What can an OBD scanner do?

An OBD reader (also called a diagnostic scanner or scan tool) is a vehicle diagnostic device that can be used to read the error memory and data that is recorded on your vehicle systems. Basically, an OBD reader allows you to establish a connection between your car and a mobile app or diagnostic software.

How does a car computer work?

High-level digital outputs – On many modern cars, the ECU (engine computer) fires the spark plugs, opens and closes the fuel injectors and turns the cooling fan on and off. All of these tasks require digital outputs that act like a relay circuit.

Can ECM be repaired?

The first, and easiest, way to repair an ECM is if there’s a problem with the power supply.

This isn’t common.

What happens if ECU fuse is blown?

The voltage or amps surge, causing the ECM 1’s fuse to blow. When the starter fails you will hear a clicking noise or the engine will be hard to start.

How do you know if your car has ECM?

The least invasive way to diagnose your ECM is to connect an onboard diagnostic (OBD or OBD II) tool to the diagnostic port. From there, you can scan to see if your engine computers have produced any error codes. There are many of these codes, and your diagnostic tool’s manual should have information on what they mean.
