Reading off the fault code via the
diagnostics lamp on the instrument
panel, CIU
When the system has detected a functional fault, the
diagnostic lamp starts flashing. If you press and re-
lease the diagnostics button, a fault code will be
flashed out.
The fault code consists of two groups of flashes, sep-
arated by a pause of two seconds. The fault codes are
read by counting the number of flashes in each group.
Example : pause = Fault code 2.4
The fault code is registered and can be read off as
long as the fault exists. You can find information con-
cerning causes, reaction and remedies in chapter
“Fault codes”.
Read the fault code as follows:
1. Press the diagnostics button.
2. Release the diagnostics button and note the fault
which is displayed as flashes.
3. Repeat steps 1-2. A new fault code will be flashed
out if there are any more registered. Repeat until
the first fault code is repeated.
NOTE: When the first fault code is shown again, all
fault codes have been shown.
If you press the diagnostics button after a fault has
been rectified and the fault codes erased, code 1.1 will
be shown “No faults”.
