2019 Ram 1500 Dashboard


Wondering how to reset a check engine light on a RAM 1500? It’s really very simple!

  • Disconnect the negative cable from your battery
  • Wait 20 minutes
  • Reconnect the negative cable

These easy steps should be enough to reset the computer. If you have an older model, it may also be necessary to drive the truck for up to 50 miles to re-calibrate the computer.

Keep in mind that when the battery has been disconnected, it’s very likely that the security system or other electronic systems inside the vehicle will also reset.

As you can see, it is relatively easy to reset the check engine light on a RAM 1500, but it’s very important that you first determine what caused the light to come on in the first place. Westpointe Chrysler Jeep Dodge has the details.

Why is My Check Engine Light On?

Reasons for the check engine light to come on can range from minor issues like not having the gas cap secured tightly to more serious problems such as having a faulty solenoid. At any rate, when you see that the check engine light has been activated, the first thing you need to do is to determine what’s going on.

  1. Make Sure it’s the Check Engine Light: It seems obvious, but with the various warning lights built into new vehicles, it can be easy to mistake the Service Required light, for example, for the Check Engine light. Your Chrysler, Dodge, Jeep, Ram owner’s manual should have a guide that identifies each warning light.
  2. Check the Codes: There are a variety of error codes generated by the computer that pinpoint exactly what is causing the engine light to appear. These error codes can be retrieved by using an automotive diagnostic scanner. Many of these can also clear the code and turn off the warning light. If you feel confident performing DIY vehicle maintenance, you can purchase a code reader to take care of the problem yourself. However, if you are not comfortable with working on your car, the knowledgeable technicians at Westpointe Chrysler Jeep Dodge would be glad to help you figure out the issue.
  3. Check Your Gas Cap: This is the most common reason a check engine light comes on, and it’s the easiest to fix. Access the gas cap, remove it and carefully replace it, making sure that is is seated correctly. Then disconnect the battery, as described above, reconnect it, and the check engine light should turn off.
