What is a Computer Diagnostic and repair service?
You’ve seen the lights on your dashboard: Check Engine… or maybe just an outline of an engine or transmission. This means you need a computer diagnosis service which is a general analysis of the current state of the vehicle’s systems. This is the first step to verify elements that are not working properly.
Vehicles in the previous 10-15 years have become extraordinarily intricate machines and for most people, the days of the shade tree mechanic, fixing the vehicle at home on a Saturday afternoon are long gone. Vehicles today (like many other products in our lives) are equipped with onboard computers that constantly monitor their performance and can actually make undetected adjustments to the vehicle as you happily drive down the road.
The computer in your vehicle, also known as PCM, is in charge of monitoring engine gases and adjusting them accordingly to keep emissions as low as possible, it contains sensors for:
- Air pressure.
- Air temperature.
- Engine temperature.
- Throttle position.
- Pre-ignition or detonation.
- Functions of the computer
- Control the power train: ignition system, fuel injection system, and emission control.
- Control the transmission.
- Regulate the voltage of the charging system.
- Set and control the on/off cycles of the electric fan.
- Reduce power by interacting with the ABS system when traction control is present.
- Interact with the automatic temperature control system to operate the operating cycle of the air conditioning compressor and some safety functions.
- Generate an alert through the check engine light on the vehicle’s dashboard and set a fault code, which will be easy to read and analyze later through the use of diagnostic equipment or an automotive scanner.
So, what to do if your Check Engine light comes on?
These are warning lights to indicate that there is a problem with the computer controls for that system or device. When the light starts flashing, it indicates that the computer has identified a problem in the vehicle’s system.
It is very important that these signals can be checked on time, many people underestimate the lights on and assume it is a problem with the sensor and does not go to a check-up in time.
