    5. Test and confirm operation of electrical/electronic circuits not displayed on diagnostic tools.
    6. Diagnose concerns resulting from failures of interrelated systems (for example: safety, cruise control, security theft deterrent, transmission, electronic stability control, auxiliary power units (APU), and non-OEM installed accessories).
    7. Measure and interpret voltage, voltage drop, amperage, duty cycle, frequency, capacitance, and resistance readings using a digital multimeter (DMM) or appropriate test equipment.
    8. Check, test, repair, and/or replace electrical connectors, pins, harnesses, seals, and locks.
    9. Troubleshoot failures in the data communications bus networks; and determine needed actions.
  3. Explain the various air-induction systems, and perform proper test procedures.
