ECM PCM in Automotive Computer System Operation

Nowadays, many auto manufacturers install an engine computer system to their units which refers to Engine Control Module (ECM) or Powertrain Control Module (PCM). This module generates many kinds of input sensors and switches for information. They operate various components, including voltage regulators, A-to-D converters, output drivers (Transistors), and pressure sensors. When having issues, these components need to be repaired using the latest and advanced tools such as the best transistor tester to test if something is wrong with the output drivers.

Computer System Operation in an

There are three zones in computer systems, which are input, processing, and output. The input to the computer revolves around switches and sensors. Processing is done inside the personal computer. The computer system works exclusively with voltages. Most sensors convert a voltage signal, usually 5 volts, to a voltage between 0 and 5 volts.

Some detectors send an analog voltage to the computer, so it is a constant or variable voltage, while other sensors send a digital DC signal, which can be an on/off or a large low signal. When a technician connects a scanning instrument or computer to the machine, it will read temperatures in levels, PSI pressures, and positions in ratios. The computer interpreted these readings. The computer links the detector data with an algorithm plus other information and includes an answer for whatever needs to be done to get the machine running.

Voltage Regulators

The computer runs at a lower voltage than the rest of the vehicle. At the beginning of this report, we talked about VREF of 5 volts. This voltage must be fairly accurate and safe. Otherwise, the detector readings would not be accurate. If the voltage regulators are wrong for some reason, you can have error codes for many detectors because the detector voltages are off.

A-to-D Converters

An “A-D” converter converts a DC voltage to digital numbers (stimulation) or an AC voltage to a digital DC signal. Computers are DC electronics and don’t know how to do anything else. The A/D converter is like a translator, translating readings that the computer cannot know into something it can use. It is much easier to interpret a digital signal than an analog one. Some signals have a weak voltage and can even be amplified.

Output Drivers

Output drivers refer to transistors generated to maintain power or ground to an injector solenoid, modulator valve solenoid, and many more. Some motor computers have another driver module. Since these output devices generate most of the computer’s heat, some of them use an array of fins or a hot plate to dissipate the heat.

If there is something wrong with the output drivers, the output drivers are sensitive to amperage and can easily burn out if someone uses a bad connection cable or test process. If you have an error code for injector #5 quad, then the motorist for injector #5 is probably burned out. Examine the immunity of the solenoid for injector #5. Low immunity or a short could cause an amperage spike and damage the injector driver.

How to identify good LED lights for cars and trucks

LED lights are a good option for car and truck lighting. There are many benefits that you will get from installing LED lights in your truck. It is true buying LED lights might be a little expensive at the beginning, but you will notice a lot of benefits in the long run. For instance, LED lights are durable than the normal bulbs, and once you buy them, they will last for a long time. The quality of light that is produced by LED lights is also better than the normal lights.

When looking for LED lights, it is important to consider the lifespan. The essence of buying LED lights is for the sake of durability. The more durable the LED lights, the better it is for you. When looking for bulbs, ask the seller about the lifespan. You might be required to pay more for a longer lifespan but this is also worth it. The best-LED lights can go up to 50, 000 hours although most of the lights in the market can go up to 30,000 hours.

Quality of light

You also need to determine the quality of the light that will be produced by the LED lights. The best quality of lighting currently available for LED light bulbs is 6500K light output. With this type of light output, you get a pure white beam that can spread to all corners at night. Always consider LED light bulbs with good quality of light.


It is important to consider LED lights that are waterproof. There are instances when you will be driving on a rainy day, and you want to make sure that your lights are not affected by water. Most of the waterproof LED lights are tightly sealed, and this prevents water from entering inside. You can always tell by looking at the lights closely.

Strong exterior casing

Good LED bulbs should have a strong exterior casing. The best-LED bulbs have aluminum casing and this important in the case of vibrations when off-roading. The exterior casing of the bulb will always determine the lifespan of the bulb because if the exterior is made using a poor material, then the vibrations of the car might damage the LED bulbs.

Tips on selling junk cars

Selling junk cars can be tricky especially if you are doing it for the first time. If you have old cars lying in your compound, it is now possible to get some money from your junk. Where to sell their car is one of the biggest challenges for car junk car owners. You need to find a good seller for your junk cars and get value for your money. Selling your junk cars will free up your compound and give you the space to do many things like landscape. The site of junk cars lying in your compound is not pleasing, and you need to dispose of them as fast as possible.

Selling your junk cars

Proof of ownership

Before you sell your car to a junk car buyer, you need to show evidence of junk carsownership. The car buyer needs to know that the car that you are selling is yours. If you are selling the car on behalf of someone else, you still need to proof ownership and show that you have been given the power to sell the car. Many old cars might not have the title of ownership, but this is still something that is open to debate. The bottom line is the transaction should be as legal as possible.

Check for your belongings

Before you finally hand the car to the car junk buyer, you need to check for your belongings. If you were using the car at some point, then you might have left some important valuables in the car. Check in all the areas of the car just be sure that you did not leave anything behind.

Check for valuables

It is important to check for valuables before you sell your car. There are some items in the car that are likely to be valuable, and they couldn’t be sold with the junk car. Ideally, many junk car companies will buy cars that are not repairable, and this means that they should be complete junks. Valuable items like radios, car batteries and other items should be removed before selling the car.


Remember to remove the plates

In the process of handing over your car to the junk car buyers, you are likely to forget the plates. It is important to remember to remove the plates from your car. The plates are important because you will need to submit them to the motor vehicle department for your registration cancellation. The plates are also used for canceling your car insurance policy.
