DTC Index
• NOTE: If a control module or component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval program is in operation,
before the replacement of a component.
• NOTE: Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the
scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read
by the manufacturer-approved diagnostic system).
• NOTE: When performing 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: Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.
• 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.
