Auto Service Technician is a skill standardized by National Skill Development Corporation India. This is Participant Handbook Part I.
Job of Auto Service Technician:
Automotive Service Technicians inspect, repair, and maintain automobiles and other gasoline, diesel, or alternate-fueled vehicles. In smaller shops, Technicians complete a wide variety of repairs from simple engine tune-ups to tearing down, repairing, and rebuilding of complete power systems.
They also service and repair electrical systems; align and service suspension, braking, and steering systems; repair and service air conditioning, heating, and engine-cooling systems. In larger shops, some of this work is completed by specially-trained Technicians who are assigned by their specialty area, such as brake repairers, undercar or transmission mechanics.
To diagnose an automotive malfunction, Technicians may need to test drive a vehicle or use a variety of testing equipment, such as onboard and hand-held diagnostic computers or compression gauges to identify the source of the problem. These tests indicate whether a part is salvageable or whether a new part is needed to repair the vehicle.
Today’s automobiles are run by complex computers and integrated electronic systems. The work of Automotive Service Technicians has progressed from mechanical repair into a high-technology job. The advances in automotive technology create a need for workers who can use computerized shop equipment and work with electronic components while maintaining their skills with traditional hand tools.
Automotive Air-Conditioning Repairers install and repair air-conditioners and service their components, such as compressors, condensers, and controls. They complete special training concerning the handling and disposal of refrigerants to comply with federal and State regulations.
Brake Repairers adjust brakes, replace brake linings and pads, and make other repairs on brake systems. They also diagnose and repair computer controlled anti-lock brake systems and traction control.
Undercar Specialists align and balance wheels and repair steering mechanisms and suspension systems.
Transmission Technicians work on gear trains, couplings, hydraulic pumps, and other parts of transmissions. Transmissions are very complex components that involve some of the most sophisticated technology used in vehicles.
Engine Performance Technicians service emission control systems and adjust valves or replace spark plugs and other parts to ensure efficient engine performance and the proper operation of emission control systems.
