Extended Power Module [BECMB]

WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

The BECMB provides system voltage to the RCM and PAD indicator when the ignition is ON. Additionally, the BECMB is designed to ensure that the RCM remains powered on if the ignition is turned off while the vehicle is moving at a speed greater than 4 km/h (2.5 mph).

If the ignition signal is active / high while the vehicle is travelling at a speed above 4 km/h the BECMB maintains system voltage on the RCM and PAD indicator power supply circuits. If the ignition signal is lost, missing, or below a certain threshold while the vehicle is travelling at a speed above 4 km/h (2.5 mph), the BECMB maintains system voltage on the RCM and PAD indicator power supply circuits and a telltale appears in the IPC. If the vehicle speed rises above the threshold again, the BECMB does not reactivate the power supply to the RCM and PAD indicator. They remain off until the ignition is turned on again.

If a vehicle is parked, with the ignition off, the BECMB does not provide power to the RCM and PAD indicator. If the vehicle begins to move, while the ignition is still off, the BECMB does not power the RCM or PAD indicator.

When the vehicle has been started using the remote start feature (if equipped), the ignition status is off, but the BECMB powers the RCM in order to detect a collision and disable the fuel pump, if necessary.
