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 ignition switch on, select view, record and erase DTC.

• Start engine and warm it up to the normal operating temperature.

• Select view DTC and data stream.

• 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 :
• Inspect the vehicle for aftermarket accessories that may exceed the Generator System output.

• Inspect the fuses. If an open fuse is found, use the wiring schematics as a guide and inspect the wiring and

connectors for damage.

• Troubleshoot any Engine Control Module (ECM) charging/cranking DTCs before proceeding.

NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
