DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
•
Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn the ignition switch on, with the scan tool, view and erase stored DTCs in the Immobilizer control module.
• Try to start the engine.
• Turn the ignition switch off, and wait a few seconds, then turn the ignition switch on.
• With the scan tool, view active DTCs in the Immobilizer control module.
• If the DTC is detected, the 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 15 Body & Accessories for more information).
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
