This is a garbled fault code, which requires a specialized decoder or switching to another system to read the correct fault code. Below is relevant information about automotive fault codes: 1. Meaning: Automotive fault codes are codes generated by the vehicle's computer ECU after analyzing a malfunction. Common fault codes are often caused by sensor failures or poor sensor performance. However, some mechanical faults cannot be read by the ECU. The car's dashboard may display some basic fault indications, but these are only a small part. The main method is to use a specialized instrument—a decoder—to read the codes. There are various 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 refer to previously unresolved fault codes, while intermittent fault codes are not fixed.
