minutes. Be sure to consult your owner’s manual for the correct method for resetting the light on your specific vehicle.
Step 8: Test Drive
After resetting the 4WD service light, take your vehicle for a test drive to ensure the issue has been resolved. If the light stays off and your four-wheel drive system functions correctly, you have successfully cleared the code.
Step 9: Address Any Other Issues
Sometimes, multiple issues need to be addressed to clear the 4WD service light. If you have followed all the steps and the light is still on, it’s best to take your vehicle to a mechanic for a thorough inspection and diagnosis.
