Replacing a Body Control Module (BCM)

When receiving a Motorcycle that has a known bad Body Control Module (BCM), you will need to replace the module and program/marry a new one to the motorcycle. This is a common job that is conducted in many shops and with the help of Centurion, the job has been made easier.

NOTE: If the ECU is locked by another product, you will NOT be able to perform any active settings changes as we will not be able to communicate with the ECU.
  1. Start by installing the new Body Control Module (BCM).
    NOTE: When installing a new BCM, ensure that the bike is turned off so that there is no power getting to the BCM.
  2. Ensure that the IGN is ON, the RUN button is set to ‘Run’ , and the VCM is connected.
  3. Ensure that the battery is at 12v or more and will remain so, for the duration of the module replacement (i.e. Battery Charger).
  4. In Centurion, click the Active Settings button ().
  5. From there, navigate to KeyFob & PIN.
  6. Click 'Get Stored Fob & Pin'
  7. If you do not receive zero’s in all the boxes, like shown below then your BCM is NOT new.
  8. If you DO receive all zero’s then the next step is to program the 5-digit PIN.
  9. Input a 5-digit PIN, and then click 'Program New PIN'.
  10. After the PIN is programmed and you’ve received the status of PASS, navigate to the Module Replacement section.
  11. Click the button () to connect and begin the Module Replacement procedure.
  12. You will be prompted with a window to leave the IGN on and turn the RUN button off, perform these steps and press ‘Ok’ (If the bike is switchless, then leave RUN button on and press Ok).
  13. A second prompt will appear to turn the RUN button back on, and to start the bike and let it run for 5-10 seconds. After performing those steps press 'Ok'.
  14. After hitting zero it will prompt you to turn the IGN off, wait 13 seconds, then turn the IGN on and you should receive a PASS message in the lower text box.

  15. Next, navigate back to the KeyFob & Pin.
  16. Click 'Get Stored Fob & Pin'()
  17. You may now input the 24-digit codes for the Hands Free KeyFobs to assign them to the bike.
  18. After receiving the status PASS, navigate to the BCM: (Enable/Disable) page.
  19. From here, you can enable any of the features that your motorcycle’s BCM supports.
  20. After enabling the features wanted, you have completed the BCM replacement procedure.
