Full pressure has been connected to the PTO clutch over 3 seconds, but the PTO
shaft rotation speed is lower than it should be. PTO--clutch may slip. It is possible that
the PTO rpm sensor B7 is faulty. Check in the test mode PTO lever switches S28 and
S29. Check that the switches have not been faulty connected (can be seen in the test
mode). Ensure that the PTO speed parameters P and L are correctly set.

One shuttle direction is engaged and full control has been active over 3 seconds.
Shuttle rotation speed is lower than engine speed in relation to the DPS ratio. One
multi--disc clutch in the DPS or in the Shuttle can slip or one proportional valve
(Y4,Y6,Y17,Y11,Y12) can be trapped. This fault code also appears, if both shuttle
sensors (B12,B13) do not give a signal, when engine revs are over 1600 rpm (
check
the fuse
F22). This fault code is activated at engine speeds over 1000 rpm and in
HiTrol tractors at engine speeds over 1800 rpm. This fault code can also appear, if the
turbine clutch has too much slip (e.g. too little oil in the turbine clutch).

E. Fault code memory (AC 5.2 only)
The fault code memory functions in all tractors, which have
main program version 81 or later. In version 80 the fault code
memory has malfunctions.
For fault codes have been made a memory where can be
checked and removed appeared fault codes. The memory
stores three latest fault codes and their running hours (ac-
cording to the control unit hour counter “L”, not an exact
value).
The fault code memory FI can be activated in the same way
as the test mode FII , see page 370/8.

When the fault code memory has been activated, the display
shows in the lower part of the display the fault codes stored

that after the activation there is an oldest code in the display.
This fault code is visible two seconds and after this is shown
the running hours of the code. The running hours are shown
also two seconds.
If there are many codes in the memory, a line is shown one
second between each codes. Then the next code and the run-
ning hours are shown. When all codes and running hours
have been shown, the first code appears again in the display.
The codes are shown until the current is switched off or the
DPS pre ---programming button is pressed over 4 seconds.
--- if there is no codes in the memory, the line is blinking in the
lower part of the display.
--- the fault code memory can be emptied by pressi ng the DPS
pre ---programming button over 4 seconds, after which the
codes disappear and the line starts to blink.
