NOTE: If there is reason to suspect a failure of the control unit or any component and the vehicle is still under manufacturer's warranty, refer to the Warranty and Procedures Manual before installing a new unit/component (section B1.2) or find out if the procedure for obtaining a prior authorization for repairs is necessary for this case.
NOTE: Universal 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 seven-digit code listed to identify the problem (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 valid calibration certificate. When testing resistance, always consider the resistance of the DMM leads.
NOTE: Before starting diagnostic programs using Pinpoint tests, check and correct basic problems.
NOTE: If DTCs are logged and there is no problem after performing Pinpoint tests, an intermittent problem may be the cause. Always check for loose connections and corroded contacts.
