DAD Diagnostic Codes you can *ignore*

You may recall I posted special info for owners of '03 Sprinters. These '03 ECMs have a series of fault codes which are meaningless for diagnostics. They are easy to identify and will not erase.

These include:
1400
0203
0300
412
1802
7312
00DF
A2-00 (also A2-000 or 00A2 )http://sprinter-source.com/forum/showpost.php?p=80325&postcount=150

Carefully log all codes in your notebook, erase and identify these 'permanent' codes if you own an '03. Then ignore them as they are not significant.

per http://sprinter-source.com/forum/showpost.php?p=85648&postcount=237
P60C7
P0114
You can add those 2 codes to the '03 ONLY, ignore list.

The '03 ECM reports numerous vendor and calibration codes (related to sensor sampling) which are NOT MBenz DTCs. Why these 2 codes came up in a later scan is of interest.

per http://sprinter-source.com/forum/showpost.php?p=77983&postcount=7 and http://sprinter-source.com/forum/showpost.php?p=78573&postcount=46:
The B1010 IC code is a common low voltage code that often appears in the IC.
(Added by Dick: it seems to be an ignorable code, if it doesn't return after clearing)

re: P1926 CAN communication with other control units installed is not possible

per http://sprinter-source.com/forum/showthread.php?p=81835&highlight=1926#post81835:
The P1926 SLA (shifter module) fault code is one we can all document and ignore. It has no relevance for Sprinter owners.

(also apparently appeared here http://sprinter-source.com/forum/showpost.php?p=78095&postcount=17 as a C1926, and is mentioned in http://sprinter-source.com/forum/showpost.php?p=78129&postcount=27)

...that takes us up to message #259 in the DAD user's thread. (13 Mar 2010)

p.s. also see Sikwan's DTC explanation and lists:

p.p.s. ESM, EWM and SLA are the same module

NAFTA WIS info on

Chassis 903
ECM/ESL
EWM210

P1926 info below
22004


Is this the same kind of info (acronyms, terminology, etc) that is displayed in "DAD?"

I'm just wondering if DAD users can leverage WIS w/o having to innundate Doktor A with questions....

Thanks for that...
Leaving aside the typo of P1926 magically becoming P2126 in your file name... :smilewink:

All that DAD says is:
P1926 CAN communication with other control units installed is not possible
Sprintertekinfo.com -would- help by serving as a deep-knowledge lookup for (one hopes) -every- code that DAD might report.
Its diagnostic information (using that page as an example) is a bit better than the diagnostic pages in (at least) the 2004 Service Manual, since Sprintertekinfo combines the circuit diagram with the analysis, instead of expecting you to flip to page 8W-mumble of the Service Manual.

But P1926 is not a good herring to chase (it's a real code)... please try the list from the 2003, such as P00A2 or P00DF
What does Sprintertekinfo say about -those-?

P1926 is listed as a "code we can ignore", since Andy sez so. (although that's an evolved response...in the early days of DAD he treated it as a "real" Fault).
Many people (like me) see the code (but not -everybody-, which does bother me a tiny bit).
No other portion of DAD reports anything amiss in the ASP/ESM(SLA) EWM group, so i -am- inclined to believe that it's a false positive flag (i.e. ignorable).
---------
As an aside, the first page you post has some lines like "Cable A40/7 - J378 has [ ]+ or [ ]- -//-"
I assume those fields have voltages or something in the real page, or are they blank on your screen too?

thanks

I found some stuff on DTC 203 - for 2003 model years...

Let's take this over email so as to not clutter the thread too much.... :)

I'll send you some stuff and you can decide if it's a waste of time, or if it's useful information that, with some polish, might be useful to the forum or at least to DAD users.

I'm multitasking right now.... recreational stuff like this while I wait for other propeller heads to tell me it's time to get dirty.

P1926 is a shifter CAN communication loss code used on MBenz sedans but not applicable to the NAFTA T1N Sprinter. Doktor A

Finding these codes are meaningless is good: other codes to be fixed - P0203 (have I ever mentioned that Dishman Dodge will not get my business again "sometimes the light stays on") the #3 injector is not working. Maybe I'm glad that they did not attempt to fix. :) Special thank to Andy for procuring and making these available.

The Vol. 1 ('01-'06) and Vol 2 ('07-'10) Sprinter complete fault code books are available from me directly. If a particular code is not found in the book, it can be ignored. Doktor A
