Removing The Negative Cable
First, locate the battery in your Jeep Cherokee. The battery is usually under the hood. Use a wrench to loosen the nut on the negative terminal. The negative cable is usually black and marked with a minus sign (-). Carefully remove the cable from the terminal. Make sure it doesn’t touch any metal parts.
Timing Considerations
Leave the negative cable disconnected for at least 30 minutes. This allows the vehicle’s computer to reset. Some experts recommend waiting up to an hour. After the wait, reconnect the negative cable. Tighten the nut securely.

Reattaching The Negative Cable
First, locate the negative cable you previously removed. Hold the cable firmly and bring it close to the negative terminal. Align the cable end with the terminal to ensure a proper fit.
Next, place the cable end onto the terminal. Tighten the clamp using a wrench or a suitable tool. Ensure the clamp is securely tightened to avoid any loose connections.
Ensuring Secure Connection
After reattaching the negative cable, it’s essential to check the connection. Make sure there are no gaps between the cable end and the terminal. A secure connection is vital for the proper functioning of your Jeep Cherokee’s computer.
Use your hand to gently tug on the cable. If it feels loose, tighten it further. A loose connection can lead to electrical issues. Once you’re confident the connection is secure, close the hood of your Jeep Cherokee.
