Here's the proper approach:
1. Diagnose the Problem: The first step is to determine *why* the check engine light is on. You have a few options:
* OBD-II Scanner: This is the best approach. Buy a relatively inexpensive OBD-II scanner (available at most auto parts stores) and plug it into your car's OBD-II port (usually located under the dashboard). The scanner will read the diagnostic trouble codes (DTCs), which will give you a clue about the problem. You can then search online for the meaning of the specific codes.
* Auto Parts Store Scan: Many auto parts stores will scan your car's OBD-II system for free. They can tell you the code(s) and might even offer suggestions on how to fix the problem.
* Mechanic: If you're uncomfortable diagnosing the problem yourself, take your SRX to a qualified mechanic. They have the tools and expertise to accurately diagnose and repair the issue.
2. Repair the Problem: Once you know the cause of the CEL, fix the problem. This might involve replacing a faulty sensor, fixing a leak, or performing more extensive repairs.
3. Clear the Code (After Repair): *Only after you've addressed the underlying issue* should you clear the code. Many OBD-II scanners have a "clear codes" function. Some higher-end scanners even allow you to clear specific codes. Alternatively, disconnecting the battery's negative terminal for a few minutes will often clear the codes, but this is less reliable than using a scanner.
Important Note: Simply disconnecting the battery or using a generic "check engine light reset" tool will only temporarily clear the light. The light will return if the problem isn't fixed. This is a dangerous practice because it masks a potential problem that could lead to further damage or safety hazards. Always address the root cause of the check engine light before attempting to reset it.
