How To Reset The RAM 1500 Check Engine Light

To reset a RAM 1500 check engine light, all you have to do is:

  1. Disconnect the negative cable from your battery.
  2. Wait 20 minutes.
  3. Reconnect the negative cable.

This should reset your RAM 1500 computer. In some older models, you may also need 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 not only resets the computer but will most likely also reset the security system or other electronic systems inside the vehicle. You may need to reset your car alarm and reprogram your radio to your favorite channels after resetting the check engine light.

Why Is My Check Engine Light On?

There are varied reasons for the check engine light to come on in your RAM 1500. Some instances could be small things you can fix at home, like tightening your gas cap. Others may require a visit to a service center to repair or replace a part before you head out to tow or haul. At any rate, when you see that the check engine light has turned on, the first thing you need to do is to determine what the problem is.

  1. Make Sure it’s the Check Engine Light: This 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, Wagoneer 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 can 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 Orland Park or Mokena area drivers, you’ll probably feel more comfortable having a professional, such as the certified auto techs at Bettenhausen CDJR, take care of this for you.
