Summarize safe handling procedures associated with high voltage A/C compressors and wiring.
Inspect and protect open A/C system components from contaminants during repairs.
Cooling Systems
Check engine cooling and heater system hoses and belts, and remove, inspect and replace fan (both electrical and mechanical), fan sensors, fan pulley, fan clutch, and fan shroud; check operation.
Inspect, test, remove, and replace radiator, pressure cap, coolant system components, and water pump, replace auxiliary oil/fluid coolers, and check oil levels.
Recover, refill, and bleed system with proper coolant and check for leaks and level of protection.
Describe the differences between hybrid and electric cooling systems.
Drive Train
Remove, replace, and adjust shift or clutch linkage, electronic sensors, wires, and connectors.
Remove, replace, and reinstall powertrain assembly, powertrain mounts, drive axle assembly, half shafts, axle constant velocity (CV) joints/driveshafts, and universal joints.
Follow safe handling procedures when handling high voltage powertrain components.
Fuel, Intake, and Exhaust Systems
Inspect, remove, and replace exhaust pipes, mufflers, converters, resonators, tail pipes, and heat shields.
Inspect, remove, and replace fuel and diesel exhaust fluid (DEF) tanks, tank filter, cap, filler hose, pump/sending unit and inertia switch, and inspect and replace fuel lines and hoses.
Inspect, remove, and replace engine components of air intake systems, canister, filter, vent, and purge lines of fuel vapor (EVAP) control systems.
Restraint Systems
Inspect, remove, and replace seat belt and shoulder harness assembly and components, inspect restraint system mounting areas for damage, and repair as needed.
Identify one-time use fasteners used with airbag and seat belt components.
Inspect the operation of the seat belt system.
Conduct pre-scan inspection to verify operation of Supplemental Restraint System (SRS) and use diagnostic trouble codes (DTC) to diagnose and determine repairs.
Inspect, protect, remove, replace, and identify components of the Supplemental Restraint Systems (SRS) sensors and wiring, ensure sensor orientation, and dispose of deployed and undeployed airbag(s) and pretensioners.
Describe the purposes and functions of advanced restraining and occupant classification systems (OCS).
Non-Structural Analysis and Damage Repair (Body Components)
Foundational Standards
Incorporate safety procedures in handling, operating, and maintaining tools and machinery; handling materials; utilizing personal protective equipment; maintaining a safe work area; and handling hazardous materials and forces.
Demonstrate effective workplace and employability skills, including communication, awareness of diversity, positive work ethic, problem-solving, time management, and teamwork.
Explore the range of careers available in the field and investigate their educational requirements, and demonstrate job-seeking skills including resume-writing and interviewing.
Advocate and practice safe, legal, responsible, and ethical use of information and technology tools specific to the industry pathway.
Participate in a Career and Technical Student Organization (CTSO) to increase knowledge and skills and to enhance leadership and teamwork.
Apply literacy, mathematical, and scientific principles and precision measurements when diagnosing problems and making repairs.
Work independently, collaboratively, and in teams to explore concerns, find causes, and take appropriate action by applying principles of STEM.
Safety Precautions
Locate OEM procedures to identify material composition and precautions for the vehicle being repaired.
Examples: mild steel, high strength steel, ultra-high strength steel, aluminum
Identify advanced vehicle system precautions and inspections, including recommended procedures before inspecting or replacing components.
