    The fact that there's a highway to hell and a stairway to heaven says a lot about the anticipated traffic flow.

    Who knows, we can't see what you are looking at

    OBD2 port allows for many things, the protocol is available for reading on Wiki
    What is possible with your vehicle depends on many things

    Always best to find the dealer software and leads
    Jeep are pretty wide spread, one of the Jeep forums must have a copy and appropriate adapter required.


    Some you can do all kinds of things.
    As well as changing the VIN number

    depending on the software and setup you have you
    can also run real time apps on the display.

    i have a 7" eonon stereo so when doing trips i can turn it on
    and run it with real time engine stats showing in
    graphs on the screen.

    Probably the main purpose for having a OBD2 reader would be when your "Check Engine" or another of those fault lights appears
    ABS etc.... You can scan the vehicles ECU and find out a more detailed description of the fault.
    You may also be able to clear the Fault Code and hence reset the Engine Check light on your dash

    A scanner will also allow you to read fault codes thrown that do not illuminate the "Check Engine" light

    If your vehicle has a "Service Indicator" in the dash cluster, you can also reset that after a service

    Also as fandt has mentioned, you can run more accurate gauges too
    EG: My factory temp gauge doesn't move once its got to operating temp, as the range factory programmed in is huge!
    Watching the actual engine temp via OBD2 will show every degree of movement

    First thing i bought for my car, it can read and clear codes, adjust parameters of the CCF (car config file) like adjust the suspension height, change the dash layout, change the lights, reprogram a new key fob as well as live engine data like temp of engine, trans, transfer case etc.

    Out of interest, could you disable the Disco's automatic suspension lowering feature when driving at over 25kph in the highest setting?

    any elm device will perform basic tasks on the jeeo.

    if you want to really do some stuff, get alfa obd for fiat/chrysler products......

    be warned though, you can stuff things up....

    another option which is useful is a Scanguage 2. its a small display which is left plugged into the OBD and monitors a handful of functions at once and can also clear fault codes.
    you need to do a bit of basic data entry but its easy enough. For example in my Prado 2.8 -

    Automatic Transmission Fluid ( ATF )
    TXD 07E02182
    RXF 046105820000
    RXD 2808
    MTH 00010001FFD8

    Torque Convertor Temp ( TCT )
    TXD 07E02182
    RXF 046105820000
    RXD 3808
    MTH 00010001FFD8

    Exhaust Gas Temp ( EGT )
    TXD 07DFO178
    RXF 054106780000
    RXD 3810
    MTH 0001000AFFD8

    Diesel Particulate Filter Temp ( DPF )
    TXD 07DF0178
    RXF 032100000000
    RXD 2010
    MTH 0001000AFFD8
    DPF Level Accumulation Guage ( DPA ) ( in % )
    TXD: 07E02138
    RXF: 032104780000
    RXD: 4008
    MTH: 000200010000 ( x2 % ) or 000100010000 ( x 1 % )

    Fuel Distance To Empty ( DTE )
    TXD 44
    RXF 800000000000
    RXD 0000
    MTH 000000000000
    ATF Temperature A - 150 Series Prado Torque Converter Sensor
    TXD 07E121D9
    RXF 032100000000
    RXD 2808
    MTH 00010001FFD8

    ATF Temperature B -150 Series Prado Ė Oil pan sensor
    TXD 07E121D9
    RXF 032180000000
    RXD 1810
    MTH 0003004DFE70

    I can see all this at a glance while driving
