Diagnostic function

Reading fault codes via the diagnostic
lamp on the instrument panel, CIU
When the system has discovered a malfunction, the
diagnostic lamp starts to flash. If the diagnostic but-
ton is depressed and then released, a fault code is
flashed out.
The fault code consists of two groups of flashes, sepa-
rated by a pause of two seconds. A fault code is ob-
tained by counting the number of flashes in each group.
Example:
pause
= Fault code 2.4
The fault code is stored and can be read as long as the
malfunction remains. You can find information about
cause, reaction and actions in the “Fault Code” chapter.
Read the fault code as follows:
1. Press the diagnostic button.
2. Release the diagnostic button and make a note of
the fault that is flashed out.
3. Repeat items 1-2. A new fault code is flashed out
if more are stored. Repeat until the first fault code
is repeated.
4. Look up the fault code in the “Fault Code” chapter
and take the recommended measures.
NOTE!
When the first fault code is repeated, all fault
codes have been read out.
If the diagnostic button is pressed after the fault has
been mended and the fault codes have been erased,
code 1.1 “No fault” will be displayed.
