Upon connection, ATC will carry out an initial
self-test and the LED light on the front fairing
will light up RED. During the self-test, the
sound of the push rod moving inside ATC
can be heard. When the self-test is
complete, the LED will turn GREEN or
flashing GREEN to signal that ATC is active.
If the LED does not change to GREEN, then
ATC is not functioning correctly. For details
of what to do in this case, see the provided
table on page 15.
Always re-check the ATC LED is green
after any interval during a journey, such
as a service station break.
TROUBLESHOOTING
Should you experience a fault with ATC, the
LED light on the fairing will change colour.
Therefore, refer to the table above and
follow instructions.
If no illumination of the LED is evident, refer
to system requirements and check tow bar
wiring for permanent supply.
In the unlikely event that you receive a red
flashing LED light and disconnecting and re-
connecting the power does not alleviate the
problem, check the push rod position as
detailed below.
Locate ATC on the axle and check to
position of the push rod. (See
photograph right).
If no red line is visible, ATC is not active and
can be driven. However, we recommend that
you contact Al-KO at the earliest
convenience.
If the red line is visible on the push rod, as
shown on the left, the caravan should not be
moved.
Contact Al-KO or a specialist workshop.

PREPARING FOR THE ROAD
Important -
A20 amp fuse is required
on the actual towing vehicle on the
constant 12v supply. Please check with
your Vehicle Dealer/Towbar installer. If
only a single fuse is fitted at the tow bar
a minimum fuse rating of 25 amps must
be used.
Note:
When providing power from an
independent supply e.g. a portable
power pack it is necessary that a
battery rated at least 12V 55 Ah is used
to supply the auxiliary feed. It is also
important that the power supply is fused
at 20 amps.
