I'll have to check between 4 and 12. Apart from that I think we have checked everything else. All that's left is the TCU. Any idea how or if we...
Thanks for this. I read through quite a bit and he seems extremely knowledgeable.
Yeah even I didn't know whether it would be safe to do that or not so that's why I used the old display and not in the cars circuit.
No it doesn't the correct gear while doing that. Maybe the TCU is reporting the error because it's not grounding it in pulses to generate the...
I was fiddling around with my old display unit. I decided to power it on my bench with a separate battery by supplying 12v to pin 2 and ground to...
I will ha Sorry I had not checked pin 4 properly. At that time I was solely focused on pin 5,6,7,8. That was wrong on my side. Also I will have...
Sorry for the late reply. Got busy in the morning and then ferrari chat was down for sometime for me.
Is there any way I can check this in the display unit?
Could pin 4, as mentioned saying power from TCU supply relay, be another cause? I have no voltage in that pin at all. In fact is a ground line. In...
Hey @taz355 maybe you could check this out if you have the F1? Would just like to know the voltage, if any, at pin5 of the display connector.
Unfortunately no luck even after cleaning it. The display unit itself is supplying the 9-10v to pin 5 which is causing the error. Now I don't know...
The input and output pins are right beside each other. Could be that one of the output pins is somehow connected or related to pin5. Obviously...
It looks like tiny amounts of water deposits between those pins. Could be wrong.
The auto warning, low friction and gearbox fault warning lamp illuminate when I turn on the ignition. Auto and low friction turn off after a few...
So I opened up the new display as well to check it out. Found a few things that might or might not be the problem. [ATTACH] [ATTACH] [ATTACH]
With display plug disconnected and ignition on there is 12v on 6,7,8 which are the 3 warning lamps auto, low friction and gearbox. When plugged...
No the display plug is connected and ignition on. With display plug disconnected and ignition on I get continuity between pins 6,7,8 and pin 55 of...
With the ignition on I get continuity between pins 5 8 and 9. Pin 9 is the input for the rheostat.
By any chance do you have access to a 355?? So that you could just check the voltage on pin 5 of the display.
Yes I had the same fault with the old display. My old display unit had a tiny bit of corrosion on a resistor and another component. I was able to...
