360 F1 won’t shift passed 2nd

John,
You are 100% correct...!
Without a clear understanding how a system works and diagnostic equipment that can identify a fault with parameter monitoring you are pretty much wasting your time. I have been in the automotive field my entire career I've never repaired a vehicle without fully understanding the symptom then a proper diagnoses.
Although brand new to Ferrari I'm learning everyday....this F1 system is unique and one hell of a design.....from my perspective it is a external valve body controlling a mechanical shifter....
I do admire the willingness on this forum to help others..

I commend you for your efforts and attention to focus on the task at hand, Being new to the Ferrari technical world I am slowly building my knowledge everyday at the same time aquireing my needed tools, workshop manual, electrical manual and a scanner..
Your reoccurring fault codes are clear indications where to focus..attention master Ferrari techs please chime in and help this Fchat brother..
I'll keep watching this thread...

Sounds like there's something bogging down the CAN bus. You might want to check the two termination resistors along the bus. Have you tried disconnecting the TCU and rescan with tool? Just to see whether the CAN bus error comes back or not.

 

The termination resistors are at: 22B and 18G - Resistance value should be 120/ohms
You might also want to check that the joint connectors 10G, 17G, 14G, 15G and 12P are tight. The CAN bus wires are White/Green pair. These are off the wiring diagrams for a Spider, but should be very close for a coupe as well. Also take a look at the connectors in the back of the instrumentation cluster. There should be a CAN bus pair behind that as well.

That’s unlikely to happen and shouldn’t be expected. For us it’s inquisitiveness for them it’s their livelihood. Most have given up posting on here because of some comments received.....a shame but why give time and hard earned knowledge for free then get flamed
It’s a gap in FChat but maybe there is space for a professional support option that you pay for. Or maybe not!

The OP really needs to get a good F1 technician. Braden were mentioned above but there must be others and take the car in. They may let you work alongside them or at least explain the issue and resolution.
The system is relatively simple despite what you may be led to believe, the real clever bit is inside the TCU.

 

Totally understood...!
Expected absolutely not, nice gesture to help out someone in need why not...?
There is nothing mysterious about a can bus...wiring diagram/ electrical specification [terminating resistance] and DVOM one should be able to sort out...
Speaking of terminating resistance typically it is 120 ohms within the designated CU...when its partnering CU is in the circuit it and all is well the wiring it should measure around 60ohms....
I'm new to Ferrari but not new to the technical side of the automotive world I've learned allot from this forum and love the passion we have for our Ferrari's.
I think you may be onto something with a special site within this forum to assist with the DIY....just a thought..?

John,

They’re not all the same. I’m in the UK and there are a few I’d highly recommend in a heartbeat. The US can’t be any different.
If you read my posts on other threads I’m as inquisitive as anyone, particularly on the F1 system so good luck with your endeavours and keep posting.

I am not overly familiar as to the electrical workings of the F1 system, but has a bad clutch sensor been considered?

Maybe disconnect it and then run the scans again as you have to see if the errors appear again?

Just a thought

 

You mentioned that you get a brake switch error message and since touching the brake is part of the F1 system maybe the error is coming from something external that affects the entire system.

That's why I suggested checking the clutch sensor.

Could be the clutch sensor is bad and causing the error messages and lacking of progressing to higher gears.

It just seems that you are going through a huge procedure in your system testing, and it might be a simpler issue than it appears created by a failed or failing component.

 

I was not suggesting to disconnect the TCU.

I was getting after the issue of a sensor since the wiring in the car had not changed, and you spent time tracing that.

It made sense that it was something of a sensor that was causing codes.

Bottom line is that you are back to a functional shift pattern.

 

Just a hunch but at 32% your clutch sensor and ecu are saying just replace the clutch and my heat exchanger went at 87000 Klms
Took ages to clean it all out coolant in gearbox ect once done we had a run for 900klms in one day got home more sludge in coolant reservoir replaced coolant transmission oil again now clear but gears grumble in reverse specially with steering and 3/4 synchro click clack but so far 10,000 so good ,cars done 110000 klms runs like a Swiss clock really good motors, strong gearbox but they take a pounding sorry to hear your having a hard time but once sorted they are a joy good luck Adrian Oz

So based on. Your other post was the actuator the issue ?

I tried and go back and see which sensor .. but for the benefit for future reference which sensor did you change .. where did you buy and how much

Trying to help the society here for the future
