Automobiles have changed significantly over the years and this has made them both more efficient and more complicated. Nowdays, to find out what’s wrong with your car, it’s not as simple as just taking a look under the bonnet. Most modern cars are controlled by advanced engine management systems. The engine computer is called an ECU, and its job is to read and store the fault codes from your car. Not every mechanic can access this information without specialised tools, but workshops that are partnered with industry leaders like Bosch can now offer computerised engine diagnostics.

So why is computerised engine diagnostics so useful, and how they can they save you money and time in the long run?

How Does it Work?

Modern vehicle electronic systems are controlled by a computer that handles multiple systems. From the ignition to the transmission and the fuel injection, there are sensors throughout the car that gather and transmit data back to the main computer modules of the car. This allows for precise control of fuel and ignition so that you get the best performance and fuel efficiency.

The powertrain control module (PCM) manages the whole system. If the test shows up with a signal that is outside the normal limits, then you get a diagnostic trouble code (DTC). Your technician will then scan the system to display any stored codes to see where the problem might lie. It won’t tell you exactly what the problem is, but the scan will show you where there are potential abnormalities so that you can run further electrical or mechanical tests to find a conclusive result.

Fast Information Means Fast Repair

The constant stream of data between different systems in the car makes it much easier for computers to pinpoint any issues within your vehicle. This early detection can reduce the frequency of services and make it easier to fix potentially complex problems.

Understanding the Fault Codes

If your car is running a bit rough or you’ve got a warning light on your dashboard [link to blog 5], a simple diagnostics test could tell us where the problem lies in a hassle-free manner. The computer can give us an in-depth scan of individual vehicle systems for a detailed report on the engine fault codes, which we would be happy to show you. This way, you’ll be able to see exactly what’s wrong with the car much faster than you would have without the computer.
