Product Details

Cardone remanufactured electronic and powertrain control modules are reverse engineered to identify common failure points and correct original design weaknesses. Critical components are re-soldered or replaced at Cardone’s Philadelphia manufacturing plant, and each unit is computer tested before release. For GM and other supported applications, this ECM helps restore proper fuel, spark, and engine control functions after a failed original module. This part number, 77-3636F, is a direct-fit electronic control solution for vehicles such as the Chevrolet Cruze, Chevrolet Sonic, GMC Sierra 2500 HD, and Buick Encore.

This part cross-references 12643636 and 12668866 for the same application.

Common Issues This ECM Can Address

• Check engine light that remains on after reset
• Engine shutting off unexpectedly
• Loss of spark or fuel injection control
• Fuel pump pulse loss or intermittent starting problems
• Driveability issues traced to a failed control module

Installation Notes

• Flash programming is required after installation.
• Verify the original failure cause before replacing the module; poor grounds, power supply issues, wiring faults, and shorted relays or solenoids can damage the replacement.
• Some GM applications require transfer of a knock module or calibration module from the original unit.
• Some GM vehicles use VATS, Pass Key, or Pass Lock anti-theft systems.
• Chrysler models 1996 and newer require VIN programming; Ford applications may require a PATS reset depending on the vehicle.
