Cmercon:

What operating system and what version of the Vol-Fcr software are you using?

This seemed to work, but there was no luck communicating with "immobilizer" and "instruments": Plug in the USB-type cable, let Windows 7 "automatically" find the drivers, set port to com1, other advanced port settings set to default, connect cable to OBD-ii port, key at position II, then attempt communication with a module via Vol-FCR.

If you can see the correct "immobilizer" and "(combined)instruments" output, what are your settings?

If using a VAG-COM 409.1 OBDII to RS232 cable make sure that the port is set to COM1.

If using a VAG-COM 409.1 OBDII to USB cable, it is necessary to install the appropriate drivers. Most of these cables use the same FTDI chip and the drivers can be located on this page (link).

NOTE
After the VCP drivers are installed and the cable connected, make sure the port is set up correctly in Control Panel - Device Manager - (look under Com Ports).

Under Properties - Port Settings set the following:
Bits per second: 9600
Data Bits 8
Parity None
Stop Bits 1
Flow Control None

Then Under Port Settings - Advanced set the following:
COM Port number: COM1
Receive (Bytes) 64
Transmit (Bytes 64
Latency Timer (msec) 3
Minimum Read timeout 100
Minimum Write Time out 100

SlapShot -

Thanks. Those settings were tried, but still no luck. The VCP (virtual com port) drivers are current.

For the immobilizer there is a time-out error. It looks like communication never happens.
For instruments, "comms message" shows comms is established, and for a couple of seconds "comms status" shows "ok".
Shortly afterward (whether or not Read DTC is selected), module ID shows "invalid data".

The cable is a USB K-K-L 409 Vag-Com. Does a "K-L" type cable work where "K-K-L" would not?

Try turning the baud rate lower than 9600 and the latency timer less than 3. I have one of those cheap china blue cables from eBay and everything works. Not saying my settings are ideal but they work on all the cars I've tried it on. Maybe you've got a wonky wiring issue or ground?

Does everything work for you with both Windows 7 and XP? Does your cable work with both 1.3 and 1.7 versions of Vol-FCR?

I'm going to try the settings you suggested.

version 1.7 (not 1.3) does show the "instruments" module - same port settings. Still nothing for the immobilizer, though.

Works fine with Windows 7 (32 or 64 bit) and Windows XP. I'm using Vol-FCR 1.3.06...which can be "acquired" online. Where did you find 1.7 / is it a demo?

Yep...the 1.7 I have is the demo version. I'm using Windows 7 64 bit (not with XP mode).
For accessing the power seat modules and instruments sometimes it takes several tries to get communications established.

I tried those settings...still no dice even with antivirus off. But it looks like for the "instruments" module, v1.3 software might be the problem (since the demo 1.7 at least shows comms where 1.3 shows invalid data).

Maybe the cable is part of the problem. I had codes read and remotes programmed at one time at a dealership. They didn't mention anything about inaccessible modules.
There is communication with the "lock and alarm" module.

Gonna zombie this thread, hopefully you guys can help. Car is a 96 850 T5 Wagon. Using my laptop (Win 7) and my Vag cable along with Vol Fcr I can't read the ECU. I CAN read the trans, instruments and a few other things. Just not the Mot 4.4. The fact I can read the other things makes me think its pbviously not the cable or fuse issues. Checked fuses anyway. Also tried changing Com settings like above. It will not establish Comms with the Mot 4.4... Only the other things..

Ideas? I have a CEL that I need gone/fixed asap so I can pass inspection..

Use a difference scanner then... If you still can't pull codes then you have a tranny code stored on the ECU that can't clear unless you clear the TCU..

The 1996 850 Turbo uses M4.3 for the stock/factory Engine Control Unit. Unless you are running an ARD tune that is converted to M4.4, or at some point someone dropped in a M4.4 ecu from a S,V,C, or XC 70 you will have Bosch Motronic 4.3 ECU, which is not readable with VOL-FCR.

No.

With VOL-FCR 1.3 You CAN read OBDII ABS CODES and RESET SERVICE LIGHT on a 96 850 w/ a working OBDII port. You cannot use VOL-FCR to clear engine codes, and half the other features of 1.3 will suggest you to use a pushbutton/LED setup as if it was OBDI. That's about all Vol-FCR 1.3 can do with ME4.3

You need the proper cord, and i don't remember what the right chip is...there is a bunch of threads on it, but iirc it was just a general VAG-COM one. The virtual com port is fine, you need the FTDI driver if your using the USB cord version. I've always used XP, so i can't comment on if the drivers work in Vista or 7...

I have no clue on how Vol-FCR 1.7 works.

Worst case scenario, get an LED, resistor and switch and viola :P

To clairify, I was not saying you cannot read any codes, just the ECU. In VOL-FCR the button is yellow and will tell you how to make the switch. The issue is only with M4.3, as M4.4 is fine. The poster was say they could not read the M4.4 ECU codes on their 96 850 Turbo; 96 850 Turbos used M4.3

As well, I have not yet used VOL-FCR1.7 so I cannot say if M4.3 readability has changed.

I've used RS232 serial cables and the FTDI USB VAG-COM cables, and the M4.3 readability remains the same, version 1.3 of VOL-FCR. I've used VOL-FCR in XP, Vista, and 7 without issue and I've used it on my 96 850R and 98 S70.

Gotcha :lol: Just a misunderstanding on my part then.

Yea, the whole reading Engine codes through VOL-FCR is a no go like you said, but, there are many other programs out there which you could use to do that. I only read his initial post which seemed to say ABS, and i took it from there...but you are absolutely right. I love VOL-FCR for what it is, and if 1.7 read all the codes i would purchase it for simplicity. Otherwise...LEDs or VST(good luck buying one)

The cable I am using IS a Vag Com one, that I use on my Audi. And the cable is fine, and its drivers, as it WILL allow Vol Fcr to access my TCU and a few other things in there.

But on a spot of good news, Autozone was able to read my codes. So the port is fine too. Just can't seem to jive with Vol Fcr. Maybe it is because its a Mot 4.3? Either way, my issue is fortunately just a TPS. Part is coming in today.

Fault codes on M4.3 can be read by Motronicsuite, Brick-Diag, KWP71Diag and some other prototypes with a VAG cable.
