Principle of High Beam Linkage Module
By connecting to the CAN Low and Can High cables and creating a power supply for the adapter, the module determines the high beam function and outputs this via the violet cable. This page explains how the new lighting assistance systems work and the key aspects to bear in mind when testing and adjusting them. Electronic technology has advanced so that an electronic control unit (ECU) is required to control the functions of full LED automotive headlights. With modern headlights with LED or xenon technology, it is often difficult or impossible to pick up a control signal for the high beam.
