In the world of automobiles, one thing is for certain, seeing any light pop up on your dashboard warrants a genuine concern. When you can identify that it’s the check engine light, your concern is even greater. The check engine light or malfunction indicator lamp (MIL) is one of many warning lights on the dashboard of your vehicle that will illuminate to notify you when there is an issue that needs your immediate attention. Learning how to decode the check engine light is important for any car/truck owner, despite the anxiety it may cause.
Today’s article will provide guidance on understanding the world of car/truck scanners and Bluetooth bidirectional scan tools. We will equip you with the knowledge and tools necessary to decode the check engine light and reveal and prevent potential issues.
Understanding the Check Engine Light
When your vehicle's check engine light comes on, it means that the onboard diagnostic system has detected a problem with your engine, emissions control system, or transmission. It's important to seek help and have the reason for the check engine light reviewed before diagnosing it as an engine malfunction as the causes can be varied and even as simple as a loose gas cap. Getting professional observation is crucial in this case.
A check engine light appearance should take your memory to your last fluid (oil and transmission) level checks. When these fluids run low, you place the engine health of your car/truck in danger. Tardiness in fluid checks and requisite vehicular servicing could cost you a new engine or other costly repairs that can be avoided. Air filters and fuel filters are also critical to the health of your engine and overall vehicle. A failed engine can also cause you to meet in an accident.
Ignoring a check engine light is never wise and it becomes even more dangerous in the presence of smoke coming from the engine, obvious engine noises, diminished fluids, and rough idling.

Tools Needed for Scanning
Having now deciphered just how critical it is to understand check engine light and why it should never be ignored, let's dive into the tools needed to perform extensive scanning.
The On-Board Diagnostics II (OBD-II)
Let's start with the OBD2 scanner, what it is, and why it’s essential. The OBD-II scanner is a tool used specifically for scanning and diagnosing issues with vehicles since 1996. It is plugged directly into the OBD-II port, typically located under the dashboard of your car/truck, and intelligently interacts with the onboard computer system.
OBD-II scanners are universal and user-friendly. They work well with the majority of vehicles regardless of manufacturer. Mechanics can easily work their way around interpreting effectively and accurately. The scan it provides is quite comprehensive as it can retrieve Diagnostic Trouble Codes (DTCs) within the vehicle’s computer system. This check shows the specific issue that caused the check engine light. Advanced OBD-II scanners are known to provide data analysis for other engine-related matters.
For persons interested in using an OBD2 scanner, it is cost-effective and easy to maneuver even at home without the professional supervision of a mechanic. However, depending on the nature of the data found concerning the issue of your car/truck, you might need professional assistance in fixing your engine-related matters.
Smartphone Apps as an Alternative
The other tool that can be used for scanning your car/truck is a smartphone app. Like traditional OBD2 scanners, smartphone apps are also cost-effective (often free or way cheaper than an OBD-II scanner) and an efficient solution. These DIY app options work by optimizing bluetooth or wifi adapters to connect to the vehicle’s onboard computer system. This then allows the smartphone app to provide diagnostic information directly to your smart device. Smartphone apps are also portable and convenient seeing as they are located on your smartphone or smart device.

Bluetooth Bidirectional Scan Tool
Professional mechanics tend to gravitate to using bluetooth bidirectional scan tools. It is the tool of choice because of its advanced abilities. One of the features of the bluetooth bidirectional scan tool that makes it superior to the traditional OBD-II scanners is that bidirectional scan tools not only retrieve diagnostic information from the vehicle’s computer system but also send commands to provide testing, actuating solenoids, activating relays, and commanding component tests. The Bluetooth bidirectional scan tools are rather comprehensive covering matters concerning the engine, transmission, ABS, airbag, and more. Thus, making it the top contender among scan tools especially as it relates to complex issues.
With the Bluetooth bidirectional scan tools, you can also look forward to advanced construction and diagnostic algorithms, and regular software updates to ensure accurate and reliable overall performance. Lastly, it even pairs with smartphones/devices/tablets via Bluetooth thus giving you advanced and smart apps functioning in one device. Therefore, diagnostic information and control vehicle systems are available from your mobile device with the bluetooth bidirectional scan tool.
