How to Reset the Codes on a 1998 Chevy S 10 Blazer

Before you reset the codes on your 98 Chevy S-10 Blazer, you need to have the codes read and have the vehicle serviced or repaired by a qualified mechanic. If you dont, the warning and service lights will turn themselves back on. The functions of the Blazer are monitored by an On-Board Diagnostics II computer. When sensors positioned throughout the vehicle detect a problem, they send a trouble code to the computer, which can then be read using an OBD II scanner. This scanner can be purchased from any auto parts store.

Instructions

1

Open the door on the drivers side of the Blazer and find the data/diagnostic link connector, known as DLC, on the lower part of the dashboard. It can be found near the parking brake pedal.

2

Plug the scanner into the DLC.

3

Put the key into the ignition and turn it to the "ACC" position, but dont start the engine.

4

Press the "Erase" key on the scanner to erase the codes and reset the computer. Each scanner is a bit different depending on the manufacturer. So the code may be "Delete" instead or something similar.

5

Wait for the menu on the scanner to indicate the task has been completed.

6

Unplug the scanner and start the engine. Examine the instrument panel to make sure all warning and service lights have turned off.
