If the fault light of the type2 charging cableis on, it may be caused by many factors. Here are a few. If the fault light is on during use, you can refer to the solution.

1. A common reason is that the household power socket is not grounded. Since the charging pile of the car usually has a grounding detection function for safety, if the socket is not grounded or the grounding is not reliable, the charging cable may not work properly, causing the fault light to light up.

2. Damage to the charging cable itself may also cause the fault light to light up. For example, the components inside the type2 charging cable may fall off or break, or the plug may be deformed, the line may be short-circuited, and other problems may affect the normal operation of the charging cable.

3. If the voltage of the generator is lower than the battery when the car is driving or under light, the generator cannot work, or there is a problem with the power line, it may also cause the fault light of the charging cable to light up. In this case, the car is in a power state, and the generator and charger should be repaired as soon as possible.

In summary, when the type2 charging cable fault light is on, we should first check whether the socket is grounded, then check whether the charging cable itself is damaged, and whether the car's power line is normal. If the problem persists, it is recommended to contact a professional maintenance personnel for inspection and repair to ensure the normal operation of the charging system.
