NOTE: If there is reason to suspect a control module or any component is defective and the vehicle is still under manufacturer's warranty, refer to the warranty and procedures manual before installing a new module/component. (section B1.2) or find out whether the procedure for obtaining prior authorization for repairs is mandatory in this case.
NOTE: Generic scan tools cannot read the listed codes or can only read five-digit codes. In this case, match the five digits from the scan tool with the first five digits of the listed seven-digit code to identify the fault. (the last 2 digits provide additional information readable by a 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 valid calibration certificate. When testing resistance, always include the resistance of the DMM leads.
NOTE: Before starting diagnostic programs using Pinpoint tests, check and eliminate basic faults.
NOTE: If DTCs are set and the fault is not present after performing the Pinpoint tests, the cause may be an intermittent fault. Always check for loose connections and corroded terminals.
