Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostic Test
If other electronic modules need to be replaced, besides the RF-Hub, see the "Replacement and Programming Order Guide" before proceeding. Refer to STANDARD PROCEDURE .
For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .
Perform the following after completion of a diagnostic repair:
- VERIFICATION TEST
- Reconnect the previously disconnected components and connectors.
- 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 On position for 25 minutes. All accessories must be off. A battery charger connected to the battery during this time period is recommended.
