Body Control Module (BCM): Notes

WARNING: This page is about a different car, the 2013 Lincoln MKX and 2013 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: When any vehicle module is being programmed, connect an external battery charger to make sure that the module programming is completed without the interruption due to the load-shedding feature becoming active. The external battery charger must maintain a system voltage above 13 volts. This can require a charger setting higher than the lowest charge setting. The external battery charger negative connection must be made to an engine or vehicle chassis ground and not the negative battery terminal. If the connection is to the negative battery terminal, load-shedding cannot be prevented from being invoked and module programming may be corrupted. After charging has begun, start the engine to clear any load shed states and then turn the engine off and proceed with programming.

NOTE: If installing a new module, it is necessary to upload the module configuration information to the scan tool prior to removing the module. This information must be downloaded into the new module after installation.

NOTE: If installing a new BCM, all vehicle keys are erased during the parameter reset procedure. For vehicles without Intelligent Access (IA) verify at least 2 of the vehicle keys are available prior to carrying out this procedure.
