Hi,
I have a Maserati Trofeo racecar in GT4 Spec. I've been experiencing a strange issue with the gearbox warning light during my last outing at Spa-Francorchamps. I've conducted extensive diagnostics, and here's what I've found:
This is a factory racecar, not a converted streetcar, so while some parts are standard, others are unique to the racecar.

I used the diagnostics tool that came with the car, and it reads the "brake switch error code", as described several times on this forum. But this car has not the ususal brakeswitch but a very basic pressure activate NO switc, connected directly to the brake pressure line. example below:

Key details about the car's braking system:
Here are my findings from further testing at home:
The most intriguing thing here is the exact 10 seconds it takes every time before the error starts after releasing the pedal. So, I think there must be some kind of checking procedure the TCU is doing that takes exactly 10 seconds.
Can anybody provide insight into what could be the reason? What is measured or checked by the TCU? What takes 10 seconds?

Key details about the car's braking system:
- No ABS or ESP
- No power-assisted brakes
- Factory-fitted Alcon pedalbox
Here are my findings from further testing at home:
- The warning light comes on EXACTLY 10 seconds after releasing the brake pedal.
- The warning light stays on.
- When the brake pedal is pushed, the light goes out after approximately 0.5 seconds.
- Release the pedal, and 10 seconds later, the light comes on again and stays on.
