DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Connect the X-431 scan tool to the diagnostic connector (DLC) - use the most current software available, press
the POWER key to start the X-431.
• Turn ignition switch on and record and erase DTC.
• Start engine and warm it up to the normal operating temperature.
• With the scan tool, select view DTC and data stream.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 03 Electronic Engine Controls for more information.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
