AL-KO ATC Trailer Control System

Please refer to the AL-KO ATC handbook supplied with your caravan for more details and
fault finding AL-KO ATC is an electronic, emergency Control system for caravans and trailers.

It automatically recognises critical swinging motions and applies the caravan brakes accordingly to regain control of the caravan and car.
AL-KO ATC is a passive safety product that 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.

In order for the ATC to function correctly the electrical connection between the towing vehicle and caravan must be in good working order.
Upon connection of the 13 pin connector the ATC will carry out an initial self-test and the LED light on the ‘A’ frame cover 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.

ATC LED Light

WARNING: If the LED does not change to green, then ATC is not functioning correctly.
Do not tow the caravan until it has been rectified. Please refer to the AL-KO ATC handbook for more details and fault finding.

Note: Please be aware your ATC is ‘live’ all of the time your 13 pin connection is made.
If the car and caravan are stood for a long period of time (eg. ferry crossing) the ATC will continue to draw power from your battery.
