4.1 READING/DELETING ALLISON MD 3060 FAULT CODES
Fault code read function
To enter the fault code reading mode, briefly
press the two arrow keys twice simultaneously.
"D-1" appears on the display, followed by "-".
This means that at that point there are no faults
(active faults) in the system. It also means that no
faults have been registered that were earlier
temporarily present and have now been cleared
(inactive faults). The fault code reading function
can be left by pressing "D", "N", or "R" or the
arrow keys.
If the red lamp lights up while reading a fault
code, this means that there is an active fault in the
gearbox.
No message during reading means that the fault
is inactive.
The ECU can save five active/inactive fault codes
in its memory and show them on the display.
Fault codes consist of two sets of two digits (main
codes and sub-codes). To read the codes
consecutively, the "MODE" button must be
pressed each time.
The letters and digits appear one at a time on the
display.
The hyphen after D4 means that there are no
further faults and that it is therefore not necessary
to look at level D5.
As the ECU can only contain the five most
important codes, the five most important codes
will be seen on D1 to D5. Only when one of the
faults has been remedied will the ECU be in a
position to show a less important fault.
