Auto Diagrams
Do you have questions? Ever wondered how the brakes system works, or what fuel injection is all about? We've got answers. Click on the topics below for an in-depth diagram that shows you how it works and offers meaningful maintenance tips to help you take better care of your car.
ABS Brakes & Conventional Brakes ~ Ever wondered what the difference between ABS and Conventional Brakes is? Click here to find out.
Charging System ~ The charging system on late model vehicles has demands far in excess of those required by older vehicles. Increased electrical demand through use of electrically operated components, decreased battery size (due to downsized vehicles and weight reduction) and close voltage regulation (required for reliable computer operation) have all impacted the charging system. Learn more.
Cooling System ~ Most late model cars use electrically driven cooling fans to replace the older mechanically driven fan. Learn about two of the underlying reasons here: 1. To eliminate the parasitic draft of the fan when not needed. This maximizes fuel efficiency and minimizes exhaust emissions. 2. To accommodate transverse engine mounting (front wheel drive).

Emissions ~ In addition to its duties with respect to fuel, ignition, cooling, charging and A/C functions, the computer system also monitors and controls a variety of emissions-related functions and components.

Exhaust System ~ Even the simple exhaust system has not escaped control by the automotive computer. In addition to performing its traditional functions of directing hazardous gases safely away from the vehicle's occupants and reducing exhaust noises to acceptable levels, it has become a primary component in reducing automotive emissions.
Fuel Systems ~ Controlling the fuel injection system on a late model car is one of the primary functions of the computer system. Learn more here.
Heating, Ventilation, & A/C System ~ The heating, ventilation and air conditioning system is controlled by the computer system. This system operates on the basis of receiving information from the sensors in various locations (INPUTS). When those conditions match the preprogram circumstances, the computer causes certain actuators to adjust accordingly (OUTPUTS).
Ignition ~ Ignition system operating and timing control on late model cars are accomplished by the engine control computer. Various vehicle and engine operating conditions, including which cylinder is approaching power stroke and exactly where the crankshaft is in it rotation, are monitored by sensors which send their signals to the computer.
