Calibration Update
WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Some modules are designed to be flashed or reflashed with completely new software packages. This process of reflashing the module is a calibration update.
A calibration update should be carried out only upon notification (such as a Technical Service Bulletin [TSB]). Also, if a module sets DTC U2050, this indicates no application is present and reflashing of the software application is required. If a module sets DTC U2051, this indicates no calibration is present and reflashing of calibration is required.
