A technical guide for diagnosing and repairing engine faults in a competition setting, covering safety, diagnostic methods, and component testing.
This document outlines the knowledge and skills required for diagnosing engine faults in a competitive automotive repair scenario. It details diagnostic procedures for three specific engine failure conditions: starter not working, engine not starting, and poor engine performance. It also specifies diagnostic tools, testing methods, and fault setting criteria for competition purposes.
The guide covers technical aspects such as VIN identification, OBD-II diagnostics, sensor and actuator testing, fuel and ignition system diagnostics, and CAN-BUS system analysis. It includes detailed fault setting points for various components and wiring connections, with specific pin numbers and functions provided for reference. This manual is written in Chinese.
Contestants must diagnose and repair three specific faults: the starter motor cannot operate normally and the engine will not start; the starter motor operates normally but the engine will not start; and the engine runs poorly.
The fault is primarily set around terminal control and the anti-theft system not working, specifically in communication aspects.
The faults are mainly set in the control module, power supply, and ground lines, including related control modules, fuses, relays, wiring, and plug connections.
