This process clears the car’s computer memory, which can turn off the light if the problem is fixed or no longer detected. Follow these clear steps to do it safely and correctly.
Prepare Safety Gear
Before starting, wear safety gloves to protect your hands from battery acid. Use safety glasses to shield your eyes from sparks. Ensure your Jeep is parked on a flat surface with the engine off. Remove any metal jewelry to avoid accidental shorts.
Disconnect Negative Battery Terminal
Locate the battery under the hood. Identify the negative terminal, marked with a minus (-) sign and usually black. Use a wrench to loosen the nut on the negative terminal clamp. Carefully lift the cable off the battery post and keep it away from the terminal to prevent contact.

Leave the negative cable disconnected for at least 10 minutes. This pause allows the vehicle’s computer to reset. After waiting, place the cable back on the negative battery post. Tighten the nut securely with your wrench. Start the Jeep to check if the check engine light is off.
