What are the reasons for the Lexus USB port not responding when charging?

[OscarFitz]

Lexus USB port not responding when charging may be due to the following reasons: 1. The original USB port does not support charging function: The car's USB port can connect to a phone for various functions, but some USB ports only provide data exchange with the car's entertainment system, so the current is only 0.5A, which cannot support the car charging function. 2. Car USB port failure: If the original USB charging port supports the charging function but suddenly stops responding, after ruling out issues with the phone and data, you should check the car's USB port. Generally, when this fault occurs, the first thing to check is the power supply fuse of the USB port, and replace it with a new fuse if necessary. If the fuse is not damaged, or the USB port does not have an independent power supply fuse but is powered by the car's entertainment system, then you should check the power supply of the USB port. If there is power supply, the USB port itself may be damaged. If there is power supply, you should check the wiring or the control unit (commonly known as the car computer) of the car entertainment system that provides the power supply for damage.
