1. To check your Jeep JK Wrangler’s DTC codes, simply insert your key into the ignition, turn it to the ‘ON’ position but do not start the engine. Then, push the key into the ignition cylinder and while holding it in, turn it to the ‘OFF’ position and then back to the ‘ON’ position (3) times straight making sure to end with it in the ‘ON’ position. It is important to keep pushing in on the key to prevent it from catching at the different positions along the way. |
 |
2. If you do step #1 correctly, all your dash lights will illuminate and your odometer will show up as a series of (6) dashes as shown in the pic to the left. If your Jeep JK Wrangler has any logged in any DTC’s, they will be displayed soon after the dashes appear. Write down the DTC(s) and check it/them against the list below to find out what they mean. |
 |
3. If your Jeep JK Wrangler has not logged in any DTC’s, the dashes on your odometer will be followed by the message ‘-done-‘. Turn your key to the ‘OFF’ position and you will in fact be done. |

Hey Krag waits….did you ever figure out what was going on with your rubicon? I think I may have the same issue and you might be able to help me out.

I went through these steps and got the dashes but then no codes. Just went to “done”. Engine light is still the on. Any thoughts?
Codes PO507, C221C, P2173, P0513, B210D I know what they mean but what is causing them?
