Fault code B200049 indicating damage to the control unit is caused by an internal software logic failure in the controller. Below is a detailed introduction to automotive fault codes: 1. Meaning: The monitored fault system P represents the powertrain system; B represents the body system; C represents the chassis system; U represents the network or data communication transmission system fault code. 2. The first digit: Indicates whether it is a generic code (applicable to all vehicle manufacturers) or a manufacturer-specific code. For example: 0 refers to a generic code, while 1 refers to a manufacturer-specific code. General Motors in the United States, for instance, has specific numeric type codes to assist in diagnosing vehicle technical conditions. 3. The second digit: Specifies the type of affected fault system, with numbers ranging from 1-7: 1 represents the fuel and air metering system; 2 represents the fuel and air metering system (specifically referring to poor injection system circuit functionality); 3 represents the ignition system or misfire monitoring system; 4 represents the auxiliary emission system; 5 represents the speed control and idle control system; 6 represents the computer output line system; 7 represents the transmission.
