4.15 AL-KO ATC TRAILER CONTROL SYSTEM
AL-KO ATC is an electronic, emergency braking system for caravans and trailers. It automatically
recognises critical swinging motions and applies the caravan brakes accordingly to regain control of
the car and caravan.
▲
AL-KO ATC is a passive safety product and activates the braking system on the caravan
in unsafe driving conditions. The driver has a responsibility under law to ensure that the
elements of towing safety are met, including driving within the legal speed limit,
consideration of road, weather and other traffic conditions, correct loading and coupling
of the caravan.
ATC is designed to fit only on AL-KO Chassis and is not suitable for non AL-KO Chassis.
ATC only functions for caravans with a rigid towbar.
The electrical connection between the towing vehicle and caravan must be in good working order.
4.15.1 System requirements
ATC draws power from the towing vehicle towbar and requires connection to either:
Twin 7-pin connection
- ATC can be connected via the auxiliary 12S (white/grey) plug and requires
power on pins 3 (earth) and 4 (permanent supply). Please ensure that your vehicle towbar is correctly
connected to ensure correct ATC operation. This can be checked with the use of a multimeter.
13 pin connection
- ATC can be connected via the 13-pin plug and requires power on pins 9 (permanent
supply) and 13 (earth). Please ensure that your vehicle towbar is correctly connected to ensure correct
ATC operation. This can be checked with the use of a multimeter.
4.15.2 Operating instructions
After coupling the caravan correctly to the towing vehicle, connect the 12N and 12S plugs or the 13 pin
plug to the towbar.
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.

Prior to commencing any journey, ensure that the caravan lighting is fully operational and
check the vehicle is loaded appropriately, the nose weight and tyre pressures are correct
and confirm that the caravan is coupled to the car correctly.
