How to Reset the Service Engine Light in a Chevrolet S10
You can reset the service engine light on your Chevrolet S10 by using an OBD-II scan tool. This on-board diagnostic tool can be purchased from your local auto parts retailer, although many such stores will check the code and reset the light at no charge.
The service engine light will turn on at regular intervals when your vehicle needs routine maintenance. After the maintenance is completed you will need to manually reset the light to turn it off. This is an easy adjustment that will only take a few moments.

Look for the OBD II port located near the emergency brake on the lower dashboard. The OBD II port will be the receptive end for the connector on the OBD II scanner tool. Examine the connector end of the tool and the receptive port to make sure you have the correct port. Plug the OBD II scanner tool into the port.
2Close the doors, roll up the windows and turn on the OBD II scanner tool. Put the key into the ignition and turn it to "on," but take care not to start the engine. Turning the vehicle on will start the electrical system which will power the OBD II scanner tool and allow it to do its job. The engine needs to remain off for the scanner to work.
3Wait for the screen on the scanner to stop flashing. The service engine light will have turned off. Turn the key in the ignition to "off" and unplug the scanner.
4Restart the engine and verify that the service engine light is still off on the instrument panel. Turn off the car.

How to Remove an 88 S10 Blazer Catalytic Converter
The catalytic converter on your 1988 Chevy Blazer is located in the exhaust system and is a critical part of the emissions control system for your engine. The design of the converter will reduce pollutants like carbon monoxide and unburned hydrocarbons and stop the escape of these pollutants from the exhaust system. A catalytic converter does not have a life expectancy and should not fail but if it does, the first step in repairing the system is to remove the converter for inspection and possible replacement.

Raise the front end of your Blazer with a jack and support it with a set of jack stands positioned solidly under the frame of the truck. Remove the jack from under the truck so you dont have to try and work around it.
2Locate the catalytic converter in the front of the exhaust system. On the S10 Blazer, it is located just behind the Y pipe where the two down pipes from the engine come together.
3Locate the two mounting bolts on the joint at the rear of the catalytic converter where it meets the exhaust pipe. Remove the bolts with a socket and ratchet and then separate the joint.
4Move to the front of the catalytic converter and locate the tow bolts that attach the converter mount to the front of the converter. Remove the bolts with a socket and ratchet. Remove the exhaust clamp just in front of the mount, using a socket and ratchet to remove the nuts from the cl then separate the two halves of the clamp.
5Separate the catalytic converter from the front pipe by pulling it straight back, using a twisting motion to loosen the catalytic converter from the pipe. Remove the converter out from under the truck and set it aside.
