WDS
WDS (Wiring Diagram System) is a reference tool that automotive technicians use to understand and repair vehicle electrical systems. It's like having a detailed map of all the electrical connections in a car. Technicians use WDS to find where wires connect, how electrical components work together, and to diagnose problems when something isn't working right. It's especially important for modern vehicles that have complex electronic systems. Think of it as a GPS system, but instead of showing streets, it shows how electricity flows through a vehicle.

Example Interview Questions
Senior Level Questions
Q: How would you approach diagnosing an intermittent electrical problem using WDS?
Expected Answer: A senior technician should explain how they systematically use WDS to trace circuits, check connection points, and test components. They should mention the importance of understanding both the wiring diagrams and the vehicle's history.
Q: How do you train junior technicians to effectively use WDS?
Expected Answer: Should discuss creating a structured approach to reading diagrams, starting with simple circuits and progressing to complex systems. Should mention common mistakes to avoid and practical hands-on training methods.
Mid Level Questions
Q: How do you use WDS to diagnose problems in multiple interconnected systems?
Expected Answer: Should explain how they trace connections between different systems, understand how one system's failure can affect others, and demonstrate knowledge of using WDS to find common connection points.
Q: What's your process for documenting electrical repairs using WDS?
Expected Answer: Should discuss how they record findings, mark updates on diagrams, and communicate changes to other technicians. Should mention importance of keeping accurate repair records.
Junior Level Questions
Q: Can you explain the basic symbols used in WDS?
Expected Answer: Should be able to identify common electrical symbols like grounds, fuses, relays, and switches. Should understand basic circuit flow and component representations.
Q: How do you start troubleshooting an electrical problem using WDS?
Expected Answer: Should explain basic steps of finding the right diagram, identifying related components, and using the diagram to trace the circuit from power source to ground.
