During operation
If the diagnostic lamp starts to flash during operation:
1. Reduce engine speed to idling.
2. Press the diagnostic button (for 1-3 seconds).
3. Release the diagnostic button and make a note of
the diagnostic trouble code (DTC) that is flashed
out. Please refer to “Reading fault codes” below.
4. Look up the fault code in the fault code list and
take the necessary measures. Please refer to the
“Fault codes” chapter.
If the diagnostic lamp starts to flash, the engine will
be emergency stopped.
IMPORTANT! In VE engines, there is a func-
tion in the system which makes it possible to
start the engine again and run it for about 25
seconds. This is so that the vehicle can be
moved from a railway level crossing etc.
Reading fault codes
Fault codes can either be read via:
- The VODIA tool (including the Penta EDC4 soft-
ware). Please refer to the “VODIA User’s Guide”
for advice on use.
- Diagnostic lamp
- CAN
Diagnostic lamp
If the diagnostic lamp is illuminated or flashes, a fault
code can be read by pressing the diagnostic button
(for 1-3 seconds) and then releasing it. The diagnos-
tic lamp goes out, and a fault code is then flashed
out.
The fault code consists of three groups of flashes,
separated by a pause of two seconds.
The first and third group consist of short flashes (0.4
s). The second group consists of long flashes (0.8 s).
A fault code is obtained by counting the number of
flashes in each group.
Example
: (2 short) pause (2 long) pause
(1 short) = Fault code 2.2.1
The fault code is stored and can be read as long
as the fault remains. You can find information about
cause, reaction and actions in the fault code list.
Please refer to “Fault codes”.
Read as follows:
1. Press the diagnostic button (for 1-3 seconds).
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.
NOTE! When the first fault code is repeated, all fault
codes have been read out.
When all faults have been rectified:
1. Turn the ignition on and off.
2. Press the diagnostic button (for 1-3 seconds) to
check whether any faults remain.
3. If there are no active faults, the diagnostic lamp
will give two short flashes, in other cases the
remaining non-rectified faults will be flashed out
again.
