Automotive Service Excellence (ASE) A6 Electrical/Electronic SystemsGeneral Electrical/Electronic System DiagnosisEasy
A technician is using service information to troubleshoot an intermittent issue with a vehicle's climate control system. The wiring diagram shows a specific connector labeled 'C205' located in the dashboard harness. The technician needs to physically locate this connector. Which section of the service information would provide the MOST detailed and accurate information for its physical location?
- ADiagnostic Trouble Code (DTC) Charts
- BFuse and Relay Box Layouts
- CComponent Location Diagrams
- DSystem Wiring Diagrams
Show answer & explanationAnswer & explanation
Correct answer: C. Component Location Diagrams
Component Location Diagrams (sometimes called Connector Location Diagrams or Harness Routing Diagrams) are specifically designed to show the physical location of electrical components, sensors, and connectors within the vehicle. They often include exploded views, photographs, or detailed schematics indicating where a connector like 'C205' can be found in relation to other vehicle structures.
Why the other options are wrong
- A. DTC Charts provide diagnostic steps for specific trouble codes but do not contain physical location information for components or connectors.
- B. Fuse and Relay Box Layouts show the location of fuses and relays within specific boxes, not individual harness connectors like C205.
- D. System Wiring Diagrams show the electrical connections and circuits, but typically do not provide detailed physical location information for individual connectors within the harness.
Component Location Diagrams
Component Location Diagrams within service information provide visual and textual guidance for the physical location of electrical components, sensors, and multi-pin connectors on a vehicle.
- Essential for physically locating components identified on wiring diagrams.
- Often include illustrations, photos, and descriptions.
- May be part of 'Electrical' or 'Body' sections of service manual.
