Try as we may to keep our Jeep vehicles running perfect, odds are it will 'throw a code' at some point along the way. Basically what this means is your Jeep's computer has detected some sort of problem with a part on the vehicle, and is letting you know via the Malfunction Indicator Light (check engine light). Unfortunately, the light itself does not specify the problem so here is a simple way to find out what issue your vehicle is having:
Insert your key and turn the ignition to the On position without starting the vehicle. Then, push the key into the ignition cylinder and (while holding it in) turn it to Off then On three times - making sure to end in the ON position. The reason to keep the key pressed in while turning is to avoid the key from catching along the way and interrupting the process. When done correctly, as the key finishes in the On position, your odometer will read a series of six dashes, then display a Diagnostic Trouble Code shortly after. Write down this code and reference from the list below.
Now, some people have noted that they are not able to pull the code by moving the key from On to Off, and instead have found success going from On to Acc and then back. However, if neither of these methods work then it is possible the dash code reader is not functioning correctly. There are many different types of programmers and tuners on the market that can help read and clear these codes, as well as providing a host of other fantastic features like calibrating the speedometer following tire or gearing changes, adjusting the vehicle's engine idle to take advantage of accessories like winches, and provide a 'one touch' ability to activate your Wrangler's Daytime Running Lights.
Once you have pulled the code and cross-referenced this list below, you can let your mechanic/dealership know the issue to expedite the repair process.
