In and of itself, the Check Engine light isn’t helpful. It’s a catch-all light that lets you know there’s a problem– a defective sensing unit can even activate it. You do not know whether the problem is your ignition, transmission, exhausts, electronic devices, and so on. But by using an OBD scanner, you can get to the origin of the problem. When your OBD computer detects a problem, it keeps a five-character code corresponding to that issue. These codes, referred to as OBD or OBD-II codes, are the key to diagnosing your issue. To read your OBD codes, you’ll first need to obtain an OBD scanner, a portable device with a 16-pin plug that attaches to your car. It also has a screen that will visually present any kind of error codes.
Every vehicle built has an onboard diagnostic (OBD) port or diagnostic link connector (DLC). The OBD2 port lies beneath the steering wheel on the driver’s side. It has a 16-pin connector usually covered with a flap or door. Every vehicle built from has an onboard diagnostic (OBD) port or diagnostic link connector (DLC).

If nothing happens, double-check your connection to ensure that the scanner you’re plugged in all the way. If there’s still no activity from the computer, plug something into your car’s cigarette lighter and see if it’s getting power. The cigarette lighter and OBD computer get on the same circuit, so this will let you know if there’s something wrong with the electrical circuit. In that case, you’ll need to change the corresponding fuse.
The check tools are more costly than the code readers but these are equipped to provide more advanced assistance. OBD-II car scanners not only read mistake codes but also help in troubleshooting the problems. Moreover, some of these costs OBD car scanners allow customisation in coding of different elements. OBD-II scanner offers an advantage of resolving most of the problems rather than just supplying codes. You can get more in-depth information on codes in this kind of OBD car scanner.
Diagnosing automobile problems used to be a lot more challenging. A technician needed to utilize every one of their abilities to pinpoint mechanical or electrical issues. Nowadays, TECH 2 Scanner can diagnose numerous problems electronically. With an OBD scanner and a little knowledge, anyone can recognize precisely what’s wrong with their vehicle. What Is An OBD Scanner Modern cars have an onboard diagnostic (OBD) computer connected to different sensors. When one of the sensors detects an issue with your vehicle’s systems, it informs the OBD. The computer then activates your Check Engine light.
Your OBD scanner will have a connection cable with a 16-pin trapezoidal plug at the end. This plug goes into your vehicle’s OBD port, also referred to as the diagnostic link connector (DLC). Different cars will have varied areas for the OBD port. You’ll often locate it underneath the steering wheel, somewhere near the pedals. Less often, it’s located towards the facility of the control panel and even at the passenger side. If you’re having problem finding it, look to your owner’s handbook. Insert your type in the ignition, but do not start the engine. Instead, turn your key only to the point where the car’s power comes on. This will activate the OBD computer, so your scanner can connect with it. Relying on your scanner, you’ll see a visual message letting you know the link is being established.
