What you’ll learn
- Get started in the trade: tools, the workspace, taking in a car and talking to the customer
- Measure like a pro: voltage under load, voltage drop on the positive and ground side, current
- Read wiring diagrams and test relays, sensors and actuators
- Test CAN, LIN and K-line buses and look at signals with an oscilloscope
