What are the reasons for difficulty in starting a four-wheeled vehicle?

[FinnAnn]

The reason for difficulty in starting a four-wheeled vehicle is under-voltage, because the controller of a four-wheeled electric vehicle has an under-voltage protection function. Methods to detect under-voltage: Check whether the main circuit of the battery is in good contact, check whether the battery is faulty, and check whether the instrument panel is faulty. Four-wheeled electric vehicles require regular maintenance of the battery, charger, and appearance to ensure normal operation. Solutions for difficulty in starting a four-wheeled vehicle: First, disconnect the connectors of each sensor and check their resistance. If the resistance is abnormal, it must be replaced. If it is normal, then check whether the wiring and connectors between the ECU and each sensor are normal.
