What Fault Will Be Displayed If There Is No Internet in the Car?
1 Answers
No internet connection in the car may be caused by a vehicle networking antenna failure or interference signals in the surrounding area. Introduction to Vehicle Networking: Vehicle networking enables integrated intelligent traffic management, dynamic information services, and vehicle control. Solutions for Vehicle Networking Antenna Failures: When the communication distance is shortened, the first step is to test the power supply voltage. During testing, start the car engine and wait for it to reach normal RPM. Then, use a multimeter to measure the voltage entering the car radio, checking both the transmitting and receiving states. Inspect the car battery, including the charging circuit, connections, and wiring, especially the battery terminal clamps. To detect an open circuit in the antenna system, remove the cable connector from the radio and use a multimeter to measure the resistance between the center pin and the outer shell of the connector, which is the resistance between the coaxial cable core and the shield (ground). Under normal conditions, it should show an open circuit.
