What is the check engine light?
The technical name is the “malfunction indicator lamp” (MIL). The MIL indicates when the vehicle’s On-Board Diagnostic System (OBD) Computer has a problem.
What does the OBD system computer do?
The OBD system computer performs a series of ongoing “self-test” to determine whether all systems are working as designed in your vehicle.
Can’t you just turn the check engine light off?
The check engine light cannot be turned off. With more than hundreds of potential codes with numerous combinations of failures, it is necessary to connect a computer scanner to the vehicle in order for the technician to read the codes to make the diagnosis and recommend repair.
Why does it take so long to find out what is wrong?
Specific conditions in the vehicle need to occur while the computer scanner performs its diagnostics. There are many other requirements for each self-test and in some cases some tests must be run more than once before they will register a failure. In other words the technician needs time to correctly diagnose the vehicle accurately.
