Why can't the differential lock be turned off?

[MollyLynn]

The F1 display on the refrigerator indicates a fault with the freezer evaporator sensor (short circuit or open circuit). The solution to the F1 display is to start the refrigerator after the car is ignited, use an adapter for power supply, and adjust the battery protection to medium or low level. Additional details are as follows: 1. Operating environment temperature of the refrigerator: The higher the ambient temperature, the shorter the battery usage time; 2. Types and quantity of items stored in the refrigerator: The more items, the more power the refrigerator consumes to maintain the set temperature; 3. Frequency of door openings: Frequent opening and closing increases power consumption; 4. Capacity and charge state of the car battery: The larger the battery capacity, the longer the usage time; the more sufficient the charge, the longer the usage time; 5. Set temperature of the refrigerator: The lower the set temperature, the higher the power consumption; 6. Battery protection level setting of the refrigerator: The higher the battery protection level, the shorter the usage time.
