We all want our vehicles to always be in efficient condition and running smoothly. Break down in the middle of the road, a big NO. 

However, we still see vehicles pulled off on a side road, looking for help. This is where today’s technological advancements and tools like OBD2 are useful.  

These automobile diagnostic scan tools are incredible inventions that have been making waves among car owners, professional mechanics, and DIY enthusiasts. 

Whether you own a personal vehicle or run an auto repair shop, having a diagnostic scan tool for Australian cars ensures you can quickly identify and fix issues before they turn into costly repairs.

So, why do you really need the OBD2 diagnostic scan tool? Well, there are many benefits, and we will talk about them in this article. 

Why Buy an OBD2 Scanner?

On-board Diagnostic 2 (OBD2) scanners are automotive diagnostic tools for diagnosing and troubleshooting problems with a vehicle's engine and other components. More specifically, OBD2 scanners: 

• Diagnose Engine Problems

When the "Check Engine" light illuminates, an OBD2 scanner is used to read the codes stored in the engine control module (ECM) or powertrain control module (PCM) to identify the cause of the problem.

• Monitor Emissions

OBD2 scanners can also check a vehicle's emissions system. This is significant since many jurisdictions require you to register your vehicle in order to pass an emissions test.

• Reset Fault Codes

After you've resolved the problem, an OBD2 scanner can clear the fault codes stored in the ECM or PCM. This will disable the "Check Engine" light and enable the car to pass an emissions test.

• Improve fuel efficiency

OBD2 scanners may also track data on a vehicle's fuel efficiency, such as the air/fuel ratio, engine speed, and throttle position. This data can be used to identify problems that may be affecting the vehicle's fuel efficiency.

OBD2 scanners are crucial equipment for both mechanics and vehicle owners. They provide information about a vehicle's health and can assist in preventing future repairs, saving you both time and money.  

• Portability

Many drivers observe check engine lights while driving. Nothing ruins a road trip like a broken-down car.

Because they are relatively tiny, owners may easily transport code readers. Then, if your check engine light comes on, you won't have to worry about finding a reliable repair facility to do diagnostics.

Code scanners provide peace of mind in a portable package. 

• Increase the Likelihood of a DIY Fix

Identifying the source of your vehicle's malfunction increases your chances of being able to fix it yourself. Certain code scanners provide more information than others. However, because the information from various systems is consistent across vehicles, you can utilise Google and YouTube to learn more about your individual codes.

Has your car been running rough or sounding strange? To restrict your search results, combine any symptoms you've noticed with the codes you've entered.  

Does Your Engine Need to be Running to Use an OBD2 Scanner?

This is a widespread myth; however, using an OBD2 scanner car diagnostic tool does not require that your car be running. Yes, you heard that correctly! 

In fact, it is usually safer to turn off the engine before connecting the scanner to minimise electrical problems. When you attach your scanner, your car's battery will supply the power it requires to perform diagnostics.

However, certain tests require the engine to be turned on or in "Accessories" mode. These include real-time data readings and checks on components like the oxygen sensor. This is because the components must be activated in order for the OBD2 scanner to collect accurate data. 

So, certainly, your car does not always have to be operating. But, no, it is not a blanket rule. Does this sound chaotic? So, that's vehicles for you. Isn't it a perfect balance of chaos and precision, a symbiotic dance of complexity and simplicity?

What OBD Scan Tool Should You Choose?

Choosing an OBD vehicle diagnostic tool is partially determined by your level of familiarity with vehicles. If you're the type of person who rolls up your sleeves and changes your oil on a regular basis, you'll probably prefer something with a few extra features. 

You wouldn't consider Googling engine codes or seeking definitions for such codes if you knew what the reading for your car's oxygen sensor or EVAP system should be.

Furthermore, if you're very handy, you'll obviously be pleased if you discover a code indicating a loose gas cap or another relatively small problem you can repair and clear yourself. 

Consider how much money you'll save by not going to a mechanic's shop for that diagnosis and repair. 

However, simply knowing what code caused the "Check Engine" light is not a complete diagnostic. Any OBD scanner (automotive diagnostic computer) is only a starting point for further testing, not the end of the journey. 

Furthermore, while a code may indicate which circuit malfunctioned, it does not explain why. A code does not, on its own, reveal the complete nature of the problem.

Conclusion

An automobile diagnostic machine like an OBD2 scanner is an essential tool for both car owners and mechanics, providing real-time insights into vehicle health. Whether you need to diagnose engine issues, monitor emissions, or reset fault codes, investing in car diagnostic tools can save time and money while ensuring your vehicle runs efficiently.
