AUTOMATIC GEARBOXES
General CF65/75/85 series
1-2
1.1 SYSTEM DESCRIPTION
“Gearbox” warning symbol
When the vehicle ignition is switched on, the
“gearbox” warning symbol will not appear on the
DIP display.
If the gearbox symbol appears in the main
display, it indicates a fault in the gearbox
(shifting), or that the gearbox oil temperature is
too high. The “gearbox” warning symbol in the
DIP will then be displayed in yellow. The selector
keypad LED will also flash three times. The
accompanying fault code can be read in the
selector reading mode (display).
The ECU will block the functions of the selector
and the gearbox will shift to a “safe gear” for the
gearbox. It is important to drive the vehicle to a
safe place as soon as possible and switch the
ignition off. It will no longer be possible to shift
the gearbox to neutral. The ECU will prevent
this.
After approximately 30 seconds, try starting the
engine again and engaging gear. If the error is
one whereby the gearbox must under no
circumstances be shifted, the ECU will no longer
shift the gearbox.
The warning symbol on the DIP display will then
appear in red. The “STOP” warning indicator will
also light up.
Driving is therefore no longer possible!
If the error is one whereby the gearbox may still
be shifted, the warning on the main display will
disappear. The ECU will have recorded the error
as an inactive error.
It is now possible to drive the vehicle again,
even though the error will re-occur after a while.
In this situation, however, it is no longer possible
to shift gear.
