Hi

I have a perfectly working car but when i try to connect techstream which is working on 2005 yaris, i am trying to connect on 2011 NSP120 1NRFE I cant get techstream to identify the ecu, it use to be connected. All i can rememeber is i have installed aftermarket android car play but no error on dashboard.

I am driving nuts here dont know car is driving fine no codes. but i cant communicate CAN H CAN L.

I did the dead test CAN H CAN L 60 OHM, voltages are healty on CAN H CAN L

any help please would be highly sppreciated.
