How to Access Jeep Liberty Error Codes
You can access your Jeep Libertys error codes from your home, saving you time and money. Jeeps manufactured after 1996 come equipped with an On-Board Diagnostics II computer (OBD II) that retrieves and stores all trouble codes sent to it from sensors positioned throughout the Jeep. Jeeps manufactured 1996 or earlier come with an OBD I computer. When these sensors detect a malfunction in the vehicle, they send a code to the computer. The computer then illuminates warning or service lights on the instrument panel. You can retrieve these error codes using a small computerized device called an OBD I or II code scanner, which you can purchase at any auto parts retailer or online.
Instructions
- 1
Find the OBD port on the drivers side dash underneath the steering column. It is the same size and shape as the connector on the OBD code scanner.
2Plug the code scanner into this port. Turn the key into the ignition to the "ACC" position but dont start the engine.
3Wait while the code scanner powers on. Find and select "Read Codes" or a similar type of command. Wait while the code scanner interfaces with the computer. When it displays the codes, write them down on a piece of paper.
4Look up the meaning of the codes in the manual. Unplug the scanner and take the Jeep to be serviced or repaired using the information obtained from the codes.
