355 F355 not shifting

With everything connected and assume the car is fully fitted and everything is in its place, I turn on the ignition and get the 3 or 4 buzzer beeps from the buzzer beside the fuse box, the display during this time lights up all pixels and when the buzzer stops the 2 dashes are displayed on the display along with the F1 gearbox warning light on. The low friction and auto gearbox warning lights come up initially and turn off (like almost all cars where the lights come up with ignition on and then turn off). The red fault light never flashes. It turns on with ignition and remains on.

 

Yes pump kicks in and out and pressures are all good.

 

No problem. Mr.eric has done the same test and measured what was needed. He was getting the same values I did.

 

This isnt a USA or GB model. It's a europe model. and also yes I have checked all 3 relays that sit beside the TCU.

 

Yes and the reason its staying lit is because it has a display control error stating short circuit to VBAT which is happening on pin 5. But we have come closer to a better answer on this thread that the 10v on that pin5 of the display unit is normal and the TCU is the real devil that isn't pulsing the voltage on that pin for some reason and that is why it is throwing an error stating short circuit. Its basically stabbing itself in its own leg and then crying out for help.

 

Honestly I don't know about it flashing when you initially turn it on because i have had this fault for so long I dont even remember if it does that but I'm sure you're right. Either way right now it stays on becuase of the short circuit to VBAT error.

 

I was reading through that thread and found this. Since this is the case maybe my software is faulty somehow and that is why the TCU isnt communicating?

 

No I have not done an engine out recently. After my previous engine out the car ran fine. The car had been sitting for well over a year after which this problem has started.

 

Yes my brake lights work.

 

I don't think the 97' came with and OBD socket. If you mean the individual sockets for various control modules then I have checked with them unplugged as well.

 

No thats not the case with this. I think OBD only came out with the 99 model I'm not sure. It is definitely not there in my car because I have pulled out the dashboard and havent found anything

 

I will definitely check this out today. Its been more than a day since I have turned on the ignition since yesterday was sunday.

 

Yes they are. I didn't know that only US models came with this. Also have a look at post #114. I quoted wolfgang from the other thread. Might be helpful. Thank you.

 

Would be so helpful if I could get another TCU to just check this and verify if that's the problem before purchasing a new or used one. New ones are going for about 12k£.
