Figuring out what the code(s) mean?

Modern vehicles have a sophisticated error reporting system, and can have up to a dozen different indicator lights on the dash. It is not uncommon to confuse the check engine light with the service required light. However, these warnings are not necessarily related to one another. The service light typically means the car is due for an oil change or other routine care. The check engine light, on the other hand, is an indicator that something is wrong.

The best way to diagnose a check engine light is to bring your vehicle into a Cadillac service center and have the factory trained mechanics troubleshoot the problem. If you are a DIY-type, then you can purchase a code reader that connects to the vehicle's onboard diagnostic port (ODB) to read the codes. The codes can vary depending on the issue and the model of vehicle, so it is important to do your research. There are websites that list common error codes and their likely cause.

Don’t ignore your Check Engine Light

Having your check engine light turn on doesn't necessarily mean there is a major issue with your vehicle, however the warning light shouldn't be ignored. The error could be as simple as a faulty gas cap, but the only way to rule out more serious problems is to track down the source of the error. If the error was caused by something more urgent then ignoring it can lead to an expensive repair bill. If your car or truck's check engine light turns on then it is worth your time to diagnose and fix the issue. The best approach is to have a professional mechanic check the error codes and fix the underlying issue.
