Here's the proper procedure:
1. Diagnose the Problem: The first step is *not* to reset the light. You need to find out *why* the light is on. You can do this in a few ways:
* OBD-II Scanner: This is the best option. A relatively inexpensive OBD-II scanner (available at most auto parts stores) will read the diagnostic trouble codes (DTCs) stored in your S-10's computer. These codes provide clues about what's wrong. You can then look up the codes online to get a better understanding of the issue.
* Auto Parts Store Scan: Many auto parts stores will scan your car for free. They can tell you the code(s) and possibly suggest a solution.
* Professional Mechanic: If you're not comfortable diagnosing the problem yourself, take your S-10 to a qualified mechanic. This is the most reliable method, but also the most expensive.
2. Repair the Problem: Once you know the DTC(s), address the underlying issue. This might involve replacing a sensor, fixing a leak, or performing more extensive repairs.
3. Clear the Code (After Repair): *Only after you've fixed the problem* should you attempt to clear the code. Many OBD-II scanners have a function to clear codes. Some even automatically clear them after a successful repair and a certain number of drive cycles without the fault reoccurring.
* Disconnecting the Battery: A temporary "reset" can sometimes be achieved by disconnecting the negative (-) battery terminal for about 15-20 minutes. However, this is not a reliable method and might not clear all codes, and it *will not fix the problem*.
Important Note: Simply resetting the light without fixing the problem will only temporarily hide the issue. The light will likely come back on, and the underlying problem could worsen, potentially causing more serious damage to your vehicle. Always address the root cause before attempting to clear the code.
