What is the reason for the Qin Plus DM-i EV being restricted?

[IsabelleLee]

Qin Plus DM-i EV being restricted refers to a situation where other components on the engine experience functional failure or restricted functionality, prompting the driver to perform timely maintenance. This issue frequently occurs with components such as the generator and compressor. When the vehicle displays an EV function restriction warning, it is essential to immediately take it to a repair shop or 4S dealership for professional servicing. Solution: Restart the vehicle to see if the issue can be resolved. If the problem persists, it indicates that the issue is beyond the capability of an average car owner to fix. To troubleshoot the EV function restriction, it is necessary to connect an OBD scanner to read the fault codes and data stream, identify the exact problem, and then address it accordingly. Precautions regarding EV restriction: It is not advisable to attempt troubleshooting the issue on your own, as BYD's high-voltage electrical system operates at over 700V, posing significant risks. It is likely that BYD manufacturers share this concern, which is why they have implemented a high-voltage interlock protection mechanism.
