How to handle the u0100 trouble code?

[VonMolly]

u0100 trouble code is caused by the loss of communication between the control module or powertrain control module, mostly due to circuit failure. It is recommended that car owners go to a 4S shop for repair when encountering this fault. The engine control module, commonly referred to as the ECU, is the brain of the car engine. The ECU collects data from various sensors, processes it, and then controls the engine operation through actuators. Without the ECU, the engine cannot function properly. The ECU has self-diagnosis and protection functions. When a system fault occurs, it can automatically record the fault code in RAM and take protective measures, reading substitute programs from the inherent program to maintain engine operation. At the same time, these fault messages will be displayed on the dashboard and remain lit, allowing the car owner to detect the problem in time.
