I'll let you know when my ELM327 turns up. Have a number of non-D3 reasons to get it, but will be nice if it reads fault codes from the D3 and would hope it gets at least some of them! wd40 has lubrication properties similar to spit. And what's good enough for the girls......  Going, going...... Gone!

Thanks NoDo$h - I was just reading your post on the EGR thread - where did you buy it from? The guy I spoke to reckons it will work fine with all OBDII vehicles but he's trying to sell it so no surprise there I suppose. It's about £55 on their web site - seems quite reasonable.

I have the ELM327 (usb one) and have had no luck with the d3.
It will register some signals , but starting the engine to read real time monitoring will not work..
This may just be a software issue , but i have tryed numerous programs with no joy.
On a positive side , connected to the wifes mini ..it works great..reads codes and real time moitoring of all sorts of things.
I have some new software im going to be trying in the next week or so ..so i will let you know if it works any better. JAVA BLACK SE , MANUAL , PRIVACY GLASS , EBONY LEATHER , COLOUR CODED PARTS , SIDE PROTECTION TUBES , HIDDEN WINCH (12000 LBS) , 19" HSE WHEELS.

Fleabay, velly cheap. assuming Customs don't wallop a £39 charge on it, it will work out cheaper than the one you've been quoted on..... wd40 has lubrication properties similar to spit. And what's good enough for the girls...... Going, going...... Gone!

The high speed bus operates at 500KB and the medium speed at 125KB, according to the WSM. A common CAN transceiver chip is the MCP2551 and it operates at speeds up to 1MB. But the problem could be simply that the wrong pins on the diagnostic socket are being accessed, as common pins are 3 and 5 for Can-Hi and Can-Low but the D3 uses 6 and 14 for HS Can-hi and Can-low and 3 and 11 for MS an-high and Can-low.

So if the ELM 327 doesn't read anything worth reading, I'm not going to lose much if I rewire the pins on the plug to match the "unusual" socket config of the D3?
If that's the case, I owe you a stubby or two wd40 has lubrication properties similar to spit. And what's good enough for the girls...... Going, going...... Gone!

If the unit is doing its own protocol searching then it could be finding the (non-CAN) K-line first and only getting what's available on that line, not even getting around to looking for a CAN bus. The K-line on the D3 only goes to the ABS ecu rather than all ecus, although because the ABS ecu is connected to the HS CAN system, it might be able to extract codes from other ecus - but maybe not too.
One would need to be able to interrogate both the HS and MS systems to interrogate all ecus, although any ecu that provides speed-dependent functions will be on the HS bus.

I'd be very interested to hear if that works NoDo$h. If that were the case though, I'm surprised those who've already tried the ELM327 have seen any data at all. D3 TDV6 S 2005 - TorqTune, Privacy Glass, Remote FBH, 19" HSE Alloys, Boot liner, retrofit F&R PDC

You are correct about the CAN speeds and the D3 pinouts but the real obstacle is the LR software in the ECU's. I tried an OBDKey and it gave very little information. The CAN bus is in most cars since 2005 but it is the software that each maufacturer puts in that is hard to get to. You have to spend more to get a fully versatile system such as the Autologic.

The wiring in the ELM327 is different to the diagnostic socket
Diagnostic socket (pin numbers)
3 - MS CAN -H
4 - GROUND
5 - GROUND
6 - HS CAN -H
8 - TRANSMISSION CONTROL MODULE
9 - ABS MODULE
11 - MS CAN -L
14 - HS CAN -L
16 - BATTERY (FUSE 63)
ELM327 (pin numbers)
2
4
5
6
7
10
14
15
16
According to ELM spec sheet
PWM The connector must have pins 2, 4, 5, 10, and 16
VPW The connector must have pins 2, 4, 5, and 16, but not 10.
ISO The connector must have pins 4, 5, 7, and 16. Pin 15 may or may not be present.
CAN The connector must have pins 4, 5, 6, 14, and 16.
So HS CAN (high and low) can be seen ...but the MS CAN (high and low) can't.
So yes i think some moving of pins may be needed JAVA BLACK SE , MANUAL , PRIVACY GLASS , EBONY LEATHER , COLOUR CODED PARTS , SIDE PROTECTION TUBES , HIDDEN WINCH (12000 LBS) , 19" HSE WHEELS.

I agree about the different pin outs. I bought a couple of OBD2 cables so that I could swap connections around. I got them from OBD2Cables.com. The problem is still getting the data from the ECU's and making sense of it.

Also need to get the pin outs for the ELM327 ..so we know what wires to move ...
This could well be a handy tool

After having another look at the WSM, there's very little on the MS bus. The engine, transmission, ABS, steering, suspension, rear diff, EPB, SRS and adaptive lighting are all on the HS bus, so not much point in moving any ELM327 wires.
