DTC Index

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2009 Jaguar XKR, 2009 Jaguar XK8, 2008 Jaguar XKR, 2008 Jaguar XK8, and 2007 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number 3548-1358-00. Failure to follow this instruction may result in damage to the vehicle.
NOTE: Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information read by the manufacturer approved diagnostic system).
NOTE: When performing 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.
NOTE: If DTCs are recorded and, after performing the pinpoint tests, the fault is not present, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.
