    Help Please- Code Deciphering

    G'Day all,

    I just run a scan, and have returned with a number of codes, many of which seem to be repeated. I don't see a common pattern with the codes, and nor am I having issues with these parts of my vehicle at the moment. Would any of you mind taking a look at the codes, and suggesting something that you think would help. I figure between all the minds on here, something is bound to have been seen before, etc....

    Perhaps you should clear the codes then see what re-appears in a day or 2 as those codes may have been there for a long time.

    Thank you, Graeme for such a quick response. If this helps, I have cleared them, and then re-interrogated for codes, and was given this list again. I did this three times, just in case there was some 'whitchery' occurring inside the ECU.

    I know it could be any number of causes, but right now I am trying to find common or shared traits with these. For example, a common ground wiring, or ECU pins on a shared row, etc, etc.....

    Are you listing all possible faults or logged faults?

    Edit - I just had a proper look at the list.

    Does the vehicle have problems for which you're trying to find the reason?

    Does the car have Disco transfer gearing?
    This would explain the cruise control error
    The rest of it seems to be drivel
    Has it been remapped I have seen nonsense errors when the wrong map is loaded but it doesn’t seem to effect the car

    Thanks both for your response and help.
    She is running pretty well actually, plenty of power, response, sounds smooth (for a diesel), so no issues that I am trying to track down; just being pedantic.

    The remap may be an issue..... I had the vehicle remapped about 7 years ago. It could be that the remap is causing these codes. The error codes may be unavoidable, but I have had all work done by Graeme Coopers in Sydney (Graeme, I'm wondering if you're the original GC?), so I have the utmost trust in their work.

    There is no disco transfer gearing in there, but I do have a Roamer Drive in there. I never drive it over 110 (unless necessary), but maybe that code is related to speed/rpms?

    If I have to just live with it, I can, but I always have to ask if it can be fixed, how?

    Really appreciate all of your help....

    Hi. First of all what kind of scanner was used? ... if by any chance it was ICarsoft or other so called dedicated LR but mainly OBDII reader forget about that list, most of them are false and generated by the unproper diagnostic protocol.

    No, but what a compliment suggesting it as a possibility!

    Are those codes coming up (a) just with the ignition on, (b) engine running at idle, or (c) whilst you are driving down the road? Also, are these stored fault codes, or just what comes up as the system starts its normal processes?

    Theoretically, with all those faults, your car should not be running at all!

    I would agree with Tombie, if it is a "generic" code reader. Find someone with a diagnostic tool specifically for your model LR, and compare readings.

    Thanks again to all,

    In short, yes. It is a generic diagnostic tool (Foxwell NT510). It had good reviews for the Defender, but I realize its shortcomings. I purchased it after my mechanic showed me the codes on their scanner, so I know they are there. I have cleared them numerous times, but they always remain. They show up with the engine running at idle (option b).

    I was at the mechanic for other bits and items, when the codes showed up, and with their busy schedule, they just recommended I have a go at it before booking in. It is strange that the vehicle is running so well, but with so many codes; making me think it is more about computer glitches than anything. But if I understood the codes a little better, then maybe I might find the common issue causing so many "over temp" and "open load" faults.

    Cheers,
    Taylor
