Most of us panic when our car show us a check engine light or a fault code(if you have a reader). But do we really know what they are all about or do we just ignore it? Let us explain to you what fault codes really mean!

Fault codes are stored on the on-board computer diagnostic system (OBD-II). OBD-II is connected to the Electronic Control Unit (ECU), which can read the vehicles fault codes. Fault codes can tell you exactly why and where the problem is located causing your check engine light to illuminate.

Always be informed about your car with Carmen! Carmen gives you information about your car’s vital performance stats and alerts you if there’s a problem, before something bad happens. More info at Carmen.sg

Fault codes are typically made of a letter followed by 4 numbers that can specifically tell you what is wrong with your car.

The fourth and fifth characters will refer to the specific component that the ECU has identified the fault in and this is different for each system and sub-system.

But fault codes can be wrongly triggered in some cases by heat or transmission problems that are temporary. Instead by using Carmen, it can clear fault codes, and if the fault code reappears, it means that it is time to take your car to your trusty servicemen. But if it doesn’t, Carmen would have saved you some money and time! Carmen ensures that you are informed on whether your car really is in trouble or not! Find out more at Carmen.sg
