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,
Yes it can.
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.
How do I reset the service engine light on a 2003 Chevy Trailblazer?
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.
How do you replace a break light switch on 1995 Chevy Tahoe
can you tell me why my 1999-2000 Chevy trailblazer light is on
Maybe you should service the engine soon. :P
You will have to take the dash apart and replace the bulb.
If the light is not flashing you can drive it until you can have it repaired. If the check engine light is flashing, park it. Otherwise you will do catastrophic damage to the catalytic converter costing several hundreds of dollars to replace.
