Saab Turbo Club of Norway

This year i bought Lawicel Canusb dongle.
Started to do connections between T7suite and trionic in car.
At first tried to hook on I-bus. Everythung works fine. Connection was established in 2-3 try time.
Then i tried to connect dongle on P-bus...
From the beginning it was so that it does not connect via P-bus trionic to t7suite with dongle using a simple twin wire about 1 meter in length.
Now once again I reached my hands to make a difference in the current situation. shortened the lead up to 50cm - nothing has changed,
duct tape was unwound in front of trionik shoe where I was soldered the wires, and tried to hook with only 5cm wire / still got nothing.
(when at first i start the suite when click on the "Connect ECU" button dongle blinks Green for 2 seconds then goes off and i see"Unable to connect" in T7suite statusbar. When i reconnect usb to PC repeating the procedure of connection (without restarting the suite) all next times dongle lights Red and then freezes t7suite)
When i connecting via the I-bus - i have access after 1-2 attempts of reconnecting usb cable.

What im thinking is try to test someones Lawicel Canusb adapter on my vehicles P-bus...

Will be happy to see the answer in PM or any suggestions at this thread.

ps: tried without 100 Ohm resister in dongle in between can-H and can-L - any attempt looks the same like with resister soldered.

You dont need ground. You dont need resistor. Tried to swap the wires? Is your car an automatic?

I dont use ground and as i posted before i tried without resistor too.
Been tried swapping a wires when connecting with 5cm cable then was noresults

Car with manual gearbox.
..I thought maybe some dramatic hardware changes in canusb dongle was done by manufacturer......
ps: forgot to say
When was hooking on desktop at home everything worked fine, and im downloaded bins and reflashed ecu couple of times.

Check battery voltage.

Voltage floating arround 14-14.2 volts according to sid symbol (engine started)

Intresting.. today one attempt to connect P-bus was good but when i opened realtime panel in t7suite i see that all "gauges" often freezes up to 2 sec.
Then i manage try to download bin from ecu - but suite freezes again.. strange

Check voltage with ign. on (not running).
place the light switch between 2 of the break points(all light shuts off ).

using the correct drivers/reinstall?

Try using an other laptop?

turn off wifi.

[quote="Pål N526"][/quote]
Voltage 12.2 stable @ignition on (engine, acc, music, rear gear and all the lights OFF, doors closed)

other will try later at this uke

i even forgot what im been done wrong))
Thanx and greetings to all ya saabguyz i Norge!!!
