If you’ve ever been greeted by that pesky Check Engine light on your Cadillac, you know it’s like a stubborn relative—it shows up uninvited and refuses to leave.
Before you panic and schedule an expensive dealership visit, here’s the truth: many times, it’s something simple, and you can reset it yourself.
Step-by-Step Guide:
-
Check the gas cap – Believe it or not, a loose gas cap is one of the most common causes.
-
Disconnect the battery – Pop the hood, disconnect the negative terminal for 15 minutes, and reconnect it.
-
Use an OBD-II scanner – Plug in, read the code, fix the issue, and clear the warning.
Pro Tip:
If the light comes back on immediately, it’s not just a glitch—there’s an actual issue. In that case, don’t ignore it.
