How to Reset the Engine Warning Light on a Jeep Wrangler Sport
by Katebo
A Jeep Wrangler Sport comes with a Power Train Control Module (PCM) computer on board that diagnoses problems throughout the vehicle. When the engine warning light illuminates on the instrument panel, this is the result of a trouble code sent to the PCM. You can take the vehicle to an auto parts store to have it diagnosed for free, and then you should have the problem fixed by a mechanic. Once the problem has been rectified, you can quickly and easily reset the engine warning light.
Step 1
Open the hood and find the positive battery terminal. Loosen the bolt attached to the clamp with an adjustable wrench. Remove the clamp from the terminal and take care not to touch it to the negative side of the battery. Wait one minute.
Step 2
Replace the positive clamp to the positive battery terminal and tighten the bolt with the wrench.
Step 3
Put the key in the ignition and turn it to the "On" position for about five seconds. Turn the engine on. The engine warning light will flash and then turn off.
