Course Introduction
Course Description
Welcome to the Wipers & Rain Sensor Diagnostic Online Course
This is Mechanicourse, where you can find automotive practical training courses with advanced diagnostics approach.
In Wipers & Rain Sensor Diagnostic Training course, you’ll gain the knowledge and hands-on skills, required to confidently Inspect, diagnose and calibrate modern windshield wiper and rain sensor systems.
We’ll begin with a comprehensive introduction to wiper and rain sensor technology, covering their purpose, operation, and the different system designs used by various vehicle manufacturers. Understanding how these systems work is the foundation for accurate diagnosis and repair.
Next, we’ll dive deep into wiring diagrams, teaching you how to interpret complex electrical schematics, identify circuits, and trace faults efficiently. You’ll learn a systematic diagnostic approach that can be applied across multiple vehicle brands.
As modern vehicles rely heavily on network communication, the course also explains how CAN-BUS and LIN-BUS networks are integrated into wiper and rain sensor systems.
The course also includes extensive training on the use of scan tools and multimeter. You’ll learn how to use live data and actuation tests on scan tools to find the problem area, and how to preform point to point diagnostic on the circuit to find the exact location of the fault.
In the practical sections, we’ll demonstrate diagnosis on the car and on the real components, we cover testing procedure on several wiper motors, wiper switch, and rain sensor.
One of the highlights of this course is the in-depth analysis of real wiring diagrams and practical diagnostic case studies. You’ll follow step-by-step troubleshooting processes performed on actual vehicles, allowing you to develop the confidence needed to diagnose faults in the workshop environment.
Whether you’re an automotive technician, apprentice, trainer, or enthusiast looking to expand your diagnostic skills, this course provides valuable knowledge that can be applied immediately in the field.
