Ram 1500 In Desert

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

To reset a RAM 1500 check engine light, the process is simple. Just follow these three quick steps!

  • Disconnect the negative cable from your battery
  • Wait for 20 minutes (or longer)
  • Reconnect the negative cable

Following these instructions should restart the computer inside your RAM 1500. In some older models, it may also be necessary to drive the truck for up to 50 miles to re-calibrate the computer. Note that when the battery has been disconnected it not only resets the computer, but most likely will also reset many of the electronic systems inside the vehicle.

As you can tell, resetting the check engine light on a RAM 1500 is a relatively simple task. However, it’s very important that you first determine what caused the light to come on in the first place. Learn more in this Cecil Atkission Motors Uvalde guide.

Why is My Check Engine Light On?

There are several reasons why the check engine light would come on while driving your RAM 1500. These reasons can range from simple, like not having the gas cap secured tightly, to complex, like having a faulty solenoid. At any rate, when you see the check engine light on your dash, the first thing you need to do is to determine the problem.

  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 RAM 1500 owner’s manual should have a guide to dashboard lights.
  2. Check Your Gas Cap: This is the most common cause of a check engine light, and it’s also the easiest to fix! Simply access the gas cap, remove it, and take care to replace it properly. After doing so, you can reset your light by disconnecting the battery as stated above. If the light stays on, then your issue is something else.
  3. Check the Codes: Your computer generates error codes to help mechanics diagnose problems. These error codes can be retrieved by using an automotive diagnostic scanner, also known as an ODB2 scanner. While you can purchase one of these code readers to take care of the problem, but Del Rio or Eagle Pass area drivers not comfortable with the process can leave it to the certified auto techsat Cecil Atkission Motors Uvalde.
