Cardone 73-7809F Body Control Module

Remanufactured Body Control Module for GM Applications

CARDONE Body Control Computer 73-7809F is a remanufactured body control module built to restore electrical control functions with OE-style fit and calibration. It is designed for vehicles that require flash programming after installation, including select Chevrolet Trailblazer, GMC Envoy, Saab 9-7x, Isuzu Ascender, and Buick Rainier applications.

The CARDONE remanufactured body control module line focuses on correcting common failure points found in original units. Each module is reconditioned with critical components re-soldered or replaced, then computer tested for function and reliability before release.

Key Features

• Remanufactured Original Equipment-style body control module
• 100% re-soldering of critical components for stronger electrical connections
• Automated computerized testing for functionality and reliability
• Latest OE software calibration loaded where applicable
• On-car validation routines used to verify form, fit, durability, and performance
• Black plastic housing with 3 rectangle connectors
• Flash programming required on the vehicle after installation
• Fits applications with male and female terminals and snap-in mounting

Product Details

Part number 73-7809F is a remanufactured body control module for GM-platform vehicles that rely on vehicle-specific programming to operate correctly. It is listed for 2005-2009 Chevrolet Trailblazer, 2005-2009 GMC Envoy, 2005-2009 Saab 9-7x, 2005-2008 Isuzu Ascender, 2005-2007 Buick Rainier, 2005-2006 Chevrolet Trailblazer EXT, 2005-2006 GMC Envoy XL, and 2005 GMC Envoy XUV, all without Security System and with OE references 15787809 or 25802312. This part cross-references Cardone 73-7809F for the same application.

What It Helps Address

• Intermittent electrical control issues caused by internal module failure
• Starting or drivability problems after BCM-related faults
• Loss of body functions tied to the control module
• Communication issues after replacing a failed original module
• Programming-related concerns when the correct OE-style module is needed

Installation Notes and Tips

Vehicle-specific flash programming is required on the vehicle after installation, and on-car programming must be completed to prevent drivability and starting issues. Verify the vehicle is equipped without Security System and confirm OE reference numbers before installation. Because this module is flashable, proper programming equipment and procedures are necessary for final setup.

Quality Assurance

CARDONE remanufactures this body control computer at its Philadelphia manufacturing plant using reverse engineering to identify original design weaknesses and correct them during the rebuild process. Critical components are re-soldered or replaced, and each unit is 100% computer tested to help ensure reliable operation. The remanufacturing process also reduces energy and raw material use compared with producing a new part.
