Restore Control and End Electrical Frustrations in Your GM Truck
Are you tired of playing whack-a-mole with your truck’s electronics? One day the power windows have a mind of their own, the next your radio won’t turn off, or worse, you’re faced with a no-start condition that leaves you stranded. These baffling and inconsistent issues often point to a single culprit: a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can wreak havoc. This fully programmed Body Control Module, compatible with part numbers 22846364, 22737275, and 22846365, is the definitive solution to restore order and reliability to your vehicle.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2013 Sierra 3500 that rolled into my bay with a list of complaints that sounded like a poltergeist had taken up residence. The dome lights would flicker, the driver’s door module would randomly stop responding, and the customer reported the security light would stay on, preventing the truck from starting. A scan tool showed a slew of U-codes (U0140, U0155, U0164), indicating a loss of communication between various modules. Instead of chasing individual components, experience pointed me straight to the BCM. After swapping it with a known-good unit, every single phantom issue vanished. This isn’t an isolated case; it’s a classic failure pattern for these workhorse trucks. This pre-programmed module is designed to solve that exact diagnostic headache.
Is Your Truck Showing These Symptoms?
A failing BCM doesn’t always trigger a check engine light. Instead, it creates a variety of confusing electrical problems. If you’re experiencing any of the following, your BCM is the likely cause:
- âś” Power windows, door locks, or mirrors operating intermittently or not at all.
- âś” Interior or exterior lights staying on, flickering, or not turning on.
- âś” Instrument cluster gauges behaving erratically or going dark.
- âś” The radio or infotainment system malfunctioning.
- âś” Remote keyless entry (RKE) failing to work.
- âś” A persistent security light and a no-crank, no-start condition.
- âś” Diagnostic Trouble Codes (DTCs) indicating loss of communication, such as U0140, U0151, or U0168.
The Smart Solution: A VIN-Programmed 2012-2014 Sierra BCM
The biggest hurdle in replacing a BCM has always been the expensive and time-consuming programming required at a dealership. We eliminate that step entirely. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash this module with the latest, most stable GM-approved software specific to your truck’s configuration. It arrives at your door ready for installation, saving you hundreds in dealer fees and diagnostic time. Plus, with our no-core-charge policy, you can keep your old part without the hassle of shipping it back.
Your Straightforward BCM Installation Guide
Replacing the BCM is a manageable job for a DIY enthusiast with basic tools. It’s located under the driver’s side of the dashboard, near the steering column.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10-15 minutes to allow all systems to power down completely.
- Access the Module: Remove the lower dash panel (knee bolster) below the steering wheel. It’s typically held in by a few screws or clips.
- Locate the BCM: Identify the Body Control Module. It’s a black plastic box with several large multi-pin electrical connectors.
- Disconnect and Remove: Carefully release the locking tabs on each electrical connector and unplug them. Once all connectors are free, unclip or unbolt the module from its mounting bracket and remove it.
- Install the New BCM: Mount your new, pre-programmed module onto the bracket. Reconnect all electrical connectors firmly, ensuring each one clicks into place.
- Final Steps: Reinstall the lower dash panel and reconnect the negative battery terminal. Turn the key to the ‘ON’ position (without starting the engine) and test all body functions like windows, locks, and lights.
Important Post-Installation Notes
While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ procedure after installation. In most cases, the vehicle will operate perfectly. However, please be aware of these possibilities:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control operation.

Frequently Asked Questions
Frequently Asked Questions
Do I need to take this BCM to the dealer for programming?
No. We program the module to your vehicle’s VIN before shipping it. It is a plug-and-play installation, though some minor relearn procedures may be needed post-install as noted above.
Where is the BCM located on my 2013 Silverado or Sierra?
The Body Control Module is located under the driver’s side dashboard, attached near the steering column and above the pedals.
What happens if my airbag light comes on after I install it?
This indicates the new BCM needs to be electronically synced with the vehicle’s airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes.
Is there a core charge for my old BCM?
No, there is absolutely no core charge. You can keep your old module, saving you the time and expense of returning a core.
Will this fix my power window and door lock problems?
Yes, in the vast majority of cases, intermittent or non-functional power windows, locks, and lights are classic symptoms of a failing BCM. This part is designed to be the direct solution for those issues.
What part numbers does this module replace?
This BCM is a direct replacement for part numbers 22846364, 22737275, and 22846365.
