Quality Used Auxiliary Computer Boxes You Can Trust

Modern vehicles are a network of dozens of computers. While the engine computer runs the motor, the auxiliary computer boxes (such as the Body Control Module, Transmission Control Module, or ABS Module) control everything else—from your power windows and door locks to shifting gears and stopping safely.

At Falcon Car Parts, we specialize in providing genuine, used OEM non-engine modules. Every module in our inventory is carefully extracted from dry, un-flooded donor vehicles. We rigorously inspect the external housing and the delicate connector pins to ensure the unit is physically sound and ready to be flashed by your technician.

  • Corrosion Free: Rejected if any water damage or oxidation is detected on the terminals.
  • OEM Circuitry: Genuine factory boards offer far better longevity than rebuilt aftermarket units.
  • Housing Intact: No cracked cases or broken mounting tabs, ensuring a secure seal from the elements.

Non-Engine Modules for Every System

We stock a vast array of exact-match auxiliary computer boxes for all makes and models.

Body Control (BCM)

The hub for interior electronics. Manages lighting, windows, power locks, security systems, and wiper functions.

Transmission (TCM)

Dedicated computer that shifts the gears in your automatic transmission based on speed, load, and throttle inputs.

ABS / SRS Modules

Safety critical modules. The ABS controls anti-lock braking and traction, while the SRS module manages airbag deployment.

Our 6-Point Quality Check for Auxiliary Modules

Electronic components require the strictest standards. Every used module sold by Falcon passes the following checks:

  • 1. Hardware Number Verification: We check the manufacturer stickers to ensure the service numbers match your request perfectly.
  • 2. Terminal Pin Inspection: Connectors are examined under light to ensure no pins are bent, burnt, or missing.
  • 3. Water & Moisture Check: We look for telltale signs of water intrusion (white or green oxidation), especially common in BCMs mounted near the floorboards.
  • 4. Odor / Short Circuit Test: We sniff the unit for distinct burnt electrical odors which indicate a fried internal motherboard.
  • 5. Casing Integrity: The aluminum or plastic housing is checked for heavy dents or cracks that could compromise the internal board.
  • 6. Donor Vehicle Vetting: We ensure SRS/Airbag modules come from un-deployed vehicles, and avoid parts from flood-damaged cars.

Common Questions About Buying Non-Engine Computer Boxes

This category includes all auxiliary electronic control modules outside of the main engine computer. It primarily refers to Body Control Modules (BCM), Transmission Control Modules (TCM), ABS Modules, and Airbag/SRS Modules.

Used auxiliary modules typically range from $40 to $250. The price depends heavily on the specific type of module (BCM, TCM, etc.) and the make and model of your vehicle.

The BCM acts as the central hub for your vehicle's interior and body electronics. It controls functions like power windows, door locks, interior/exterior lighting, and the security/immobilizer system.

Signs of a bad TCM include erratic shifting, the transmission getting stuck in one gear (limp mode), delayed engagement when shifting into Drive or Reverse, and an illuminated Check Engine or Transmission light.

In most modern vehicles, yes. Modules like the BCM and TCM usually need to be flashed or programmed to your specific VIN so they can communicate seamlessly with the main Engine Computer on the CAN bus network.

Yes, provided the module is sourced from a vehicle that did not have its airbags deployed, or if it has been professionally cleared/reset. We thoroughly vet our donor vehicles for safety.

A failing ABS module will typically trigger the ABS light on your dash. While your normal brakes will still work, you will lose the anti-lock braking safety feature and likely your traction control system.

Absolutely. Vehicle electronics are highly specific. You must match the OEM hardware number on your original module exactly to ensure the replacement unit works correctly in your car.

OEM modules feature high-quality factory circuit boards designed to withstand the heat and vibration of your specific vehicle. Aftermarket electronics are notorious for communication errors and premature failure.

Since we are based in Clifton, NJ, we offer rapid 1-2 day delivery for local customers and fast, secure nationwide shipping for those outside the Tri-State area.
