Reason explanation:
1. protection circuit: the main function of relay control module is to provide current and voltage protection to prevent electrical components from being damaged due to overload or short circuit. By controlling the switch state of the relay, the normal operation and safety of the circuit can be guaranteed.
2. Fault detection and diagnosis: The relay control module can also monitor faults in the circuit and provide corresponding fault diagnosis information through the fault code system. This can help maintenance personnel to locate and solve problems quickly and improve maintenance efficiency.
3. System integration and control: The relay control module can also integrate the control functions of multiple systems to achieve coordination among systems. For example, when a car is started, the relay control module can control the work of the engine and the fuel system at the same time to ensure the smooth starting process.
