Inspection and verification

WARNINGDanger of accident. Apply the parking brake. Shift the gear selector lever to P . Failure to follow these instructions may result in personal injury.
  1. Verify the customer concern.
  2. 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 table 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.
  3. Visually inspect for obvious signs of mechanical or electrical damage.

Visual Inspection Chart

  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. Where the Jaguar approved diagnostic system is available, complete the S93 report before clearing any or all fault codes from the vehicle.
  3. If the cause is not visually evident and the Jaguar approved diagnostic system is not available, use a fault code reader to retrieve any fault codes before proceeding to the Diagnostic Trouble Code (DTC) Index Chart, or the Symptom Chart if no DTCs are set.
  4. Using the Jaguar approved diagnostic system where available, and a scan tool where not, check the freeze frame data for information on the conditions applicable when the fault was flagged. The format of this will vary, depending on the tool used, but can provide information useful to the technician in diagnosing the fault.

Symptom Chart

CAUTIONWhen probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number 3548-1358-00.

Note. Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

Note. Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

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.
