Where is the problem when EV function is restricted?
1 Answers
EV function restriction is caused by a faulty high-voltage system. The following is a relevant introduction about automotive fault codes: 1. Meaning: Automotive fault codes are error codes reflected by the vehicle's computer ECU after a malfunction occurs. Common fault codes are usually caused by sensor failures or poor sensor performance. However, some mechanical faults cannot be detected by the ECU. The vehicle dashboard may display some basic faults, but that is only a small part. The main diagnosis still requires the use of specialized equipment—a decoder. There are many types of decoders, such as X-431 and KT300, but their working principles and the fault codes they read are the same. 2. Classification: Fault codes are divided into real codes, historical codes, and intermittent codes. Real codes are easy to detect, historical codes, as the name implies, are unresolved fault codes left from previous issues, while intermittent fault codes are not fixed.
