Perform the following after completion of a diagnostic repair:

VERIFICATION TEST
1. Reconnect the previously disconnected components and connectors.
2. It may be necessary to obtain the vehicle's unique Personal Identification Number (PIN) assigned to the vehicle. This number can be obtained from the original vehicle invoice or from your Service Manager or Parts Manager.
  NOTE:
  If, during programming, the scan tool instructs to "Enter the vehicle PIN number", care should be taken because the RF Hub will only allow 3 consecutive attempts to enter the correct PIN. If 3 consecutive incorrect PIN's are entered, the RF Hub will Lock Out the scan tool. To exit Lock Mode, the ignition must remain in the Off position for 25 minutes. All accessories must be off. A battery charger connected to the battery during this time period is recommended.
  
  NOTE:
  The PCM stores the secret key information. When the RF Hub needs to be replaced, the secret key information will be retrieved from the PCM and then transferred to the new RF Hub for security use.
3. Turn the ignition on.
4. With the scan tool select: RFH/Radio Frequency Hub.
5. Turn the ignition off.
6. If the RF-Hub was replaced or any un-programmed or new FOBIKs, program all FOBIKs that are to be used with this vehicle. With the scan tool, select "Misc. Functions", "Program Ignition FOBIKs" and follow the instructions on the screen.
  NOTE:
  All FOBIKs that are to be used in this vehicle must remain on the front seat near the console during programming.
7. If the RF-Hub module was replaced, with the scan tool select "Misc. Functions", "RF-HUB Replace" and follow the instructions on the screen.
  NOTE:
  If this vehicle is equipped with a Steering Column Lock Module (ELV/ESCL) (BUX), it must be replaced along with the RF Hub.
8. If equipped, replace and program the Steering Column Lock Module in accordance with the Service Information.
9. Cycle the ignition on then off leaving the key in the On position.
10. With the scan tool, erase all RF Hub DTCs.
11. Operate all equipped RF-Hub functions (Passive Entry, Remote Start, Ignition Positions etc.).
