Service light on dashboard

Curious about how to reset the check engine light on a RAM 1500? The process is actually pretty simple to reset your RAM 1500 check engine light. All you have to do is:

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

By doing this, the computer of your vehicle should reset but do keep in mind that in some older models, you may also need 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 the security system or other electronic systems inside the vehicle, so be aware.

Why is My RAM 1500 Check Engine Light On? 

Now, resetting the check engine light may be a fairly simple task, but it’s important to know what caused the RAM 1500 check engine light to turn on in the first place. That way, the root of the issue can be resolved.

There are a variety of causes for the light possibly turning on, such as the gas cap not being secured tightly or your vehicle having a faulty solenoid. Either way, your RAM 1500 check engine light is something to be taken seriously, which is why you should:

  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 vehicle’s 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 Richmond or Winchester area drivers, you’ll probably feel more comfortable having a professional, take care of it for you.
