OBD2 Fault Codes - Remote or Local

[MrNatural]

Hi Guys,

Can anyone enlighten me please. Here is an example of some OBD2 faults. ( I fixed the problem which was a lack of turbo boost from a VGN turbocharger causes by a break in the reference live to the turbo boost control valve.

What a don’t understand yet is the difference between a remote and local fault. Can anyone enlighten me please?

Could remote mean history and local mean current? I have never seen those before.

I'd go into the generic side and see what is stored. Being that there is a P1XXX code I assume you're in manufacturer specific data?

I've never seen a listing like that in any of the tools I've used.

Thanks for your input. I wondered that myself though I don’t think that’s the case as all faults were cleared immediately before the scan. Ie: they are fresh faults.

Hi. Thanks for your thoughts. The OBD2 reader is an Autel AP200 where you pay for each individual marque. In this case it’s Fiat though I have seen the same with other marques downloaded: VW, Mercedes, Peugeot, Renault, Mini.

Therefore I think it’s peculiar to Autel.

So it doesnt have access for generic or global obd2? That would likely clear up some confusion seeing what is stored there.

That’s really interesting and it had not occurred to me.

Yes: without any individual marques paid for and downloaded, the Autel ap200 does have a generic scanner function. If I understand you correctly, you think that a local code is one found in the individual marque software, and a remote code is that picked up by its generic code reader function?

I thought we had it there but I checked a scan of the same vehicle back in June. It had the same faults though listed as local not remote so I guess that rules it out being generic data?

Current codes should be found in global or generic OBD2. Sometimes history codes will stay as current on the manufacturer side. Comparing the list of global OBD2 codes to your list of manufacturer specific codes they offer insight into what the local/remote stuff means.

Thanks Scott. I will try two scans on a different vehicle tomorrow. One marque specific, one global/generic and see if I can pin codes down to each. While I am at it I will also try and find a way of identifying historic as opposed to live faults.

Regards for now,

Mark

The Local/Remote thing is specific to the scan tool you are using

If you look up the DTC description it doesn't include that phrasing

I've never seen it on any scan tool I have used

Do you have any Autel instructions/user manual??

Hello again.

There is an online manual though it doesn’t address this point. One of life’s mysteries - I will shoot Autel an email ( based in China.)

Enquiring minds need to know.
