How To Fix Malfunction Indicator Lamp
What to do when the Malfunction Indicator Light is on?
People are often interested in Vehicle Diagnostics when the Problem Indicator Light is on on the dashboard of their car. The Malfunction Indicator Light (MIL) is also known as the Check Engine Light. The purpose of this warning light is to indicate a detected problem with the vehicle and alert the driver of the problem. Lights come on for a reason only and you shouldn’t ignore it. You should always investigate the cause. Read: how to troubleshoot indicator lights
What does the Malfunction light mean?
The Fault indicator can signal three different types of problems.
- Sometimes flashing indicates a temporary engine malfunction. In this case, it is best to be aware of possible problems coming up which could later turn to more serious problems.

- The most severe type of signaling is when the MIL flashes all the time. It’s a sign that your car’s engine is misbehaving. The problem is a big one and you should stop the engine immediately to prevent serious damage. For example, it can cause the catalytic converter to overheat and even cause a fire.
NB It is completely normal if the light stays on for a few seconds when you start the engine. But it will turn off when the engine is running.
How to get more information about this issue?
Some OBD-II problems are relatively minor. Those things don’t have much effect on engine performance. On the other hand, some problems are big and need to be dealt with appropriately. Unfortunately, there is no way to distinguish between them by just looking at the MIL. The included tool and software can read the Diagnostic trouble code(s) from the system. Every time the OBD system turns on the MIL, it also stores the Diagnostic Trouble Code (DTC) in the electronic control unit. The DTC will provide information about the detected problem. The OBD2 system can automatically turn off the MIL if the conditions for a stop failure exist. After evaluating a system or component three times in a row without detecting a problem, the light can be turned off. However, normally the light stays on. What are the next steps? If you have an OBD-II lens (for example, a lens with an ELM327) chip and OBD diagnostic software, you can check the reason for the problem yourself. For example, our car diagnostic software can read a DTC code from a car and give you a description of the code. Those will guide you to the main cause of the problem. With diagnostic software, you can even manually reset the MIL. It is important to clear the Problem Indicator Light after troubleshooting. This is because, for example, the vehicle will fail the emissions test if the MIL light is ON during the test. : how to use comb on top of natural hair
