1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step
2. If the cause is not visually evident, use the Jaguar approved diagnostic system or a scan tool to retrieve the fault codes before proceeding to the DTC Index, or the symptom chart if no DTCs are set.
