How Do I Reset the Check Engine Light on my RAM 1500?

There are three easy steps to reset a check engine light on a RAM 1500:

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

That’s all you need to do! However, if you have an older model, it’s possible that you may need to drive the truck for as much as 50 miles to re-calibrate the computer of your 1500.

*Just a note – If you disconnect the battery, it’s likely that it will also reset the security system or other electronic systems inside the vehicle.

It’s very simple to reset the check engine light on a RAM 1500, but it’s also important that you find out what caused the check engine to become illuminated.

Why is My Check Engine Light On?

What are some of the reasons for the check engine light to come? It can be something as simple as a loose gas cap, or something much more serious. Keep these tips in mind:

1. Ensure it’s the Check Engine Light: With so many different dashboard lights, it can be easy to mistake one of the other warning lights for the check engine light. If you are unsure exactly what your check engine light looks like, consult your owner’s manual.
2. Check Your Gas Cap: Oftentimes, a loose gas cap is the culprit. Simply re-tighten the gas cap and you should be good to go. Then disconnect the battery, as described above, reconnect it, and the check engine light should turn off.
3. Check the Codes: The computer in your vehicle will generate error codes to make it easy to diagnose what’s causing the issue. 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. You can purchase one of these automotive diagnostic scanners if you would like to do your own vehicle maintenance. However, if you are unsure about performing this task, the experts at the Cornerstone Chrysler Dodge Jeep Ram service center would be glad to do it for you.
