Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure.

1. ACTIVE DTC

NOTE: An external Radio-Frequency Identification (RFID) key (and/or pass/radio key), such as one used to gain access to a 24 hour gym, can cause this DTC to set and create a no start condition. Inspect the customer's key chain for any type of RFID key. If one is not found, question the customer to see if a spare key chain has this RFID key on it or if it was removed from the original key chain before the vehicle was released for service. If a RFID key is present, remove the ignition key from the vehicle and remove the RFID key from the key chain. For GPEC equipped vehicles, disconnect the battery and wait a minimum of five minutes, reconnect and attempt to start the vehicle. For NGC equipped vehicles, turn the ignition on a minimum for one hour, and then attempt to start the vehicle. If the vehicle does not start, continue with the diagnostic test.

1. Attempt to start the engine.

WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.

Yes

- Go To 3

No

- No Response From WCM (Wireless Control Module) Perform the No Responses from WCM diagnostic procedure.

3. SKREEM/WCM TROUBLE CODES SET

Are any DTCs present in the WCM?

Yes

- Testing and Inspection Perform the appropriate diagnostic procedure.

No

- Go To 4

4. VIN PROGRAMMED INTO PCM
1. With the scan tool, display the VIN that is programmed in the PCM.

NOTE: All of the ignition keys for this vehicle must be tested to verify proper operation.

NOTE: If this DTC does not reset, it may have been an actual theft attempt.

1. Turn the ignition on.
2. Verify that the correct VIN is programmed into the PCM and SKREEM/WCM.
