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

To reset the check engine light on a RAM 1500, simply disconnect the negative cable from your battery, wait 20 minutes, and then reconnect it. This should reset the computer.

Why Is My RAM 1500 Check Engine Light On?

Reasons for the check engine light to come on are as varied as simply not having the gas cap secured tightly to 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 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 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 it is seated correctly. Then disconnect the battery, as described above, reconnect it, and the check engine light should turn off.
3. 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. DIY types can purchase one of these code readers to take care of the problem themselves. But if you’re like most Addis drivers, you’ll probably feel more comfortable having a professional take care of this for you.
