Calibration Update
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.
Note. If calibration fails when calibrating the driver seat module (DSM), disconnect the vehicle battery, wait 1 minute, connect the battery and complete the calibration update.
