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 DSM, disconnect the vehicle battery, wait 1 minute, connect the battery and complete the calibration update.
