Automotive Diagnostics and Vehicle Components – Part 2

car mechanic, auto shop, repair and maintenanceAs discussed in Part 1, automotive diagnostics involve checking several systems in your vehicle. Part 2 will continue by discussing the Ignition System and the Air Conditioning System.

Ignition System & ECU

When the key is turned in the vehicle’s ignition, an electrical charge is sent to the starter motor to crank and start the engine. Afterwards, the ignition system, which is made up of an ignition coil, distributor, distributor cap, rotor, spark plug wires and spark plugs, takes over. An ECU (engine control unit) provides the computerized guidance for the ignition system to ensure optimal engine performance. This system should be inspected as part of the tune-up process.

Air Conditioning System

Typically, the air conditioning (A/C) system of your car should be inspected annually, but check the owner’s manual for your vehicle to confirm the recommended service interval. As time passes, a car’s A/C system gradually becomes less efficient. The main causes may involve defective parts, leaking refrigerant gas, and insufficient pressure.

A/C System Inspection

Inspections of the air conditioning system should include the following three items:

  • Visually check all tubes, pipes, connections, and components.
  • Search for leaks.
  • Check refrigerant gas pressure.

Servicing the air conditioning system of your vehicle will require the removal of the refrigerant gas. Then the pipes, tubes, and connections will be inspected for leaks and necessary repairs are made. Afterwards, the A/C system will be refilled with pressurized refrigerant gas.
