Reset oil dilution - Subaru - Boxer Diesel Euro 4

imp_mike · **Joined:** Sat Feb 02, 2013 5:50 pm **Posts:** 2

Hi dschultz,

I think there is a big need, to reset the oil dilution ratio, after an inspection on Subaru Boxer Diesel Euro 4 Models.

Is it possible to implement this feature, in one of the next releases of Romraider?

Thank you for your reply!

Same here.
Also interested in that feature, if possible to implement

Cheers

Would be very great! And very helpfull

Yes, this would be great

Maybe, there is also a possibility to implement the feature "Distance since last Regeneration" (EURO 5)
and some other Features :mrgreen:

Yes, that feature would be very very awsome

If I recall correctly to reset that parameter requires the use of a factory service routine which means the program has to first pass a security challenge. To add this to RR requires knowledge of how to exchange and derive the security response.
It may take a while to get this sorted out...

Dale,

I sniffed a oil dilutation reset of a E5 Diesel via CAN.

If the security code of the E5 is the same, or just simular to the k-Line request, I can send you that sniff to take a look to and copy the comans.

On bench, the dilutation will be reseted, if I just replay the sniffed IDs of the tester

Yea, this feature will be great. Thanks for your work, guys.

Hi guys, are there any news about the dilution reset? I checked the release notes but haven't seen a related comment.

I found C-style pseudo code on the Subaru Diesel Crew site but I can't gauge whether the addresses and setting values menioned are correct.

Thanks!

It seems long-time-seems-to-be-death Subaru Diesel Crew gets alive again and got an new post on his side concering the oil diluttion reset

:

Oil Dilution Reset (K-Line, Euro4)

Dale, are this infos enough to implementate the reset into RomRaider software ?
I missed the security code in his description and ask for that.

Maybe you can also try and get in contact with him.
I´ll try to, but do not expact any suggess

Another new hint form subaru diesel crew:

subdiesel never need any security access to reset the oil dilution on his E4 diesel.
The few lines he posted on the diesel block are enough.

Maybe we can try to implementate and test on RomRaider logger ?!

Can you try this procedure with the RR Editor > Tools > Test App ?

Do Init to confirm ECU K-line connection
Uncheck 'Block Read'
Read the address 00027D, 1 byte long
Write the byte data back but with bit 6 set (do not change any other bits)
Read the address, 1 byte long
Write the byte data back but with bit 6 clear (do not change any other bits)
Read the address, 1 byte long and confirm bit 6 remains clear
Ignition off for 20 seconds
Turn ignition on and check diesel oil parameters are reset.

It will be easier to implement this without secure access, but I'm not going to be able to get to it for a few months.

Mhh doesn´t seems to work, but I am not sure, if I unterstand correct:

Maybe it is, because my on bench ECU was allready reseted, but on the other side I expact the chance of bit 6 (starts with bit count 0 or 1 ? from frist or from last bite ? motorola ? )

[edit]
Oh, I set the worng bit, but the result seems to be the same:
after wirting an other string, it wasn´t stored, as you see

Hello,
Looks like the write command is wrong. Should be "0xB8 Write single address" instead of "0xB0 Write memory".
http://www.romraider.com/RomRaider/SsmProtocol

Interactive online conversion tool for bits:
http://www.binaryconvert.com/convert_unsigned_char.html
Look at bottom portion "Binary".

Enter result data byte from read command in the input field to the right of "0x"
Click on those squares below which represent the bits you want to toggle.
In this case, click 7th from right = 2nd from left = bit# 6.
For example, entering 0x12, clicking and therefore adding bit 6 then yields 0x52.

The read cmd looks perfect, reporting byte content "00", therefore setting bit 6 means writing 0x40.

Bit numbers in software development are from right (least significant) to left (most significant), starting with 0 - not 1. A single byte value therefore has bits 0 to 7:

Code:

bit#             7     6    5    4   3   2   1   0
bitmask   hex    80   40   20   10   8   4   2   1
bitmask   dec   128   64   32   16   8   4   2   1

RR will use the write address command for a single byte data payload. Try to un-check the 'Block Read' checkbox.
Also, only send back 1 byte, not all the bytes you read in the read command.
This is not correct:

Code:

SND [Write]: 8010F00BB000027D80F01002E8006A8E
