The long flashes (1 s) that come first represent
units of ten. The shorter flashes (0.3 s) that
follow represent units of one.
The example on the right symbolises fault
code 25.

A single, very long flash (4 s) means that there
are no fault codes stored in the memory.

How to erase fault codes
The EDC control unit memory is able to store
40 fault codes.
The fault codes are stored in two different
places in the control unit. Erasing with the
diagnostic switch erases the fault codes that are
flashed on the diagnostic lamp.
Scania Diagnos is used to erase both fault code
memories at the same time.
How to erase fault codes during delivery
inspection
How to erase fault codes that are flashed on
the diagnostic switch
How to erase fault codes that are flashed on the
diagnostic lamp is described below. The fault
codes will then continue to be stored elsewhere
in the control unit — These fault codes are
deleted using Scania Diagnos.
1
Start and switch off the engine once so that
a shutdown test is carried out. Wait until
the EDC warning lamp has gone out.
2
Press the diagnostic switch while turning
the starter key to drive position for 3
seconds. Resetting is then complete.
3
Start the engine and check that the warning
lamp goes out.
4
Press the diagnostic switch. The fault code
memory should be empty; only one long
flash should be seen.

Flashing codes
This is a list of the flashing codes which can be
read and the fault codes to which they
correspond. EDC S6 differs from previous EDC
systems in that one flashing code corresponds to
a number of different fault codes.
