Gm bcm and cluster can bus messages through eml327 script

[04colyZQ8]

I can`t stand that elm torture, It looks like elm is really slow on can and can`t format longer messages, I did some testing with an obdlink device with it extended ST command set, but also got some error FC error. So i also gave up on it.

Here are some presets configuration for connecting j-device with universal patcher.
first is in raw can it will open connection and set filters for communication with all modules on bus, but filter idle data.

second is to connect to bcm in iso15765 protocol and send and recieve data.

Use the load button per the screenshot to load the configurations, select device and click connect.

this is what I get for the bcm

a bunch of errors ?

Looks like mongoose is POS and don`t support what mdi does, Anyway you can try removing one of the filters

Go to filters: and click edit button, Than select the box with this filter

Mask:FFFFFFFF,RxStatus:NONE,TxFlags:NONE
Pattern:00000241,RxStatus:NONE,TxFlags:NONE
FlowControl:00000641,RxStatus:NONE,TxFlags:NONE

click Clear button , than OK.
Than when pop window closes click Apply next to EDIT button
save config and try again.

If still errors delete the other flow control filter, leaving the other.

Here is the test config if you want to test it.

Some screensshot.

In case you want to log PRogram->j.dll communication and how filters are set

Use the second program from screenshot, than open the log file and and can find how a j2534 program sets the filters

for example

Than you can set the same filter in universal patcher with that arguments.

sent this email to eml 327.. log shot in the dark..

Hello I am trying to write the Vin to a body control module using eml37 commands. I was not able to read multi-line responses without custom flow control settings.


>AT Z
>AT SP6
>AT SH 00 02 41
>AT CRA 00 00 06 41
>AT SH 241
>AT FC SH 241
>AT FC SD 30 00 00
>AT FC SM 1

Than I type

>1a90
013
0: 5A 90 31 47 43 50
1: 54 45 45 31 32 4A 31
2: 32 32 33 36 30 38 31

And
>ath1

>1a90
641 10 13 5A 90 31 47 43 50
641 21 54 45 45 31 32 4A 31
641 22 32 32 33 36 30 38 31

To write the vin I need to send 3B 90, but I am unsure as to how write multiline

I need to send this
241 10 13 3B 90 31 47 43 50
241 21 54 45 45 31 32 4A 31
241 22 32 32 33 36 30 38 31

I tried..

>AT CAF0
>AT CFC0
>10 13 3B 90 31 47 43 50
641 30 00 14 33 36 30 38 31

>21 54 45 45 31 32 4A 31
NO DATA

And here is the issue I think it is not allowing me to send “21 54 45 45 31 32 4A 31” because it expects the length byte
First like this should be 10 21 54 45 45 31 32 4A 31, but that is to long so I cut off the last byte and send 10 21 54 45 45 31 32 4A,
Which does go through but I don’t like it like that! Because instead of sending it in 3 lines like it should be done . I have to send it in 4 lines.. like this.. than pad the end with zeros!

>10 13 3B 90 31 47 43 50
641 30 00 14 31 36 30 38 31

>10 21 54 45 45 31 32 4A
641 30 00 14 31 36 30 38 31

>10 22 31 32 32 33 36 30
641 30 00 14 31 36 30 38 31

>10 23 38 31 00 00 00 00
641 30 00 14 31 36 30 38 31
Is there anyway I can send direct messages without using header “AT SH 241” so I can send exactly this?

>241 10 13 3B 90 31 47 43 50
>241 21 54 45 45 31 32 4A 31
>241 22 32 32 33 36 30 38 31

Or


>00 0241 10 13 3B 90 31 47 43 50
>00 0241 21 54 45 45 31 32 4A 31
>00 0241 22 32 32 33 36 30 38 31


I have looked everywhere on how to send direct messages but have come up with no answers.
Thanks,
Jamie

save config and try again.

If still errors delete the other flow control filter, leaving the other.

I cleared both filters and now it says this ..

With iso15675 protocol you need to set at least 1 flow control filter. No filters= device initialization failed.

Test the file I attached earlier.

With CAN_gm_query.xml config you can send and recieve data from all modules connected on bus using raw CAN formatting.

For writing the vin.
Are you unlocking the module first?
Have you cleared DTC's?? Some modules refuse a vin write without it for some reason
After you send the first vin write line and get back the 30 response how quickly are you sending the 2nd and 3rd line? Needs to be very quick.. in the millisecond range..
After all this, the BCM may be locked and may not let you write/change the vin.. To check this I try to write back the vin that is already in the module.. If I get back a successful write response then I know my code is ok.. IF it refuses to write a different vin than you gotta dig deeper as to why it's not allowing it.. First get a successful write vin with the same vin in the ecu first..
gotta walk before you can fly..

Yes but the biggest issue is how to actually send the vin split up using the elm
Because it should be
10 13 3B 90 xx xx xx xx
21 xx xx xx xx xx xx xx
22 xx xx xx xx xx xx xx


But instead I have to send

10 13 3B 90 xx xx xx xx
10 21 xx xx xx xx xx xx
10 22 xx xx xx xx xx xx
10 23 xx xx 00 00 00 00

Is it ok to send this way?


Either I don’t know what setting to use or the elm just flat out won’t let you send

10 13 3B 90 xx xx xx xx
21 xx xx xx xx xx xx xx
22 xx xx xx xx xx xx xx

Or ideally I would send this ..

241 10 13 3B 90 xx xx xx xx
241 21 xx xx xx xx xx xx xx
241 22 xx xx xx xx xx xx xx

I can program it in C# so it responds faster!

What is a positive response for the same vin accepted?
