CIU (Control Interface Unit)

When the system detects a malfunction, the
diagnostics lamp flashes. If the diagnostics button is
pressed and then released, a fault code is flashed out.
The fault code consists of two 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 = fault code 2.4
The fault code is stored and can be read off as long as
the malfunction remains. Information about causes,
effects and actions required is available in the Fault
Code chapter.
Do as follows to read off the fault code:
1 Press the diagnostics button.
2 Release the diagnostics button and note down the
fault that is flashed out.
3 Repeat items 1–2. A new fault code will be flashed
out if more faults are stored. Repeat until the first
fault code reappears.
NOTICE! When the first fault code reappears, all fault
codes have been read off.
If the diagnostics button is pressed after the fault has
been rectified and the fault codes have been erased,
code 1.1 "No fault" will be displayed.
