There is a pretty standard procedure for resetting the security in GM vehicles. This is it.
Perform the re-learning procedure
Start the engine (the vehicle has now learned the Sensor Data Code and/or password).
Your specific vehicle does not actually claim that this works. This is for a few years after your vehicle, but it is worth a try. If it doesn't work, then you may actually have a failure on your hands that needs to be addressed. More info on this site. http://www.diy-gm-security.com/
Reset. Turn the key on for ten minutes, off for thirty seconds. If it doesn't start there is a relearn. It is three times this, try to start after the third time. Have a battery charger on it. This only works if there isn't a problem in the security system. If the battery gets to low or you accidentally hit the starter at any time, you have to start over.

I think that there is a button located under the dash at the right side of the steering column. To reset the low tyre pressure warning you need to press the button immediately after inflating all tyres to right pressure.

Do an engine oil change and filter change.
Get some OBD2 codes for the time being to see the what is the problem.

Hello! This indicates a fault with the wheel speed sensor/ABS sensor. Any major auto parts retailer can pull the details of this code (which sensor) for free, which will help you identify if the wiring is loose or damaged or if the sensor will need to be replaced. If you need to replace the sensor - you will need to replace the entire wheel bearing assembly, as the sensor is internal.
Thanks for using FixYa!

Check for
vacuum leaks on intake manifold,
the air tube between the air filter.
intake manifold vacuum hose.
===
clean throttle plate with Berryman carburator cleaner
SEE sample picture HERE
===
Also remove carbon built up behind the EGR valve and the EGR passage tube.
===
Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.
More un-metered air (leaks) will lean out the fuel mixture.
Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.
At idle,just spray and listen for the RPM surge.
The in-rush of carb clearer will increase the RPM on the motor.
Record the problem spot(s) and address it later.
===
EGR carbon built up require 2+ hours to clean from start to finish.
You will need a new EGR base gasket before your start.
Locate and remove the EGR valve after the vehicle is cool down.
Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.
Remove the EGR valve.
Inspect the location of the carbon built-up inside the valve and the EGR passage tube.
SOAK these areas with WD-40 spary.
You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.
RE-SOAK the carbon and let it sit for over-night will also help.
One the last round,pass a shop vacuum of the EGR valve and the passage pipe.
Install the new EGR gasket and connectors.
Allow the vehicle to warm up outdoor to burn up any remaining WD-40.
Take it for a test drive.
Please rate my answer if it's useful to you.
