How to Reset the Service Light on a Jeep

Instructions

Things You’ll Need
Wrench
Ignition key
OBDl or ll scanner

1. Disconnect your battery cables from the battery posts with a 6-pt. closed wrench in the size appropriate for the battery bolts. Remove the negative (black) cable first. Leave the battery disconnected for several minutes, according to Allpar.com. Reconnect, this time starting with the positive cable, and crank the engine. The code should be gone.

2. Crank the Jeep. Drive it forward, then backwards, and shut off. Repeat this procedure three times. The codes should clear on the fourth crank.

3. Use a OBDl or OBDll scan tool. Plug the tool into your Jeep’s ALDL (Assembly Line Diagnostic Link), a small, rectangular electrical port usually located under the dash. Turn the key to the “on” position. Scan the computer for codes and select the option to clear the codes.

4. Wait for the code to clear itself automatically. Once the component is fixed, the check engine light disappears after several successful ignitions. The code is then stored for a while. If the engine continues to start and run without a re-occurrence of the original problem, the code is wiped out.

How to reset the service light on your Chevy Cavalier

1. Make sure the light is has a wrench icon. This article is not intended to help reset a “service engine” light.

2. Without turning on your car, turn the key to the right and you’ll see all of your dash lights come on.

3. Press on the brake 4 times. On the 4th time, hold the brake petal down for 30 seconds and release. This should reset the light.

4. Always always always contact your mechanic! This trick was told to me by my mechanic because I saw the light and took it in for servicing. I went to a non-dealer mechanic, but after they ran a diagnostic, they couldn’t find anything wrong. I called my GM mechanic and they suggested that if noting was found wrong, it was probably a light that needed to be reset. I plan to take it in for a tune-up soon but knowing that nothing serious was wrong was a nice weight off my shoulders and my wallet!
