It doesn't mean a specific problem; it means there's a problem that needs attention.
To find out what's causing the light, you need to get the diagnostic trouble codes (DTCs) read. This can be done in a few ways:
* OBD II Scanner: The most common and reliable method is using an OBD II code reader. These are relatively inexpensive and widely available at auto parts stores. The scanner plugs into a port under your dashboard (usually near the steering column) and reads the codes stored by your truck's computer. The codes will give you a much better idea of what's wrong.
* Auto Parts Store: Many auto parts stores will read the codes for free. This is a convenient option, but they might try to sell you parts to fix the problem, even if it's not necessary.
* Mechanic: A mechanic will have the tools and expertise to diagnose the problem accurately and make the necessary repairs. This is generally the most reliable option, especially for less common problems.
Ignoring the light is not recommended. Driving with the light on could lead to further damage, decreased fuel efficiency, and potentially unsafe driving conditions. The sooner you get it diagnosed and repaired, the better.
