When something is wrong internally with your truck, its sends a computerized "code" to your electronics system and the code reads the problem which is what makes the light flash or turn on. Mine has been on for 3.5 years, and i know its the slipped gears in my transmission, so when you take it in to get fixed, they find the problem and reset your computer system to not say "service engine soon"! NEW ANSWER: Put your key's in your pocket, Then unhook the NEG. cable on the
battery for at least 30 MIN. This will clear the codes on this year truck. Hook cable
back up and start engine, light will be off. But if you did not fix the problem that
made the light come on in the first place, It WILL come back on,
Service Stability light come on
THE EASIEST WAY TO DO IT YOURSELF IS TO UNHOOK THE BATTERY. iF YOU DO HAVE A PROBLEM THOUGH, THE LIGHT WILL COME BACK ON.

A person can reset the service engine light in a 1998 Tahoe by disconnecting the battery cables for 1 minute. After the battery cables are reconnected, the light should turn itself off.
You need a scan tool. However, you should not turn off the light without repairing the problem that is causing the light in the first place.

The check engine light means there is a problem with the emission systems on the vehicle. The service engine light means that a regular schedule service is needed. Most of the time this means you need an oil/filter change.
The service engine light is the same thing as a check engine light.
disconnect the battery for a few minutes
An emission or performance problem will cause the Check Engine Light to illuminate. You can take your vehicle to Auto Zone and have the computer scanned for trouble codes. There is no charge.
