Don't reset the OBD ll codes in a Jeep Liberty CRD without first addressing the root of the engine trouble, unless you're convinced the code was stored in error. Resetting the codes is relatively easy. A hand-held scanning device designed to interpret and clear OBD ll codes, rather than the older OBD l codes, is your best bet for the job, although other methods also work. Scanners begin at around £13 as of 2010, with more sophisticated models costing quite a bit more.

    Resetting the Code with a Scanner

  1. 1

    Locate the ALDL (Assembly Line Diagnostic Link) under the dash near the steering column. It's a small 12- to 16-point electrical port, sometimes with a plastic cover on top.

  2. 2

    Connect the OBD II scanner to the ALDL. Turn the ignition key to the "On" position.

  3. 3

    Follow the prompts on the scanner to retrieve stored error codes. Select the option to reset the codes.

    Resetting the Code Without a Scanner

  1. 1

    Wait for the codes to clear themselves. Chrysler vehicles automatically reset the error codes after the engine has been run successfully 40 times.

  2. 2

    Crank the ignition on the Jeep. Drive forward a few feet, then drive in reverse a few feet. Repeat this three times, then turn the engine off. Crank it again and check the dash panel. The OBD II code should be cleared.

  3. 3

    Disconnect the battery for a few minutes to manually reset the OBD II code. Disconnecting the battery also clears other electrical components, such as the clock, radio settings and saved seat settings.

Tips and warnings

  • Take your Jeep to an auto parts store, such as Advanced Auto or Auto Zone, to have the OBD II code reset free of charge.
