How to Know if You Need a Car Diagnostics

Wondering if your car needs a diagnostic test? 

Here are some telltale signs that indicate it might be time to seek car diagnostics:

Warning Lights

If your dashboard is adorned with persistent warning lights, such as the check engine light, ABS light, or any other malfunction indicator, it's a clear indication that something requires attention. Diagnostic testing can help identify the specific issue triggering these warnings and guide you toward the necessary repairs.

Performance Issues

Notice a decline in your car's performance? Whether it's a decrease in power, rough idling, difficulty starting, or a noticeable drop in fuel efficiency, these performance issues may be symptoms of underlying problems. Diagnostic testing can pinpoint the root cause and provide insights for resolving the issues effectively.

Strange Noises

Unusual noises coming from your car, such as grinding, rattling, squealing, or knocking, should never be ignored. These noises can indicate problems with various components, including the engine, transmission, brakes, or suspension. A diagnostic test can help identify the source of the noise and determine the appropriate course of action.

Electrical Problems

Are your lights flickering, your windows not functioning correctly, or your car experiencing intermittent electrical issues? 

Electrical problems can stem from wiring issues, faulty sensors, or other electrical components. A diagnostic test can help diagnose and resolve these problems, restoring the proper functioning of your car's electrical system.

Emissions Failures

If your car fails an emissions test or you notice excessive smoke or unusual odors from the exhaust, it's essential to investigate further.

A diagnostic test can help identify the source of the emission issues, such as a malfunctioning sensor or a faulty catalytic converter, and enable you to take the necessary steps to rectify the situation.

Unexpected System Malfunctions

Any unexpected or recurring malfunctions in your car's systems, such as the air conditioning, power steering, or braking systems, should be examined through diagnostics. These malfunctions can be indicative of sensor failures, fluid leaks, or other mechanical or electrical issues that require attention.

Regular Maintenance Schedule

Lastly, even if you don't notice any specific problems, it's still beneficial to include regular diagnostic testing as part of your car's maintenance routine. Diagnostic tests can help identify minor issues before they escalate into major problems, potentially saving you from costly repairs and unexpected breakdowns.

What Does a Car Diagnostics Include

A car diagnostic test involves connecting specialized diagnostic equipment to your vehicle's onboard computer system, also known as the Onboard Diagnostics (OBD) system. 

This test provides valuable information about your car's performance, identifies any existing or potential issues, and helps in troubleshooting and resolving problems.

Here's what car diagnostics typically includes:

Scanning for Trouble Codes

The diagnostic equipment scans the OBD system to retrieve any stored trouble codes. These codes provide specific information about the area or component of the vehicle experiencing a problem. Each code corresponds to a particular issue, such as an engine misfire, oxygen sensor malfunction, or transmission problem.

Live Data Stream

The diagnostic tool can display live data from various sensors and modules in your car. This includes parameters such as engine RPM, coolant temperature, fuel system status, oxygen sensor readings, and more. 

Analyzing this data can help identify anomalies, irregularities, or out-of-spec values that might be affecting your car's performance.

Component Testing

Some diagnostic tools offer the capability to perform component tests. These tests assess the functionality of specific parts, such as fuel injectors, ignition coils, or sensors. By activating or monitoring these components, the diagnostics can determine if they are operating correctly or require further inspection.

Resetting and Clearing Codes

Once the trouble codes have been identified and analyzed, the diagnostic tool can often reset or clear the codes from the vehicle's memory. This allows you to see if the issues were temporary or if they reoccur after the reset. 

However, it's important to note that clearing codes without addressing the underlying problem may result in the codes reappearing.

Accessing Manufacturer-specific Data

Advanced diagnostic tools may have access to manufacturer-specific data, enabling deeper insights into your car's systems and providing more detailed diagnostics. This information can be especially helpful when dealing with complex or proprietary systems in specific car makes and models.

Interpretation and Reporting

The diagnostic tool interprets the retrieved data and presents it in a clear and concise format, allowing the technician to understand the diagnostic results. The tool may provide suggested actions or recommendations based on the identified issues.

Additional Inspections

While the diagnostic test primarily focuses on the electronic systems, it can also guide the technician to perform further inspections or tests on mechanical components, wiring, or other areas of concern as identified during the diagnostic process.


Comprehensive diagnostics reveal the hidden answers beneath the hood of your vehicle. 

From mysterious warning lights to mysterious engine issues, specialized diagnostic testing can provide valuable insights into your car's condition and enable you to make more informed decisions about repairs or maintenance.
