Like everything else in life, car diagnostics has also evolved over time. The latest technologies have replaced conventional ways and have become more efficient. Now both technicians and car owners are facilitated with modern equipment and updated software. Auto diagnostics has now eliminated the trial-and-error approach of the repair shop workers and has provided a more accurate way of finding faults in vehicles. The driver is also now well-informed and this prevents unnecessary expenditures.

What is auto diagnostics?

Auto diagnostics refers to the in-built sensors and software systems that automatically detect a problem within the car and generate codes. These codes are then read by particular systems and devices which in turn let the mechanic know the exact issues.

Not only the mechanic but the driver can also study these codes and understand the fault. The auto diagnostic is, in fact, a self-diagnostic system in automobiles that involves constant monitoring of the vehicle’s performance by the vehicle itself and giving out indications in case of any deficiency. This has revolutionized over time and we see various components involved.

How and when are car diagnostic tests performed?

There are two circumstances where car diagnostic tests are performed.

One is when nothing really happens and the tests are seen as preventive measures in order to avoid any complications. They may involve visiting an automobile repair shop or simple home-based tests.

In the other scenario, the car, itself, asks to run diagnostic tests by giving out alerts like ‘check engine light’ and oil indicator on the dashboard. The purpose of preventive diagnostics is to avoid inconvenience and identify the problem before time.

Steps involved in auto diagnostics

• If there are any warning lights, they are analyzed. The method of their analysis is through the diagnostic codes that the vehicle’s computer generates alongside these alerts.
• The code scanner is connected by the technician to the car’s computer system.
• These codes are then scanned into readable formats by the devices connected to the car that help narrow down the problem search. These diagnostic tools are now available in portable, easy-to-operate forms.
• After this drill, the corrective procedure is carried out by the auto repair shops, and the steps are repeated again to check if the trouble codes are still generated or not. Hence clearing the issue.

These are easy steps that automobile owners can perform themselves and then head to their trusted auto repair shop for service.

Warning lights to look out for

Auto diagnostics has helped generate trouble lights that speak for themselves, for example:

• Check engine light pointing to the probable issue with the engine which could be something very simple or complicated like a problem with the exhaust.
• Oil pressure warning light indicates issues like insufficient oil, oil leakage, etc. It should always be followed by a dipstick to check the current oil levels, and if this light persists even after topping the oil, running a complete diagnostic test is always a wise choice.
• Anti-lock braking system (ABS) light could indicate a number of problems like non-functional wheel speed sensors, insufficient brake fluid levels, or faulty brake pad status. This may also mean the car’s inability to activate the ABS system when needed.
• Airbag warning illustrating that something is wrong with one or both airbags. This is a serious issue that will not hinder the smooth running of the vehicle but is sure to be fatal in case of an accident.
• Then there are alerts like fuel lights, pressure monitoring system lights, door open lights, etc.

These are just a few examples of the many features now available in modern cars and are leading points in car diagnostics. Once the interventions are performed, these warning signs must disappear indicating the correct resolution of the issue.

How long does the diagnostic procedure take?

Running a diagnostic test is a matter of a few minutes; however, it’s just the first step. It is feasible to buy some equipment and carry this out within the comfort of one’s home. The process of repair follows. The latest cars are equipped with OBD (On-board diagnostic) systems which help the vehicle’s auto diagnostic capability and catch any troubles present in the engine and brakes etc.

Benefits of auto diagnostics

There are multiple benefits of auto diagnostics:

It is time-saving: It saves time in two ways. One is by diagnosing the problem way before it complicates, thus providing easy solutions. The other is by narrowing down the art of troubleshooting. There is no beating around the bush and the technician can quickly come to a conclusion regarding the issues with the vehicle.

It is economical: If the issues are taken care of before they escalate, the expenditure is limited too. Timely action prevents excessive damage.

It saves lives: Identifying certain problems can be lifesaving. Auto diagnostics saves lives by giving away warnings about certain things that might otherwise be ignored, for example letting the passenger know about the issues with brakes or airbags.

It empowers the driver and the technician: Auto diagnostics not only empowers the auto repair technicians but car owners too. With its easy-to-handle system; the driver can become conversant with the issue at hand thus minimizing the risk of getting scammed by technicians.

Auto diagnostics have revolutionized car diagnostic tests. It has made vehicle maintenance easier and has contributed to the longevity of automobiles.
