A replacement control module is a paperweight until it is programmed to the vehicle. Auto Care Plus performs module programming, flashing, and software updates with manufacturer software and secure gateway access at our NH, MA and ME shops — or on site at yours. This is the work most independent shops have to send to the dealer. We do it here.

Modern vehicles have dozens of computer modules — engine, transmission, body, ABS, airbag, infotainment, and more. A new or replacement module comes blank or with generic software, and it has to be flashed with the correct calibration file for your specific VIN and then configured to the vehicle's options.
Most modules are married to the vehicle's VIN and immobilizer, so a module from another car will not communicate correctly, if at all. Some can be reprogrammed to a new VIN and some absolutely cannot. We will tell you which category yours falls into before you spend money on a used part.

Sometimes a reflash with updated software resolves a driveability problem outright — manufacturers release updates to fix known issues, and a TSB reflash is often the correct repair. Other times the module has genuinely failed. Proper diagnosis tells us which, and it can save you the cost of a module you did not need.
Most programming takes one to two hours including diagnosis, setup, and post-programming verification and relearns. Some modules and some vehicles take longer, particularly when ADAS calibration is required afterward.
