Hello,

So gf had issues on and off, now its all the time, it wont shift, abs light flashes, esp on dash, you name it! Scanner shows multiple can bus faults.
Anyway, I played with some grounds and it fixed it for a bit, now its back, so anyone have a good source of CAN terminating resistors or any good write ups on every ground these things have etc?
The thing has 44 total faults, so I'm thinking its CAN BUS term resistor but the OBD2 connector has a bunch of different connections different than what i'm used to with American cars and i cant get a 60 ohm or 120 ohm to read anywhere, any info is great, thanks!

The only time i had multiple canbus issues was when the key had dirt inside it!
There is a red lens on the tip of the key, if that gets any dirt inside it, it can cause multiple CAN errors..

interesting,
i'll check into that, but i did find that
pin 16 on the obd2 connector has 1-3k ohms when i touch chassis ground which must be a canbus short somewhere

is there a damn obd2 pinout anywhere for this car? literally doesn't follow any obd2 connector i have found

UPDATE:
I started simple, I cleaned all the easy to access grounds in the engine bay, brap brap with my electric die grinder, polished them up nicely.
I used sand paper to access the base of the studs until they were shinny, the one on LH side near the frame + headlight assembly was very dirty.
Reset all codes, fired it up, took it for a test drive, shifted fine.
