The earliest electronic systems available as factory installations were vacuum tube car radios, starting in the early 1930s.The development of semiconductors after World War II greatly expanded the use of electronics in automobiles, with solid-state diodes making the automotive alternator the standard after about 1960, and the first transistorized ignition systems appearing in 1963.
Automobile electrical circuit breaker with resettable switch. Automotive fuses are a class of fuses used to protect the wiring and electrical equipment for vehicles. They are generally rated for circuits no higher than 32 volts direct current, but some types are rated for 42-volt electrical systems. They are occasionally used in non-automotive ...
A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM).

An ECU from a Geo Storm. An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
Some benefits of an automotive TSB are that by widely circulating among dealership service departments and mechanics an engineering-level description and solution for a problem common to type, year, make or model of car, a well-managed TSB process can save technicians troubleshooting time; provide organized, itemized repair procedures; and ...
Some have electrical connectors, and others have optical fiber connectors. A breakout box serves as a troubleshooting tool to determine the wiring of an electrical connector interface on a networking device or computer. Typically, a breakout box is inserted between two electrical devices to determine which signal or power interconnects are active.
Vehicle breakdowns have various causes. Depending on the severity, the vehicle may need to be towed to an automobile repair shop or fixed on-site by roadside assistance or a mobile mechanic. With other problems, the driver may be able to operate the vehicle seemingly normally for some time, but the vehicle will need an eventual repair.
A motor vehicle service or tune-up is a series of maintenance procedures carried out at a set time interval or after the vehicle has traveled a certain distance. The service intervals are specified by the vehicle manufacturer in a service schedule and some modern cars display the due date for the next service electronically on the instrument panel.
