To find out the specific issue, you need to have the diagnostic trouble codes (DTCs) read. This can be done in a few ways:
* OBD-II Scanner: A relatively inexpensive OBD-II scanner (available at most auto parts stores) can be plugged into your Jimmy's OBD-II port (usually located under the dashboard) to read the codes. These scanners will often give you a description of the code, pointing you towards the problem.
* Auto Parts Store: Many auto parts stores will read the codes for free. They can then help you interpret the codes and decide on the necessary repairs.
* Mechanic: A mechanic will have the tools and expertise to read the codes, diagnose the problem, and perform any necessary repairs.
Ignoring the light could lead to further damage and more expensive repairs down the line. Get it checked as soon as possible.
