Frequently Asked Questions
Do I need to do any additional programming after installation?
No dealership programming is required. The module is pre-flashed to your VIN. However, you will need to perform a simple security relearn procedure, which typically takes 10-15 minutes and can be done without any special tools. We can provide instructions for this process.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you can add your VIN to the ‘notes’ section at checkout, or we will contact you via email to request it. We cannot ship your part until we have the VIN to program it correctly.
How do I know for sure that my ECM is the problem?
While the symptoms listed are strong indicators of ECM failure, it’s always best to have a professional diagnosis performed by a qualified mechanic. This ensures you are replacing the correct part and avoids unnecessary expenses. Common diagnostic trouble codes (DTCs) like P0601, P0606, or U-series communication codes often point to a faulty ECM.
Is this part compatible with other GM vehicles?
Yes, this hardware is used across many GM trucks and SUVs. However, this specific listing is for a 2015-2016 Escalade ESV ECM and will be programmed as such. If you have a different vehicle, like a Silverado or Yukon, please find the listing specific to that model or contact us to ensure correct programming.
What if my original part number is not on your list?
The list of compatible part numbers is extensive but may not be exhaustive. If your part number is different, please contact us with your VIN. We can verify compatibility and ensure you receive the correct, fully functional module for your vehicle.
