Inspection and Verification
- Verify the customer concern.
- Confirm which, if any, warning lights and/or messages were displayed on the instrument cluster. NOTE: If any warning lights and/or messages were displayed when the fault occurred, refer to the «DRIVER INFORMATION CHART»(ref-198045-S10264360922005101500000) for DTCs associated with the display, then to the DTC index table for possible sources and actions. Some warnings will appear to clear when the ignition is cycled. This is often because the warning has flagged as a result of one of the vehicle's on-board diagnostic routines having run to detect the fault. If the same routine is not run when the ignition is switched ON, the warning will not reflag until the routine does run. See the DTC summaries for drive cycle routines.
- Visually inspect for obvious signs of mechanical or electrical damage.

FUSE/CIRCUIT RATINGS & LOCATIONS
- Where the Jaguar approved diagnostic system is available, complete the S93 report before clearing any or all fault codes from the vehicle. NOTE: If a DTC cannot be cleared, then there is a permanent fault present that flags again as soon as it is cleared. (The exception to this is P1260, which will only clear following an ignition OFF, wait one minute, ignition ON cycle after rectification.)
- If the cause is not visually evident and the Jaguar approved diagnostic system is not available, use a scan tool to retrieve the fault codes before proceeding to the DTC index chart, or the symptom chart if no DTCs are set. CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Each vehicle is configured to it's own VID block, and substitution of control modules may not only not confirm a fault, but may cause faults in the vehicle being tested and/or the donor vehicle. CAUTION: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result. CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number 3548-1358-00. NOTE: When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to 3 decimal places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads into account. NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step
- If the cause is not visually evident, verify the symptom and refer to «DIAGNOSTIC TROUBLE CODE (DTC) INDEX»(ref-198045-S22867466272005101500000) .
