NOTE: If a control module or component is suspected and the vehicle is still under manufacturer warranty, refer to the warranty manual (section B1.2) or determine if there is a previously approved special program in effect before installing a new module/component.
NOTE: Generic scan tools cannot read the codes listed or can only read 5-digit codes. To identify the fault, match the five digits from the scan tool to the first five digits of the listed 7-digit code (the last 2 digits provide additional information readable by the manufacturer-approved diagnostic system).
NOTE: When performing voltage or resistance tests, always use a digital multimeter (DMM) with three decimal places of accuracy and a current calibration certificate. When testing resistance, be sure to include the resistance of the DMM leads.
NOTE: Before starting diagnostic programs using Pinpoint tests, check and eliminate basic faults.
NOTE: Inspect the connectors for signs of water ingress and their pins for damage and/or corrosion.
NOTE: If DTCs are logged and the fault is not present after performing the Pinpoint tests, an intermittent problem may be the cause. Be sure to check for loose connections and corroded terminals.
