You can reset the computer on your '01 Chevy Monte Carlo right from your home garage, saving yourself time and money. The On-Board Diagnostics computer receives trouble codes from sensors positioned throughout the vehicle. These sensors keep track of all the functions of the vehicle and communicate with the computer. When the computer receives a trouble code, it communicates this to the driver in the form of a warning light on the dashboard. You can turn off these lights and reset after you have made repairs.
Put the key into the ignition and turn it to the "on" position, but do not start the engine.
Plug the computerized scan tool into the diagnostic port under the dash. You can buy a computerized scan tool from your local auto parts retailer. Select "PCM" on the menu and then choose "codes." Finally, select "clear all codes."
Unplug the computerized scan tool from the port.
Turn on the engine and observe the instrument panel to make sure all warning lights have shut off. The computer is now reset.
