• Code retrieval and review
• Freeze-frame data analysis
• Cause-focused diagnosis

An OBD-II code identifies the circuit or system that reported the fault, not necessarily the failed part. The cause could be minor, such as a loose gas cap, or more serious. Diagnosis is needed before selecting a repair.

• The light may stay on or flash
• Rough idle or hesitation may occur
• Fuel economy may drop or an emissions test may fail

The same diagnostic code can have several possible causes, so code retrieval alone does not identify the failed component. A technician should test the related circuit and system before a repair is recommended for your 2025 Jeep Grand Cherokee.

• Oxygen sensor or fuel-mixture concerns
• EVAP system leaks or faults
• Misfire, airflow, or catalytic converter concerns

• Steady light: drive cautiously to service
• Flashing light: stop driving
