NOTE: If a control module or component is suspected and the vehicle continues to be covered by the manufacturer's warranty, refer to the warranty manual before installing a new module/component (section B1.2) or determine if there is any previously approved special program in operation.
NOTE: Universal Scan Tools cannot read the listed codes or can only read 5-digit codes. To identify the problem, match the five digits from the scan tool with the first five digits of the seven-digit code listed (the last 2 digits give additional information read by the diagnostic system approved by the manufacturer).
NOTE: Always use a digital multimeter when performing voltage or resistance tests (DMM) accurate to three decimal places and with a modern calibration certificate. When checking resistance, be sure to consider the resistance of the DMM wires.
NOTE: Before starting diagnostic programs using Pinpoint tests, check and correct basic problems.
NOTE: Inspect the connectors for signs of water intrusion and their pins for damage and (or) traces of corrosion.
NOTE: If DTCs are logged and there is no problem after performing Pinpoint tests, an intermittent problem may be the cause. Be sure to check for loose connections and corroded contacts.
