How to Clear Codes From a Jeep Grand Cherokee

by Dwight Malone

The Jeep Grand Cherokee is a sports utility vehicle that was introduced in 1993 as a way for Jeep to compete against the Ford Explorer. Like all other modern vehicles, the Grand Cherokee has a computer that will alert you to a problem and trigger the "Check Engine" light to illuminate. Once you've corrected the problem, you'll must clear the engine codes. This is a simple procedure that is well within the capabilities of the average Jeep owner.

Step 1

Pop the hood on the Jeep Grand Cherokee by lifting the lever under the dashboard.

Step 2

Release the lever under the front of the hood, and lift up the hood.

Step 3

Locate the battery. It will be on the passenger's side, directly behind the headlight.

Step 4

Place an adjustable wrench around the bolt that is securing the negative battery clamp.

Step 5

Adjust the wrench until it fits tightly around the bolt.

Step 6

Loosen the negative battery clamp, and remove it.

Step 7

Hold the negative battery clamp away from the battery and wait one minute.

Step 8

Place the negative battery clamp back onto the negative battery terminal.

Step 9

Tighten the clamp until it is securely on the negative battery terminal again.

Step 10

Start the Grand Cherokee.

Step 11

Verify that the "Check Engine" light no longer is on.
