The trailer connectivity status, gain setting and relative trailer braking power during a braking event are provided to the driver through the LED

The brake pressure transducer is part of the master cylinder assembly.

brake pressure transducer must also be installed and the instrument cluster must be reconfigured to communicate with the TBC module.
