Fault codes

Working procedure

Try to form a comprehensive view of the
problem. Start by asking the driver the
following:

•

Fault symptoms

•

Conditions in which the fault occurs

•

How often the fault occurs

•

If the warning lamp came on when the fault
occurred

•

If the warning lamp went out by itself when
the fault ceased

•

If the driver has erased the fault codes

Compare them and try to conclude the probable
cause of the fault before taking any other
measures. The fault codes are stored in the order
they were registered.

How to read the fault codes from the diagnostic
lamp is described below.

You can see how to interpret the flashing codes
on the next page.

1

Switch on the power using the starter key.

2

Press the diagnostic switch and note the
number of short and long flashes. You have
now presented one of the fault codes.

3

Repeat point 2 until you have presented all
the fault codes. If the same fault code is
flashed several times, there may only be one
fault in the system.
