Answer :

Final answer:

This task involves diagnosing three electrical issues in a selected motor vehicle, including headlights, wiper motors, and indicators. You should research and document these issues alongside their solutions, including current flow diagrams and manufacturer reports. The structured approach facilitates clear identification and resolution of the electrical faults.


Explanation:

Task Overview

This practical application task focuses on diagnosing and repairing electrical faults in a motor vehicle. You are required to choose a recent vehicle model and identify three electrical problems that commonly occur within its systems.

Step-by-Step Guide

  1. Choose a Vehicle: Select any modern make and model, such as a 2022 Toyota Camry, known for its electrical features like headlights, wiper motors, and indicators.
  2. Identify Electrical Problems: Research common electrical faults experienced in your chosen vehicle. For example:
  • Headlight failure – where either the bright or dim lights do not function correctly.
  • Wiper motor malfunction – which may cause intermittent or no wiper function.
  • Indicator failure – where turn signals do not illuminate or blink at the correct rate.
Current Flow Diagrams: Search and print current flow diagrams for the selected systems. For instance, a diagram detailing headlight wiring connectivity.Manufacturer Reports: Gather the manufacturer report for the chosen model, which may include electrical specifications and common issues.Documentation Preparation: Ensure all printed documents (flow diagrams and reports) have watermarks, as these will be part of your submission.

Solutions and Reporting

For the identified problems, conduct further research on solutions:

  1. Headlights: Solutions could include checking the relay, fuses, and replacing bulbs.
  2. Wiper Motors: This may involve checking for faulty connections, replacing the motor, or addressing issues with the switch.
  3. Indicators: Solutions might involve inspecting flasher units, bulb replacements, or wiring checks.

Finally, compile a report summarizing your findings, the vehicle’s model, year, make, and the identified solutions.
