CLAAS 75D8h – Claas Tr1 A57 1 Transmission Module: Range Sensors Simultaneously Open

The system detects that a minimum of two range sensors are simultaneously open, which is not normal as only one should be open at a time. This may indicate a fault in the range engagement contacts or a mechanical issue with the range module.
