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

1. ACTIVE DTC

NOTE: Diagnose any Can C or Can B failures before continuing.

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 NCG 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.

6. With the scan tool, read the PCM DTCs.

Does the scan tool display this code?

Yes

- NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage or terminal push out. Repair as necessary. Replace and program the Powertrain Control Module.

- Perform the RF HUB VERIFICATION TEST. RF Hub Verification Test

No

- Test Complete.

6. IGNITION KEY

NOTE: You must obtain the SKREEM pin number.

NOTE: This DTC could have been set if the RF Hub harness connector was disconnected or if the RF Hub was replaced recently.

NOTE: All keys that the customer uses for this vehicle must be tested to verify they are operating properly.

1. Ignition on, engine not running.
