DTC Index
• NOTE: If a module or component is suspect, and the vehicle remains under the Manufacturers warranty, refer to the
Warranty Policy and Procedure manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component.
• 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 extra
information read by the manufacturer-approved diagnostic system).
• NOTE: When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three
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, a fault is not present, an intermittent concern may
be the cause. Always check for loose connections and corroded terminals.
For a complete list of all diagnostic trouble codes that could be logged on this vehicle, please refer to section 100-00.
