Do New Energy Vehicles Need OBD Diagnostic Trouble Code Reader?

The original intention of the OBD system is to detect emissions. It's because most vehicles used gasoline or diesel as fuel. Therefore, emission has great significance for vehicle safety. Since the advent of OBDII code reader or OBD scanner, automobile diagnosis has become more and more simple. So, as new energy vehicles become more and more popular, do they still need diagnostic trouble code reader?

Some of the new energy vehicles use hybrid power. Some use alternative fuels. If this part of vehicle occupies a place, then emission testing will continue to exist. Therefore, the diagnostic trouble code reader, as a product for monitoring emissions, will still have market share.

Even the new energy vehicles powered by electricity have retained the OBD system. Because the OBD system is not only for monitoring emissions. It is also a diagnostic system for electrical faults, performance faults and mechanical faults. So even if electric vehicles are the mainstream in the future, they still need to use OBD trouble code reader and other related products to diagnose faults.

Moreover, the function of the OBD diagnostic trouble code reader is not limited to monitoring emissions. It can also read the data stream and display the real-time data of the car. Users can make fault diagnosis more accurate by combining data flow.

In addition, in the process of driving, the driver can know the vehicle condition in time through real-time data. Some diagnostic trouble code readers also provide additional functions such as travel analysis, fuel consumption analysis and various alarms.

Whether in terms of security or cost, OBDii code reader is of great help to users. So, whether it's traditional diesel, gasoline, or new energy vehicles. As long as the OBD on-board diagnostic system is retained, it requires diagnostic trouble code reader and related products.
