KLine code may be in there but Volvo flash these controller with a SBL over CAN-BUS.
They reside on the low-speed, 125KBPS network.
Can you find any 'maps' per say?

A quick scan and the K-line stuff used in the VAG Gen1 controller is not there. The only K-line stuff appears to be a small KWP1281 function, just to read info and call a function which doesn't appear to be present, possible development stuff, not implemented in the production controllers.
If you're looking for maps, the data section is contained in the "DEM EXE.vbf-block2" file in the rar you posted. Disassembly will be needed to figure out the particular characteristics, etc., unless you have an a2l, etc. file.

Cool, I know what I'll be trying to-do tonight...
IDA isn't easy though, any chance you can share a file correctly setup to give me a chance?

Here's a bin that I believe is setup in the correct order, haven't created an ida file though.

Anyone got any further with this. I'd really like to change my torque split.

I've got my hands on one of these. Does anyone know the pinout for the 8 pin connector? I assume kline will be there. |

Haldex Pinouts:
T8 - Socket between car and control unit
T8/1, Red = Ign.
T8/2, Black = Gnd.
T8/3, White = BLS (brake light switch)
T8/4, Blue = HBLS (hand brake light switch)
T8/5, Brown = K-line (diagnostics)
T8/7, Blue/Grey = CAN low
T8/8, Blue/Orange = CAN high
T2 - Socket between control unit and feeder pump(pwm switched voltage)
T2/1, Yellow = Pump 1
T2/2, Yellow/Black = Pump 2

Threadsurrection...
Was going through some of my car stuff today and found two Haldex controllers. One has an internal memory fault, the other is a working backup for the one in my TT.
I'm going to tear into the bad one this afternoon a little and monkey with it.
If any of the highly experienced members here want me to send them the bad unit to research and see if we cant get the eeprom and flash read, please contact me. I'm interested in getting this undertaking back off the ground and add a chapter to the DIY tuning history books.

Hey guys
If unitedmotorsport sorted this out then we have to get it working too!!
As far as I know customers are able to flash the haldex unit at home with their loaner tool.that means the customer plugs in the cable to the obd port and flash the file via obd
I know sounds easy so it has to be for customer that doesn't have a clue about tuning.has to be easy.
Back to the bootmode stuff.since most guys in this thread said there is an cr167 infineon like ecu in the haldex unit
Didn't anyone tried to connect to the unit with minimon??
The tool was made for this..
Let's get this back....
