What does code on a car mean?

[LilahMarie]

Car code indicates that there is a fault in the vehicle, and the specific fault code needs to be checked by connecting to diagnostic equipment. Below is relevant information: 1. Different functions depending on the vehicle model configuration: Some vehicle models' driver information centers cannot display Chinese messages, and vehicle information will show faults as code numbers. For example, Chevrolet Cavalier code 35 means "Please replace the remote key battery," and code 79 means "Insufficient engine oil, please add." 2. Serves to check mechanical faults: Some fault codes may not necessarily indicate electronic component failure but could also be caused by mechanical issues. Mechanical problems can lead to distorted signals in the electronic control system, generating fault codes.
