What to Do When Check Engine Light Comes On 

There are many reasons why the check engine light might come on as you are driving around Appleton. Some are simple fixes, while others are a sign of a serious issue. Here are some possibilities:

  1. Be certain that it is the check engine light: There are so many warning lights on dashboard consoles that it can get confusing. It is easy to mistake the Service Required light, for the Check Engine light. Double-check the owner's manual to be sure you've identified the light correctly. 
  2. Tighten Your Gas Cap: The most common reason a check engine light comes on is a loose or missing gas cap. Remove the gas cap and put if back on. Make sure it is making a secure seal.
  3. Check the Codes: The computer in your RAM 1500 will generate a code indicating the problem that caused the check engine light to come on. The service department at Kolosso CDJR can check the code with an automotive diagnostic scanner. You can purchase a code reader at a Green Bay auto parts store, but unless you are used to working on cars, it's probably a good idea to have it checked by a professional. 

How to Reset RAM 1500 Check Engine Light

To reset the check engine light on a RAM 1500, simply disconnect the negative (black) cable from the battery terminal. Wait for twenty minutes, and then reconnect the cable. This should reset the computer and turn off the light. If the light doesn't go off right away, drive the truck for 50 miles or so. This will recalibrate the computer and turn the RAM 1500 check engine light off. Disconnecting the battery may also reset other electronic systems in the truck, including the security system and clock.
