check engine light on

Oh no, your RAM 1500 check engine light is on! What should you do? Pull over and wait for a tow truck? Ignore the light altogether and continue on your merry way? It’s generally a good idea to find out why your check engine light is on. But most drivers know there can be several reasons for the light to flash that aren’t immediately serious. That’s why some of our Hudson customers try to reset the light themselves. Before you decide to abandon your pickup along the side of the road, read the handy guide below on how to reset the check engine light on the RAM 1500.

Check Your Fuel Cap First

Believe it or not, the RAM 1500 check engine light can sometimes be triggered by a loose fuel cap. This is true of most vehicles. So, check the cap first. Remove it, then screw it back on tightly. If the cap is the cause of your check engine light coming on, the light should go back off once you’ve driven about 10 to 20 miles after doing this.

How to Reset the Check Engine Light on a RAM 1500

If a mechanic has confirmed that your RAM 1500 check engine light has been triggered by something that is not serious, follow these steps on how to reset the check engine light on a RAM 1500:

  • Make sure the ignition is turned off.
  • Find the negative (-) post on your truck’s battery. It will be the terminal that does not have the red cover.
  • Disconnect the negative terminal. Leave it disconnected for about 20 minutes.
  • Reconnect the negative terminal.

When You Shouldn’t Reset the RAM 1500 Check Engine Light

There could be a serious issue that needs attention. Fortunately, you can schedule an appointment with our Service Department which specializes in servicing and repairing your truck. After all, you don’t want to find yourself broken down somewhere around Amery.
