Auto Learn Reprogramming Procedure
The following procedure allows for anyone to reprogram the Body Function Controller (BFC) Learned Data Code without any tools (other than the scan

The Body Function Controller (BFC) will set the DTC 3031 Controller in learn mode when entering the reprogramming procedure.
1. Clear all DTCs
2. Turn the Ignition Switch to the START position.
3. The vehicle will start and then stall.
4. Turn the Ignition Switch to the RUN position until the THEFT SYSTEM indicator turns off (approximately 10 minutes).
5. Turn the Ignition Switch to the OFF position and wait for 10 seconds, then turn the Ignition Switch back to the RUN position.
6. The Body Function Controller (BFC) will learn the new data on the next start attempt.
