The reason for the non-illumination of the Haval H2 center control screen is the loosening of the connecting wires behind the center control screen. The following is a related introduction to the Haval H2: 1. Configuration: The Haval H2 is also equipped with intelligent tire pressure monitoring system, reverse image, constant speed cruise and other offline auxiliary systems, which comprehensively ensure the safety of the crew, make it easier for the driver to drive safely, and take them to any interesting place. 2. Function: It is equipped with ESP body stability system, with TCS traction control, HHC slope assistance, RMI anti-side rotation system, HDC steep slope loosening and other functions. Combined with the EPB electronic handbrake configuration, driving is safer.
I encountered this exact situation last time when repairing my friend's Haval H2. Don't worry yet - the most common cause is a blown fuse. Check fuse number F29 in the fuse box near your left foot in the driver's position - it specifically controls the central console power supply. Remove it to see if the thin wire in the middle has melted. Then inspect the wiring connections, especially whether the plug behind the screen has come loose. Humid summer weather can also cause short circuits, particularly noticeable in vehicles with modified reverse cameras. Also try holding down the power button to reboot. If that doesn't work, you might need to consider a faulty screen driver board. Just last week I handled a case where a swollen capacitor on the driver board caused black screen - replacing the circuit board fixed it for about 300 yuan. For older vehicles, pay extra attention to battery voltage - electronic devices will stop working when it drops below 11 volts.
