Auto mechanics of the modern era need extensive computer knowledge to be able to perform many types of repairs that automobiles need. In fact, all cars, trucks, vans and sport utility vehicles use computers to operate tasks from precisely spraying fuel into the engine for burning, shifting the automatic transmissions, performing tasks like regulating the air conditioner, alarm systems and even blow out your airbags in case of an auto accident or collision. The most sophisticated models have an even more sophisticated computer system. These computers perform tasks like a stereo sound system accepting USB, MP3, MP4, Bluetooth, satellite radio, DVD players, and multi-disc CD players. Other computers include body computers, electronic parking, electronic parking brake system, anti-lock, traction control, vehicle stability, suspension, headlamp systems, driver warning system, vehicle warning systems and tire pressure monitor systems. All types of computer systems require special diagnostic procedures and may require special equipment to access the fiber optic data connections as well as the other CAN system connections.
Computer diagnostics can be a science on an automobile. Many factors cause trouble codes and diagnostics are limited to the manufacturer's designs and parameters. Some computer systems allow you to access specific data that may need to be checked to accurately diagnose a problem while other diagnoses require using tools like a lab scope, multi-meter or even a 12 volt test light. Some consumers have a misconception that an auto repair shop or auto dealer have equipment that can fully checkout a car or even a computer for a car. As an example, if a tail light wire is broken in the trunk, a super computer machine can tell you the wire is blue and broken 3 inches from the tail light bulb! This is false, computers on a car are very limited to the information they give, therefore, it takes practical skill to properly diagnose this scenario short. Auto mechanics are the key to a successful diagnose and repair.
Is computer reprogramming on a car possible? Yes, in many cases, computer programming and reprogramming is necessary. From programming a steering sensor to setting up your vehicle theft system, computer reprogramming is a must on all types of auto makes. Special aftermarket equipment can be used, in many cases, to program different computer systems. In some cases, the factory scan tools are the only way to reprogram the computer. Some of the software is available to the auto repair shop via internet or DVD. Other software is built into diagnostic scan tools built to have the necessary programming aspects within the tool. Some reprogramming can be easily performed at a hi-tech local auto repair shop, while some reprogramming is limited to the dealer only.
Hybrid cars are very computerized. From starting the car to driving the car, every second is calculated by several computers to maintain the objective of saving gas. These cars use 2 styles of batteries. One battery controls the vehicle including the computer systems, lights and typical automobile functions. The other battery has high voltage that is used to propel the car with electric power. The charging, starting and driving is computer controlled and regulated. Diagnosing and repairing the hybrid cars is far more complex than the typical vehicle. Many computer systems communicating to operate the hybrid models require a computer skilled mechanic to properly diagnose and repair.
Auto diagnostic scan tools are a must for auto repair shops. Everything from warning lamps to oil change/ service resets require automotive diagnostic scan tools. Scan tools can check specific systems and help the auto mechanic with which way to go for the necessary repair. Some vehicles require a scan tool just to change the brake pads! Computer desktops and laptops can me retrofitted to replicate or become the factory scan tool for the specific car. All of the setting up procedures and diagnostic procedures require a computer savvy auto mechanic with high level of skill and patience. With cars becoming more complicated and incorporating operating systems and hard drives, auto mechanics will have to have major computer skills to be able to keep up with the futuristic cars to come.
