Chosen Filters
Looking for a Ford BCM, GEM, SJB or BdyCM body control module? This category includes tested body and comfort control modules used in various Ford vehicles. Depending on the model and version, these modules may control central locking, lighting, electric windows, wipers and other vehicle electrical functions. When choosing a replacement unit, the most important step is to compare the original part number with the number shown in the product listing.
At ECUSale you can also find Ford engine control units and electronic modules from FoMoCo. If you are unsure which module fits your vehicle, send us the part number or a clear photo of the original unit.
Ford body control modules are used under different names depending on the vehicle model, generation and electrical system. Common designations include BCM, BdyCM, GEM and SJB. In some Ford vehicles, the body control electronics are integrated with the fuse box and manage several electrical circuits and comfort functions.
When choosing a replacement module, do not rely only on the Ford model, engine or year of manufacture. The safest method is to compare the complete part number on the original module with the number shown in the product listing.
The exact functions depend on the vehicle, equipment level and module version. A Ford BCM, GEM, SJB or BdyCM may be responsible for functions such as:
Depending on the vehicle generation, Ford may use designations such as GEM – Generic Electronic Module, SJB – Smart Junction Box or BCM / BdyCM – Body Control Module. You can also browse our complete BCM, BSI, BSM, SAM, UCH and CAS body control module range.
Problems with a Ford body control module can cause several electrical faults, sometimes affecting more than one system at the same time. Possible symptoms include:
These symptoms do not automatically confirm a faulty BCM. Similar problems may be caused by damaged wiring, connectors, fuses, relays, moisture, poor earth connections or an incorrect power supply. Proper vehicle diagnostics should therefore be carried out before replacing the module.
In some Ford vehicles, the body control module works directly with the fuse box or forms part of the complete fuse box assembly. For this reason, the same type of component may be searched for as a Ford BCM fuse box, Ford GEM module, Ford SJB fuse box, Smart Junction Box or Ford Body Control Module.
When replacing this type of unit, matching the correct part number and module version is particularly important. Two units that look identical externally may have different numbers, software or vehicle configurations.
Depending on the Ford model and type of module, a replacement BCM or BdyCM may require programming, configuration, adaptation or transfer of data from the original unit. Some modules contain configuration related to the equipment installed in a specific vehicle.
Always check the requirements for the specific part number before installation. If you are also looking for an engine ECU, see our Ford engine control units.

How do I find the correct Ford BCM by part number? |
|
The safest method is to compare the complete number shown on the label of your original module with the replacement unit. The Ford model and year alone may not be enough because several BCM versions can be fitted to the same model. |
Does a used Ford BCM body control module need programming? |
|
It depends on the vehicle and the specific module. Some Ford BCM and BdyCM units require programming, configuration or adaptation after replacement. Always check the requirements for the exact part number before installation. |
What is the difference between Ford BCM, GEM, SJB and BdyCM? |
|
These designations are used for Ford body electronics across different vehicle generations. GEM means Generic Electronic Module, SJB means Smart Junction Box, while BCM and BdyCM refer to Body Control Module systems. Their exact functions vary depending on the vehicle and module version. |
What are the symptoms of a faulty Ford BCM or GEM module? |
|
Possible symptoms include problems with central locking, lights, electric windows, mirrors, wipers, indicators or diagnostic communication. Because similar faults can be caused by wiring or power supply problems, the vehicle should be diagnosed before replacing the module. |
Can I replace a Ford SJB or BCM with the same-looking module? |
|
Not necessarily. Modules with identical housings can have different part numbers, software or vehicle configurations. Always compare the identification numbers on the original Ford SJB, GEM or BCM before ordering a replacement. |
Where can I buy a tested Ford BCM, GEM or SJB module? |
