What Causes Power Leakage in Haval H6?
3 Answers
Haval H6 power leakage can be caused by electrical consumption, battery issues, wiring or component problems, etc. Below are the specific reasons for power leakage: Electrical Consumption: Failure to turn off vehicle electrical devices when parked leads to battery drain. Battery Issues: Short circuits or oxidation shedding of battery plates cause self-discharge and battery drain. Wiring or Component Problems: This is usually due to grounding issues caused by vehicle electrical devices, wiring harnesses, actuators, sensors, and other electronic components and circuits. Aftermarket Equipment:
My Haval H6 once had a power leakage issue, which made it impossible to start the car in the morning, and it was particularly frustrating. The main reasons might be that the battery was too old, with performance declining after years of use, especially worse in winter; or there were electrical devices left on inside the car, such as an unplugged car charger socket, consuming power over time; it could also be a problem with the alternator, failing to charge the battery, leading to gradual power loss. The Haval H6's electronic modules sometimes have bugs, and the body control unit might secretly consume power, along with aftermarket additions like dash cams or extra lights, which are more likely to cause short circuits. I recommend first checking the battery's health status and unplugging unnecessary electrical devices. If the problem persists, it's best to visit a professional repair shop to test the circuit, to avoid regretting it when safety is compromised.
In maintenance experience, the Haval H6's power leakage is commonly caused by battery aging or alternator failure, leading to charging issues; or circuit short circuits, such as wiring harness wear or poor contact, resulting in excessive background current; the vehicle's control modules, like the BCM (Body Control Module), if the software isn't updated, may malfunction causing continuous power drain; external devices, such as USB ports or audio modifications, are more likely to trigger problems. It's recommended that owners use a multimeter to measure the dormant current, identify the source, and replace critical components in time to avoid greater losses. Paying attention to these points during regular maintenance can save trouble and effort.
