Frequently Asked Questions
Where do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship the part until we have this information.
Is this part difficult to install?
No, the physical installation is straightforward for someone with basic mechanical skills. The ECM is located in the LH front of the engine compartment. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old unit. Once this new, programmed unit is installed, you can reconnect the battery and start the vehicle.
Will I need to do any additional programming?
In most cases, no. Because we pre-program the module to your VIN, it should be a plug-and-drive solution. Some vehicles may require a simple security relearn procedure, which can be done without special tools and instructions can easily be found online.
How do I know if the ECM is really the problem?
While the symptoms listed are strong indicators, a definitive diagnosis from a qualified mechanic is always the best course of action. Common diagnostic trouble codes pointing to a bad ECM include P0601, P0606, P060C, and U0100. If your mechanic has condemned the ECM, this is your solution.
Does this fit models other than the Silverado 2500?
Yes. This ECM fits several 2011 GM models, including the Sierra 2500/3500, Silverado 3500 with the 6.0L engine, and even the 2011 Cruze with the 1.4L engine. Our VIN programming ensures it will work correctly for any of the compatible vehicles listed.
