2.3 ELECTROPNEUMATIC DOWNSHIFT PROTECTION VALVE
The electropneumatic downshift protection valve
receives a certain frequency value relating to the
vehicle speed from the VIC.
If this value is too high, the connection between
the electropneumatic downshift protection valve
and earth will be broken. Despite the pneumatic
command from the range group operating switch
to connection point (4) on the electropneumatic
downshift valve, it is not now possible to switch to
the low range.
The system pressure to connection point (1) on
the electropneumatic downshift protection valve
is only available when the gear lever, and hence
also the neutral position valve, is in the neutral
position.
