Fault codes

Before the fault codes can be read out enter Service
mode by pressing button D for about 5 sec.
The D indication gives a steady light and indicator on
alarm panel flashes with a orange/red light.
The codes are flashed out on the D button indication.
The fault code consists of three groups of flashes,
separated by a pause of two seconds. A fault code is
obtained by counting the number of flashes in each
group:
Example:
pause
The fault code is stored and can be read as long as the
malfunction remains.
A fault code list, containing information about cause
and effect, is found in the "Fault code list" chapter.
Reading fault codes
1. Reduce engine speed to idling if fault codes are
read when the engine is running. If the engine is
stopped, check that the starter key is in position I
(drive position).
2. Press the diagnostic button D for at least 5 sec-
onds. Release the D button and the yellow indica-
tion lamp will give constant light, which means that
you are in Service mode and fault codes can be
read.
3. The diagnostic button must be depressed to make
the codes flash. Make a note of the three digit
fault code that is flashed out.
4. Repeat the points above. A new fault code is
flashed out if more are stored. Repeat until fault
code 1.1 is flashed.
NOTE! When the fault code 1.1 is flashed, all fault
codes have been read out.
5. Look up the fault code in the fault code list and
take the necessary measures.
Alternatively: If the controls, warning display and
other instrumentation indicate normal function, the
operator can continue the journey and remedy the
malfunction at a later time.
6. To leave Service mode press D button for at least
5 sec. or turn the ignition off.
