Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians will use this number to flash the module with the correct software and calibration files directly from GM for your specific vehicle. We handle all the technical work so it’s ready for installation upon arrival.
Is this a true plug-and-play part?
Yes. Because we program the module to your VIN before shipping, it is a direct plug-and-play replacement. No further calibration or programming is required. Simply disconnect the old module, install the new one, and you’re ready to go.
Where is the FSCM located on my vehicle?
On most trucks and large SUVs like the Silverado, Tahoe, or Escalade, the FSCM is located on the driver’s side frame rail, often near the spare tire. On other vehicles like the Traverse or Enclave, it may be on a rear crossmember. Always consult a repair manual for your specific model to confirm the exact location.
Will this fix a Check Engine Light with code P069E?
Yes, P069E (Fuel Pump Control Module Commanded OFF) is one of the most common diagnostic trouble codes indicating a failed FSCM. Replacing your old module with this pre-programmed unit is the correct and most reliable fix for this code.
Is this compatible with part number 20827745 or 20877116?
Absolutely. This module is a direct replacement for multiple GM part numbers, including 20791901, 20827745, 20877116, and 20850927. We program it to function perfectly for your vehicle regardless of which of these original part numbers you have.
