That's the computer's way of telling you that something is wrong and it wants you to read the diagnostic code.
That requires an OBDII engine scanner.
I have the check engine light on and the code is for map sensor on my 1999 1500 Chevy suburban
It requires an engine scanner to do that.
How do I reset the service engine light on a 2003 Chevy Trailblazer?
Maybe you should service the engine soon. :P
can you tell me why my 1999-2000 Chevy trailblazer light is on
Check
There is a problem with the emissions system. You need to have the engine scanned with an engine scanner to be able to find out what is wrong and then FIX the problem that made it come on in the first place. Then clear the codes and it will go off.
When service engine light is on on a 2003 Chevy Trailblazer, the problem could be a faulty thermostat, a circuit range performance problem, or any other problem.
That requires an engine scanner to do that. If you don't repaire what made the light come on in the first place it will just come back on.

You need to have it checked for codes to know what the cause of the code is.
Have vehicle scanned to determine the problem and hae codes cleared
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle.
You have to remove the instrument cluster to service the light bulbs.
time for an oil change
I was told by a co-woker that if you disconnect the negative battery cable for about 20 minutes or so that will reset the service engine light.
I reset the check engine light on my jeep by disconnecting it from the battery.
If the check engine light code is "Random Multiple Misfirings", you need a tune up. Have the spark plugs and wires changed. The loss of power is due to misfirings.
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.
disconnect the negative battery cable for 30 seconds
disconnect the battery for a few minutes
Yes it can.
NO.
The service engine light is the same thing as a check engine light.
