Grade 12 - Electrical and Electronic Systems

It is expected that students will:

Have students follow a specified diagnostic procedure (e.g., as provided in a manufacturer's manual) to:
- inspect and test ignition, starting, or charging systems
- record results
- compare the results to manufacturer's specifications.
Have students service or repair appropriate components on the basis of their inspection and testing of the ignition, starting, or charging systems.
Have students diagnose and repair or replace a defective electrical accessory (e.g., power window motor, power antenna, radio, wiper, heater blower motor). Provide teacher direction as they work.
Have students test a sensor using either a scan tool or a DVM, and then replace, if required.

Have students identify the correct procedure and test equipment required to diagnose a particular electrical problem (e.g., no lights, no charging, not starting). Look for evidence that students:
- follow correct procedures
- select correct test equipment
- determine appropriate solution to the problem
- work with care to avoid personal injury and damage to the electrical system.
Have students dismantle and test components of a starter, and re-assemble and bench test the re-assembled starter. Observe to what extent students are able to:
- assess condition of the components of the starter
- determine which components need to be replaced
- successfully complete the task.
Have students identify and test various electronic components, and look for evidence that they are able to:
- locate and identify the various electronic components
- understand the low voltage used in many circuits
- apply the required safe practices when handling and installing electronic components to prevent failure
- identify possible damage caused by jump-starting a vehicle
- identify the number and purpose of computers on certain vehicles
- explain how various sensors can affect engine operation
- understand the use of a diagnostic tool.
