Practical Troubleshooting and Repairs of Automobile Electronics (Vehicles)

1. Training Introduction

Modern vehicles are increasingly reliant on sophisticated electronics for engine management, safety, comfort, and infotainment systems. Effective troubleshooting and repair of automobile electronics require a combination of theoretical knowledge, hands-on skills, and familiarity with diagnostic tools.

This course provides a comprehensive foundation in automotive electronics, covering engine control units (ECUs), sensors, actuators, communication networks (CAN, LIN, FlexRay), and electrical/electronic subsystems. Participants will gain practical experience in diagnosing faults, performing repairs, and restoring vehicle electronic systems to optimal operation.
