When the car positioning terminal is in an offline state on the car positioning system platform, relevant professional technicians need to conduct three types of inspections to identify the specific reasons and solve the offline problem.

　　The first type requires on-site hardware troubleshooting, such as whether the GSM antenna is normal, whether the vehicle parking position is normal (the vehicle is in a garage or in an environment without communication signals, which can be checked with a mobile phone from the same operator), whether the power supply is normal (sometimes the power cord may come off), and at this time, the car positioning terminal will display a flashing red light.

　　The second type of situation is that if the first type of situation occurs and cannot be solved after maintenance, the manufacturer needs to conduct a traffic card status search. At the end of the month, there will be a situation where the traffic card of the vehicle positioning terminal stops, and of course, it cannot be ruled out that the traffic card is physically damaged.

　　The third scenario is that if the problem cannot be solved after maintenance in the first and second scenarios, the equipment needs to be completely removed (including the original antenna) and sent to the original factory for hardware and software maintenance, which usually takes about seven working days.
