A communication link between a tractor (102) and trailer (112) is established utilizing existing by dormant tractor and trailer circuitry. In one embodiment of the invention, a tractor communications device (110) has a communications port connected to a turn signal circuit (58). The two communications devices permit communications therebetween over the turn signal circuit as long as the turn signal circuit is inactive, and otherwise inhibits such communications. In another embodiment of the invention, such a communications link is used to transmit a fault signal, relating to an abnormally operating trailer anti-lock brake system, to the tractor (102) for activation of an in-cab ABS warning device.
On établit une liaison de communication entre un tracteur (102) et une remorque (112) en utilisant les circuits dormants de la remorque et du tracteur. Dans un mode de réalisation, un dispositif de communication (110) de tracteur comprend un port de communication connecté à un circuit de signal de virage (582) et un dispositif de communication (122) de remorque présente un port de communications connecté audit circuit de signal de virage (582). Les deux dispositifs de communication permettent les communications entre eux par l'intermédiaire du circuit de signal de virage tant que le circuit de signal de virage est inactif, et sinon inhibent lesdites communications. Dans un autre mode de réalisation de l'invention, ladite liaison de communication est utilisée pour la transmission d'un signal de défaillance, relatif à un système de freinage ABS (124<1>), au tracteur (102) pour l'activation d'un dispositif d'avertissement ABS (130) placé dans la cabine.
