Any idea what tests I could perform on the display unit itself? If I measure resistance between pin 5 and 2 it's about 68k~Ω.
OMG hahaha that's so stupid of me.
Oh okay that makes sense. I've just measured the voltage. I haven't tried turning them on with a seperate supply or ground.

Also yes your wiring diagram is perfect. It's exactly how you've mentioned it. I just don't know why pins 6,7,8 have 12v with just ignition and...
Pin 10 of the display connector is empty. According to the 355 manual it should be the reverse input. I just saw your updated wiring diagram and...
When I turn the ignition on I get 9-10 volts on pin5 of the display unit connector. Also I made a mistake previously where I said I get continuity...
Yeah that's because the connector lock is in between the top row.
I hope the numbers are visible. I don't know if the image quality reduces once sent

Yeah removing the pins is a little drastic but I don't have a lot of options. No there is not continuity between any pins with both TCU and...
The first picture is the picture of the display unit connector. There are no pin numbers on neither the display unit or connector. Pin1 starts...
In the manual it states that the warning light switching on request is sent to the TCU from the display unit. So maybe the pins 6,7,8 are the ones...
Also with the gear display connector disconnected there is voltage in pins 2,6,7,8. I know that 2 is the 12v pin. 6,7,8 are the friction, auto and...
Okay so small update. I tried to do the the thing taz mentioned. Start the car and hold down auto with all doors closed. But no response from the...
Thank you for the response. But unfortunately in my case it's not that simple. I have the SD1 scan tool and it shows a control display error. Also...
Ye Yeah it is a 97. Thanks for that I didn't notice my mistake.
I Is there a particular amount of time I should hold the auto button down?
Sure will do. It's one of the 3 relays that sit next to the TCU right? I know that one of them is for the TCU, another is for the F1 pump but I...
