Brake pressure value for brake light activation?

ADU
1

hey

can i use brake pressure value (analog to ADU), to activate brake light (via PMU).

ex. via can, or an aux from ADU to PMU ?

the main reason would be saving a brakelight switch, plumbing and wiring.

You can wire it in the ECU. So the PMU can read the accordingly AIN in. Then you write a Function

in the PMU.

Yes, via can. Create function in adu and send over can or send pressure value over can and use function in pmu.

Wire the Sensor in the ECU. The PMU cant red brak.press from bus.But it can read the AIN Voltage from the corresponding ECU input. so u can write a Funktion in the PMU that works with the Outputs. And if you need, the ADU can read ecu.brakePress from ECU.
