Detection: Error is set if incompatibilities between EEPROM dataset and drive software, hardware or bootloader versions are found, if there are unplausible data in the dataset, or if EEPROM has a failure. In case of the internal DTC is 0x022201 (Axle Mass Slope : Invalid configuration) the exact root cause can be identified in the DTC's freeze-frame information ('snapshot data'). Snapshot data parameter 'SetFault Additional Parameter' indicates the reason for the fault: (0x00) Front Axle - No valid front axle found (0x14) Primary Rear Axle - No valid axle found (0x15) Primary Rear Axle - Axle Load Estimation (ISC-based) is configured for any axle, except for the primary rear axle. (0x32) General Setup - Parameter DisableMassEstimation must not be true, if TCM is available. MassEstimation cannot be disabled if TCM is available. (0x33) General Setup - Axle Load Estimation is configured, but ISC or STEP4 is not configured. (0x34) General Setup - Minimum Axle Loads are higher than Maximum Axle Loads. Check configured minimum/maximum axle loads and Bodybuilderload. (0x35) General Setup - Minimum/Maximum Axle Loads for an available axle is not configured.

Cause: HW is not compatible with the SW Incorrect data in the dataset Dataset inconsistent to ECU Damaged central ECU (EEPROM)
