Hex codes??
Hi guys..
I got a ELM 327 with bluetooth, and I use Torque and ELM terminal mode.
When I use Torque I can only read engine codes.
If you what chassis and body codes you got to use ELM terminal app.
The veichle run a SAE J1850 VPW protocoll.
The problem is that I don't know how to read the hex codes and translate it into something that I understand?
Took some screendumps while trying to figure it out.
The one above, is a codes I can't figure out.
I read somewhere that 10 is engine, and 40 is bodycodes, but the rest I don't get.
So if anyone could help me with this, I pretty sure that I know the issues but need someone to veryfy that for me.
Regards Michael

I'm not sure that I'm doing this right?
Scanned again and got this...
If I take the second code and translate it.
6C F1 40 59 A6 00 13 BA
A600= B2600? Is this correct? Daytime Running Lamp Control Circuit (BCM)
4 = C0
5 = C1
6 = C2
8 = B0
9 = B1
A = B2
D = U1
E = U2
If I get this right the following should be
6C F1 40 59 90 17 11 E0
9017 = B1017 Passenger Deployment Loop Open
6C F1 40 59 B8 08 11 CB
6C F1 40 59 B8 09 11 87
But what does these two codes do?
B8? How du you make a code out that?
6C F1 40 59 00 00 13 4F
Is this a type of "end of message"?

Finally i figured this one out
First you got to turn on all headers by sending command
AT h1
Then you got to tell the ELM witch computer you
wish to talk to... In my case 58 (airbag module)
So you send command
AT SH 6C 58 F1
When you sent this you will recive OK
Next line to sent is one of the following
19 c2 ff 00 with this you will get current codes
19 d2 ff 00 with this you will current and pending codes (I used this)
Got this code in return
6C F1 58 59 81 00 13 99
AA BB CC DD EF GH IJ KL
AA = Node to node
BB = Adress to scanner you're using
CC= Witch part the code is located in. Engine,trans,abs,airbag m.m.
DD= This I'm not sure about
E = First part of the code
F = Second part of the code
G = Third part of the code
H = Fourth part of the code
IJ= Status of the code 00=god 11=and up eq.fault
KL= Checksum of the code just ignore this one
4 = C0
5 = C1
6 = C2
8 = B0
9 = B1
A = B2
D = U1
E = U2
So my code to translate EFGH in the message above.
81 00 = B0100 You replace number 8 with B0 in my case.
So my code would be Bodycode B0100=Electronic front end sensor 1 performance
You will also get a code that says 00 00 on the next line.
It means something like end of message.
Below a good site with lots of obd codes
OBD II Body Trouble Code Chart
10 = ecm (main engine brain)
28 = abs
40 = bcm (body control module)
58 = airbag module
60 = IPC (instument panel cluster)
62 = hud
80 = radio
c0 = immobilizer
The letters CC in the code above tells you witch part the codes are from or
you wish to talk when you're sending you're command.
Sometimes you'll get a lot of codes so the easy way is to adress each part
at a time and ask for trouble codes.
There should be one for CC code for the transmission also, but haven't figured that one out yet. Anybody knows feel free to complete this list.
If you turn on all headers and send the command 19 d2 ff 00, it's not always
all parts will respond. For an example the BCM and airbag module won't respond.
When you send the command 14, you will erase all codes!!
When I did this I used ELM 327 bluetooth and my phone with the app ELM 327.
If someone sees anything that's misspelled or that doesn't work feel free to let me know.
So I got a new front sensor and problem solved... didn't need to erase the codes since
the airbag module does a self test on start up.
Hope this helps someone...

Hi SnIpeR...
Try using the Torque app. there are two versions of this one free and one you have to pay for...
A Screenshot from my phone, I'm using an Z1 Xperia
Link to app so you know witch on it is.

Hope this helps??

Sorry Sniper ...
Are you having trouble pairing them togheter??
When you plugg in the elm you have to pair them togheter
It could come up a password request. There are three diffrent ones
depending on the model youre using..
Passwords 0000 or 1234 or 6789 these are the ones I'm aware of..
A little video clip check out in the video about 5min in to it.
He explains how to pair it..
Hope i helps
It should work just fine but I've read somewhere about some versions of the ELM 327 that
are bogus. And don't seem to work at all.... Not sure witch ones.
I been using this on a 1997 Blazer 4.3,2005 GMC Savana 5.3 and on a 1998 Volvo S80 T6

I have vehicles following ISO 15765-4 (CAN 11/500). I bought an ELM 327 to find Body and Chassis fault codes.
I tried using the above commands, but with no success.
Even tweaked a few commands like AT SH 7E8 instead of AT SH 6C 10 F1, because the response header for the PIDS (like 0101, 0100 etc) is 7E8. Tried AT SH 7E8 10 F1, but didn't work.
None of the method works. Am I missing something? Will this method not work for the above protocols?
How can I retrieve Body and Chassis fault codes for the above protocol? Any help.
P.S. Also that mode 13 gives 'NO DATA' hence the 'Buffer full' problem is still there when I run ATMA command.

Elm adapters.
I paid for two ELM adapters that did not work correctly. They would set off the stabilization warning. They also could not read the transmission temp. I finally found one that works without bugs. After my third try this one works.
