What is the reason for the red light flashing on the dashboard of the Haval H2 after turning off the engine?

The red light flashing on the dashboard of the Haval H2 after turning off the engine indicates that the anti-theft system is active, which is the engine electronic anti-theft system engaging. This is a normal phenomenon. Each key is embedded with an anti-theft transponder. When the key is inserted into the ignition switch lock cylinder and turned to the ON position, the electronic anti-theft ECU communicates with the key via radio frequency. If the key is confirmed to be legitimate, the anti-theft ECU will perform a password verification with the engine ECU. If the password verification is correct, the engine will be allowed to start. The Haval H2 is a compact SUV launched by Great Wall Motors, with a body length, width, and height of 4335mm, 1814mm, and 1695mm respectively, and a wheelbase of 2560mm.
I've encountered this situation with several Haval H2s where a small red dot keeps flashing on the dashboard after turning off the engine. Don't panic, this usually means the anti-theft system is active. I specifically checked the manual—the red light in that position is the engine electronic anti-theft indicator light. Flashing once per second is normal standby mode, just like the indicator light on a home security system. It means the system is guarding your car. However, if it stays constantly lit without turning off, then you should be concerned—it could indicate a faulty anti-theft module or the key chip not being recognized. Last time, when I helped a neighbor check, we found that the issue was caused by wiring interference from an aftermarket dash cam installation. I recommend checking if you've recently installed any electrical modifications. If you're still worried, go ahead and read the trouble codes.
