Hi,
To get the light off, and to have it REMAIN off, you will need to have the van connected to a scan tool or code reader to find out what is turning on the light. Once that is done, you can have the fault found & fixed, and then the computer (or shop) will clear the diagnostic code. If the problem has NOT been fixed, then the code and light will come back.
disconnect the battery for 30 seconds
You need to hook the computer up to a scan tool to read the codes. That will tell you why the light is on.
unhook the positive on the battery for 5 min. This should reset your check engine light if it doesnt then you still have issues.
I've got a better question, why is this question in the Chevy venture forum ?
How do I reset the service engine light on a 2003 Chevy Trailblazer?
If the check engine light is blinking that means an engine cylinder misfire has been detected
I have a 2000 venture and the traction control light came on. Where do I look first, hubs. Wiring.
Disconnect the battery for approximately two minutes.
Maybe you should service the engine soon. :P
can you tell me why my 1999-2000 Chevy trailblazer light is on
Check
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.
