What information does a car computer hold?
The information includes vehicle speed, throttle position, airbag deployment times, whether the brakes were applied, if seatbelts were worn, engine speed, steering angles and more. Manufacturers may also have up to 30 additional data points if they want, excluding, they say, GPS location, video and audio.
Where is computer in a car?
This is why when it comes to locating your ECM it’s best to consult your vehicle’s owner’s manual to find the exact location, but typically they are found in the engine compartment, under the passenger floorboard, under the seats, or behind the kick panels.
How do you know if your ECU is bad?
Here are the most common symptoms of a bad ECU:
- Check Engine Light stays on after resetting.
- Car was jump started on reverse polarity.
- Engine turning off for no reason.
- Water Damage or Fire Damage on the ECU.
- Apparent loss of spark.
- Apparent loss of injection pulse or fuel pump.
- Intermittent starting problems.
- Overheating ECU.
Why would you need to communicate with the car’s computer?
Communication among ECUs leads to better performance by your vehicle. When the ECM increases speed, the transmission module knows how to do this while using as little fuel as possible. The Suspension Control Module (SCM) will adjust to provide a more comfortable and safer ride.
How powerful is a car computer?
Hoheisel says Bosch’s onboard AI computer will guide self-driving cars through even complex traffic situations, or ones that are new to the car. “To do so, it will be capable of up to 30 trillion floating-point operations per second – three times as many as a human brain.
How many computers does the average car have?
The average car has 30 to 50 different computers, and high-end cars have as many as 100, and they’re accompanied by 60 to 100 different electronic sensors.
Can I use a laptop in a car?
Is it illegal to use a laptop in a car? No. Except you want do that while driving – that will be breaking quite a number of traffic laws even if you can pull it off.
What is the main computer in a car called?
And just like some futuristic vehicle, the majority of your car’s functions are controlled by its engine computer, also known as its Engine Control Unit (ECU), Engine Control Module (ECM), or Powertrain Control Module (PCM).
What does a laptop in a car mean?
It is in charge of monitoring engine emissions and adjusting the engine to keep emissions as low as possible. The computer receives information from a many different sensors, including: The oxygen sensor. The air pressure sensor.
Can I drive with bad ECM?
If the ECM were to become damaged or faulty, then it could spell trouble for the entire engine because it would not be managed properly. If the engine is not managed properly, then it is not going to operate properly and then your car won’t work properly.
What causes an ECU to fail?
The ECU has seals around it which are supposed to prevent moisture from entering inside. Moisture is a bad thing to have in an ECU because corrosion will form on its components. If the corrosion is not cleaned away quickly, it will cause these components to get damaged. Then you will have a malfunctioning ECU.
Will my car start if the ECU is bad?
If the ECU fails completely, it will leave the vehicle without engine management control, and will not start or run as a result. The engine may still crank, but it will not be able to start without the vital inputs from the computer.
CAN bus in a car?
CAN bus is a set of 2 electrical wires (CAN_Low & CAN_High) in the car network where information can be sent to and from ECUs. The network inside the car that allows ECUs to communicate with each other is called CAN (Controller Area Network).
What diagnostic tools should I buy?

How do computer engines work?
Fundamentally, the engine ECU controls the injection of the fuel and, in petrol engines, the timing of the spark to ignite it. It determines the position of the engine’s internals using a Crankshaft Position Sensor so that the injectors and ignition system are activated at precisely the correct time.
