The engine control unit performs the system diagnostics function. When any system problem is detected, it
illuminates the warning lamp and stores the blink code in memory.
The statuses are displayed by the engine check lamp.

ENGINE CHECK lamp
With the DIAGNOSTIC switch, the fault can be read out as a blink code. The DIAGNOSTIC switch and the ENGINE
CHECK lamp can be found on the instrument panel.
Faults are indicated by a blinking or continuous illumination of the ENGINE CHECK lamp.
More precise information regarding all existing faults can be read out in the form of a blink code, only when the
engine is not running, in the following manner:
After actuating the DIAGNOSTIC switch for at least two second, the ENGINE CHECK lamp goes out and the first
faults is output after releasing the DIAGNOSTIC switch displayed as a blink code. Analyse the blink code as per the
table on the engine manual. After the fault blink code has been displayed, the ENGINE CHECK lamp goes out for
five seconds.
Then the next existing fault (i.e. the following one in the fault memory) can be shown by actuating the DIAGNOSTIC
switch again. If the last existing fault has been shown, by actuating the DIAGNOSTIC switch once more the first
fault will be shown again.
