If you’re a car owner, you probably know that your vehicle has many electronic systems. The most common types include engine control and chassis control. But did you know that there are other important car electronics systems beyond these two? If not, keep reading to learn about some of the lesser-known ones.
Suspension Control Module
The car electronics system suspension control module controls the suspension system. This is important for safety because it works with sensors to control the suspension, which includes dampers and springs. It also controls shock absorbers, which absorb impact during braking or turning corners by compressing fluid inside them and releasing it when you need more traction on slippery surfaces such as snow or ice. The electronic control unit uses these inputs from other parts of your vehicle’s computer system (like its engine management) to determine how fast each wheel should move up or down depending on what’s happening at that moment in time: if there’s too much speed then everything gets stiffer; if there isn’t enough then everything gets softer so that you don’t bottom out when hitting bumps at high speed (or get airborne).
Electronic Control Unit (ECU)
The electronic control unit (ECU) is the main brain of your car. It’s responsible for controlling all the functions, monitoring and controlling all sensors, and controlling actuators. The ECU receives data from various sensors such as temperature sensors or pressure gauges, processes that information, then sends commands to other components such as an air conditioning compressor in order to maintain optimal operation of your vehicle’s systems.
Fuel Pump Relay
The fuel pump relay is a device that switches on and off an electrical circuit to control the flow of electricity through it. The fuel pump relay is located in the engine compartment near the distributor, under the cover of an access panel. The wiring diagram for this system shows how it works with other components like your ignition switch, starter motor, and battery cables.
The testing process involves checking each individual component until you find out which one has failed or needs replacing. To do this you’ll need to use a voltmeter tool that can test amps as well as volts so if yours doesn’t have this option available then try swapping it out for one that does!
Ignition Coil and Spark Plug Harness
The ignition coil and spark plug harness are a part of the car electronics system. It is used to generate a high voltage that flows across an air gap between two electrodes, which produces an electric spark by jumping the gap.
Starter Relay, Power Distribution, Fuse Box
The starter relay is a car electronics system that controls when the engine starts. It has a solenoid coil that receives power from your ignition switch and sends it to the starter motor. When you turn on your key, this relay will close an electrical circuit between its contacts so that electricity can flow through it. This causes an electromagnet inside of your distributor cap to pull in against spring tension until it makes contact with another set of contacts within itself which completes the connection between them (called “making ground”). Once this happens all other systems connected to those two points are activated as well, including lights and computers!
The power distribution box gets its name because it distributes power throughout different areas of your vehicle such as lights or radio systems etcetera. It does this by sending out AC voltage from its alternator through cables called “wires” which are connected directly to each individual component needing access via terminals built into each piece itself (for example speakers).
The Common Car Electronics System
There are many different car electronics systems that you will encounter as a technician. They all perform different functions, but they all have one thing in common: they can be difficult to diagnose and repair when they aren’t working properly.
If you’re just starting out as a technician, these are the common car electronics system components that you’ll want to get familiar with:
- Electronic Control Unit (ECU). The ECU is responsible for monitoring engine performance and adjusting fuel injection timing based on input from sensors such as RPM sensor(s), camshaft position sensors (or distributors ignition), air flow meters/mass air flow sensors (MAF), etc… It can also control various other functions including anti-lock brake systems (ABS) and traction control systems (TCS).
The car electronics system is a very important part of your vehicle. It helps you to keep track of your speed and fuel consumption, as well as other things like tire pressure. This can be very beneficial for those who want to save money on gas or simply want to know how much they have left before needing another fill-up.
