NOTE:
If this Electronic Control Unit (ECU) is being replaced with a new unit, a diagnostic scan tool MUST be used to determine if alignment of the PROXI configuration data into the new ECU is needed.

- Turn the ignition OFF and then to the RUN position and confirm that any found DTCs are now cleared.
- Select the BCM "ECU view".
- Select the "Misc Functions" menu and perform the "PROXI alignment" procedure.
- Select the Radio Frequency Hub (RF-Hub) "ECU View".
- Select the "Misc Functions" menu and perform the "Update Front and Rear Axle Nominal Tire Pressure Values" procedure to program the tire pressure threshold values.
