Usually you can simply disconnect the negative battery terminal (while vehicle is not running), wait a few seconds, then reconnect it. I've used this to reset the warning light on a 1989 Chevy pickup (and other makes & models).
The only way to erase the check engine light on a 96 and newer vehicle is with a SCANNER ALL 96 and newer cars, truck, and SUV's have a computer that's called OBD II (On Board Diagnostics generation 2) The "remove the battery cable trick" only works on some 95 and older vehicles
Disconnect the neg battery terminal, wait 15 mins, then reconnect, but DO NOT START YOUR TRUCK! wait 30 mins then start.....Why? you ask, computers in Chevys and Fords had about a 100th of the speed as your desktop computer, so when the battery is reconnected it takes about 20-30 mins to reboot properly.....also you will get better gas mileage...at least 2mpg better.
These may work; I don't know. I do know if it works, but the actual problem that caused it to come on isn't fixed. It will come back on again when computer reads it.Most autoparts stores will do a free check on your car with an OBD reader. It will tell you what's wrong; could be a bad censor to your fuelcap being loose. Try that route for permanent fix.
disconnect the battery for a few minutes
why appear light ( service engine soon), after change oil on a 2001 ford pickup (f150)?
How do I reset the service engine light on a 2003 Chevy Trailblazer?
Check your gas cap. Make sure the seal is still good. This will cause the check engine light to stay on and is an easy fix.
Have vehicle scanned to determine the problem
Maybe you should service the engine soon. :P
can you tell me why my 1999-2000 Chevy trailblazer light is on
bring the truck to autozone and let them reset it with their scn tool for free.
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 OBDII engine scanner.
I'm no expert, but I think it's trying to tell you to service the engine soon. im no car expert either but from what i know is that the check engine light can come up for various reasons. sometimes its not even important to have it checked because itll just light up for something small. its always good to have it checked out though.
The engine coolant temp sensor can do that. If you have a check engine light on, have the codes read.
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.
That requires an OBDII engine scanner to do that. But it will not do any good to reset it if you did not fix the problem that made it come on in the first place. It will just come back on. NEED to scan the engine to see whats wrong with the emmission system.
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.
Yes it can.
The service engine light is the same thing as a check engine light.
Have vehicle scanned to determine problem
