Customer statement / workshop findings: Diagnostic Trouble Code (DTC) U040100 50273/C461 Invalid Data Received From ECM/PCM \"A\" stored within the Transmission Control Unit. Technical background: During Adaptive Cruise Control (ACC) brake to stop events, it is possible for the brake pressure to decay at a rate outside of specified parameters, DTC - U040100 50273/C461 Invalid Data Received From ECM/PCM \"A\" will therefore be stored within the Transmission Control Unit.
