Help with DME Codes

[Dr.-Ing]

I have a check engine light and my Autel AP200 with Porsche Cayenne specific software is showing the following DME error codes.

005C31 (Please refer to vehicle service manual!)

001DE6 (Please refer to vehicle service manual!)
001DE8 (Please refer to vehicle service manual!)

I can't find a list of DME codes in that format. The lists I have been able to locate predominately show error codes beginning with a P. Can anyone help me translate these codes or give me a hint as to where to look? 

2016 Cayenne S E-Hybrid

Thanks!

Porsche scan tools (PIWIS) translates those into P codes. So all of Porsche's manuals fault tables are in P codes.

I do not know of any outside translation unless Durametric has done that.

Durametric has not done that.

I've emailed Autel support to see if they can help. The Autel device with its Porshe software license doesn't appear to be of much use if it's just going to give me meaningless codes that can't be interpreted.

Diagnostic code information, just like everything else they developed, is considered intellectual property by PCNA, and as such cannot be published or otherwise used without the specific written permission, and most likely payment, to Porsche. If Autel (or any other aftermarket diagnostic tool manufacturer) included that information in their tool, Porsche would most likely sue them out of existence. This has been the problem with every OEM since the EPA forced OBD II standards on them in 1996.

Autel support was a dead end: "As per my response from my engineers, unfortunately we do not have a interpretation for these codes."

 

I would assume that Autel has permission and is paying Porsche, since they charge users a $21.95/year licensing fee for the Porsche specific software.  I do have some non-DME codes that have previously been cleared that are not in P format and their faults are defined. For instance: 000602 (Closed-circuit current, limit exceeded (eEm).

 

But the takeaway is that the Porsche software for the AP200 appears to be able to read Porsche specific fault codes, but is unable to interpret all of them, particularly DME codes.

You assume incorrectly.  If Autel was licensing what Porsche sees as their proprietary copyrighted data, you would be paying a lot more than $22 a year. Last time I looked, PCNA was charging individuals over $5,000 a year to see that data. Yes, you read that amount correctly.

 

It is also a common misconception that diagnostic tools can "interpret" trouble codes, where interpret means give you a decision tree of "do this, if you get that result, replace this" type information. In reality, OBD II diagnostic's tools only identify the codes involved at the moment, nothing more.  Interpretation is then up to the technician and his or her knowledge, or whatever databases they have available to them.  The ONLY Porsche diagnostic tool I am aware of that can both read the code, AND provide you with decision tree "interpretation" pathways to repair the problem is the almighty PIWIS, which is available to anyone willing to pay the $20,000 annual lease to have it at your disposal.

 

Even in automotive diagnostics, "you gets what's you pays for".................

Just to clarify for future readers, I am not looking for interpretation pathways to repair the problem. I'm just trying to find a definition for these codes. I'll update once I'm able to sort them out.   

[JFP in PA]

"Interpretation' is the pathway to repair, the "definition" unfortunately is usually the very first line of that interpretation, and which most find very limiting, and almost cryptic.  Just infuriating semantics, I know, but that is the way the system functions.   Example:

 

 P0430 / Fault Code 45 -Cat conversion bank 2 - exceeds limit value  

Possible causes are:
Exhaust leak
Intake leak
O2 sensor not working properly 
MAF 
Cat not working properly

 

The full read out for the code would then go through how to evaluate and eliminate each of the possible causes and identify the final suspect(s).
