Help Please- Code Deciphering

[ThorneGator]

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.

[ThorneGator]

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.....

[Graeme]

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?

[djam1]

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

[ThorneGator]

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.

[Graeme]

Graeme, I'm wondering if you're the original GC?No, but what a compliment suggesting it as a possibility!

[donh54]

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.

[ThorneGator]

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

I may be barking up the wrong tree (it's happened before!) but it looks a lot like some of the messages I was getting with earlier generation OBD11 scanners on various vehicles (all British/Euro).
The messages are usually a result of the reader getting a response it is not expecting from the vehicle, given the OBD protocol it is using may not be supported by the vehicles' ECU.
The OBD11 compliance requirement was initiated in the USA from around 1980-1981. It has had many variants, but was initially setup to allow testing of emission control (mandated from about 1991) of all cars produced or sold in the USA.
Since V8 Discos/RRs were the only ones sold in the USA, they were the only ones that had to meet that requirement.
Then, just to be difficult, around 2003 the European On Board Diagnostic standard had to be applied to all diesel cars sold in Europe.
Then, in 2008, the USA mandated the ISO 15765-4 CAN Bus as a requirement for all cars sold there.
Since the biggest market, by far, for auto-related items is the USA, most readers (unless specified otherwise) are set up to align with the US standards. Many I have tried over the years simply state they cannot establish contact with the ECU, others come up with outlandish values (210 psi of boost on a naturally aspirated motor comes to mind!).
As soon as I saw things like "Tacho Drive Over Temp Fault Active" I weondered where the hell that reading came from. As far as I can recall, I have never in my life seen a tacho drive that has a temp sensor attached to it!
It would be interesting to find someone nearby with a Nanocom, or IID Tool (both well known to work with LR vehicles) and see what sort of messages they come up with.

Hello.

What ECU version is your vehicle running?
And what Map codes does it show please.

You may need a more specialist diagnostic tool to retrieve these but someone should be near you that could help.

Thanks again, Donh54, this very well may be the correct tree....I will confirm shortly. These codes showed up when I stopped by my LR specialist mechanic on their scanner. The list I put up is the similar list to what they found, but this list is from my generic version. I am going back to my mechanic on the 11th, so I will know more then.
I am inclined to think this is the correct explanation of what is going on, at least for some of the codes. However, if any of you do have an idea of what to check for to validate this, I'm all ears!

Cheers,

[ThorneGator]

This is the same list of codes as originally posted, but I thought it would save going back to the original post to look at them....

As a coincidence today a friend came to me to read the codes from his 2003 defender, most of those codes were present on his as well, after some thinking i've had the ideea to see if the ECU is the original one or a replacement, checked the part number and guess what... it is NNN000130 which was orihginally fitted to D2 automatic so somebody replaced the ECU with an unproper one

So check the part number of your ECU just to rule it out
