Finally i made a picture, how to read the haldex controller via bootmode and kline (yes, i love paint Cool

)

I know there are more versions of this controller in the field, please send me an hires picture and i will
make the modifications necessary to connect via bootmode.

I hope my picture is not too confusing Cheesy

wow thats make a sense
do you have a pinout for that +12v/kline/gnd port?
which software you are using?
is it possible to write flash back?

Incredible. Thank you!
Though more than expected that needs to be connected and therefore much more difficult to achieve. Do you have a live picture of how you did it?

Is there no need to control direction of kline? In flash code it looks like P2_14 must be set or cleared to controle receive or transmit.
Or is that what you've somehow done with the connection of mcu and transciever?

use the original power plug from the haldex controller. (you need the capacitor in the plug)

black 8 pin connector from haldex:

Pin 1 = +12V
Pin 2 = Ground
Pin 5 = K-Line

i use an self written application for boot mode and modified flash drivers.
but minimon should work too, but i havent tried.

yes, possible to flash back - tried many times Grin

without Haldex cable

I've only done vcds through these pins and need to test to attach a correct capacitor.

no problem, i am happy if i can help

and i think nefmoto is a nice community.

i was most surprised about the pol0.4 connection, why its on the header.

i can make a picture in action, i soldered wires on the hybrid - a bit fuzzy, but its possible.
later i used test pins (spring loaded needles) to connect.

hmm, could be - i havent analysed this part of software yet.
the connection is there because i haven't found any route between asc0.txd and the input of the k-line transceiver.

you need only some µF. about 100µF to 470µF should do.

ok, well then I don't even have to look for the cable. I've got many standard caps like that.

I find it a bit confusing that they've made the P0L.4 available at connector if it's not supposed to be possible to work without connections directly at circuit board.
(suprised just like you :-) )

Well there is connection since all communication go through S0TBUF and S0RBUF (hance ASC0) but they also have the P2_14 connected to the transciever to control in/out from the transciever.

They do a bclr P2_14 before every load of TBUF and a bset p2_14 directly after Transmit interrupt to be ready to receive again.

Haha, yes txd could ofcourse control the CS :-)

The problem is that I don't know for sure if receive status of transciever is default. It probably is and then it is possible to inject the 32bit load code at correct time after reset without boot mode confirmation sent from ecu. I have modified the minimonK code to control P2_14 when executed.

Yes, default is receive - confirmed.

would be good - so we only need to figure out how to disable the reset watchdog
