Vehicle diagnosis and maintenance
Vehicle diagnosis and maintenance:
Core areas. This is the original intention behind the birth of the OBD system.
1.1 Reading fault codes: The maintenance technician uses a diagnostic tool to read the fault codes stored in the vehicle ECU through the OBD connector, quickly locating the fault (such as engine, transmission, emission system, ABS, airbag, etc.).
1.2 Clearing fault codes: After repairing the fault, clear the historical fault codes.
1.3 View real-time data stream: Read real-time operating parameters such as engine speed, vehicle speed, coolant temperature, oxygen sensor voltage, fuel correction value, and the status of various sensors and actuators to assist in diagnosing intermittent faults or performance issues.
1.4 Execution of actuator testing: Control the action of certain actuators (such as fuel injectors, idle valves, relays) through diagnostic instrument commands to test their functionality.
1.5 Emission testing: At the vehicle annual inspection or I/M station, the readiness status and fault information related to emissions are read through the OBD interface to determine whether the vehicle emission control system is normal.
