How Did the Light Get Turned On?

The Importance of the Second Generation
Also called the MIL (Malfunction Indicator Lamp), the check engine light most of us know today is actually the second generation of this warning signal. OBD stands for On-Board Diagnostics. The OBD-I, or first-generation, was available on some vehicles in the 1980s and first half of the 1990s. The information provided by these diagnostic systems tended to be specific to particular manufacturers. Therefore, when the OBD-I triggered a warning that illuminated the check engine light (which also may say Service Engine Soon), the resulting trouble code was not generalizable across automakers. The Environmental Protection Agency (EPA) mandated that all cars model years 1996 onward have a universal coding system to help control emissions by alerting drivers to problems and identifying the general source of malfunction. Thus, the OBD-II was born. These newer computers generate trouble codes that are the same for similar problems regardless of the make you drive.
Making Repairs and Making the Light Go Out
When you take your car or truck to a service technician with an illuminated check engine light, he or she will connect the vehicle to a computerized code reader. This machine will give the mechanic a trouble code that identifies the category to which the problem belongs. Some customers mistakenly think that the trouble code reveals the exact nature of the malfunction. It does not. That’s why it’s important to use an auto repair shop with trained, experienced professionals. Based on the trouble code and their own knowledge, the technician will determine the issue that needs to be repaired and then fix it.
