If the check engine light is on in your 1997 Jeep Grand Cherokee, it indicates that the vehicle's onboard diagnostic system has detected an issue. Common causes can include problems with the engine, transmission, emissions system, or even minor issues like a loose gas cap. It's advisable to use an OBD-II scanner to retrieve the trouble codes, which can help pinpoint the exact problem. Once you have the codes, you can either troubleshoot the issue yourself or take the vehicle to a mechanic for further diagnosis and repair.
