Electronic Diagnostics: What you need to know.

What are Electronic Diagnostics?

An electronic diagnostic is a service provided by mechanics where they use specialised tools to connect to a vehicle's On-Board Diagnostics (OBD) port and retrieve error codes from its internal computer, or Engine Control Unit (ECU). This is done to give the mechanics an accurate pinpointed report of any issues with the engine management, brakes, fuel injection and more without having to take your vehicle apart to identify any faults. This also prevents any further damage to the vehicle and gives an informed basis for repairs.

What it can detect.

Electronic diagnostics can identify problems and provide accurate diagnostics for:

• Engine Management: Ignition coils, throttle performance, fuel injection system, and ignition timing.
• Transmission: Issues with the gearbox.
• Brakes: Health of the braking system, including anti-lock brake (ABS) systems.
• Exhaust System: Quality and potential blockages.
• Sensors: Malfunctions in various sensors and wiring.
• Comfort and Safety Systems: Air-conditioning, park distance control, and Electronic Stability (ESP) systems.

What are the benefits of electronic diagnostics?

Electronic diagnostics can help detect issues with your vehicle early, before they become major, expensive issues. They also provide accurate diagnosis, giving your mechanics a precise starting point for diagnosing faults, ensuring you look in the right place. This allows components to be repaired before they fail, preventing further damage to your car without having to take it apart to identify the problems. Finally, it gives you a clear understanding of the problem, enabling you to make informed decisions about necessary repairs.

FAQs

How long does it take to run a full electronic diagnostics check on a car?

It can take anywhere between 30 minutes to a few hours. Any faults found during the initial test will require more time during the follow-up service.

When should you get electronic diagnostics done on your car?

When it comes to diagnostic checks, once a year is usually plenty, provided that your vehicle is driving okay and has no irregular behaviour.

Does your engine light have to be on to get an electronic diagnostic test?

No, electronic diagnostics review everything in your vehicle, the codes and data, even if your engine light isn't on.

Does an electronic diagnostic test show transmission problems?

Yes, if your vehicle has a transmission issue, a diagnostic test can reveal codes to direct mechanics as to the problem.

Can electronic diagnostics show if your car has a gearbox problem?

Yes, particularly with modern, electronically controlled automatic transmissions, as they can find fault codes that would indicate slipping gears, rough shifting or problems with the control module.
