NOTE: If a control module or component is suspected and the vehicle remains under manufacturer's warranty, refer to the warranty manual (subsection B1.2) before installing a new module/component, or determine if there is a previously approved special program in effect.
NOTE: Generic scan tools cannot read the codes listed or can only read 5-digit codes. Match the 5 digits from the scan tool with the first 5 digits of the listed 7-digit code to identify the fault (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 electrical connectors for signs of water intrusion and connector posts 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.
For a complete list of diagnostic trouble codes (DTCs) that may be stored in the vehicle, refer to Section 100-00. For additional information, refer to: Diagnostic Trouble Code (DTC) Index - Trouble Code Driver Seat Module (DSM) (100-00 General information, Description and principle of operation).
