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.
