Diagnostic Aids

This DTC may be stored as a history DTC without affecting the operation of the B218L Side Object Sensor Module - Left.
Do not replace B218L Side Object Sensor Module - Left based only on DTC B101D being set in history.
If DTC B101D is set as current, replace the B218L Side Object Sensor Module - Left.
Since the left module is the master, if it is replaced, there still may be a problem with the right side as the module may have been unable to report it. Once the left module is replaced, check DTCs and verify operation of the system to assure proper functionality.
