Optimize Crucial Functions Of Body Control Module

Open Load Detection is a crucial and important function of the body control module (BCM). By using this function, the body control module can perform open-circuit diagnosis on loads, such as lamps and wiper motors, when the car is running or stopped. Open load diagnosis is an important function of the high-side switch (HSS). This function is mainly realized by measuring the current flowing through the power switch. Usually, the HSS has an inherent function of load current diagnosis. Open load diagnosis can be performed when the load is enabled or disabled. It is conducive not only to safe driving but also to maintenance and repair.
