TBC Module Wake Up

WARNING: This page is about a different variant/trim than selected.

With a trailer connected to the vehicle, the TBC module will remain active while the ignition key is in the ON position to monitor the vehicle and trailer brake systems. Without a trailer connected to the vehicle, the TBC module will enter a "sleep mode" but will continue to send a PWM voltage signal to the trailer tow connector every 4 seconds to detect when a trailer is connected.

When the ignition key is in the ON position and the module is in sleep mode, pressing a gain button or sliding the manual switch will cause the module to "wake up". If a trailer is not connected to the vehicle, the message center display should prove out for 3 seconds and then display TRAILER DISCONNECTED. If a trailer is connected to the vehicle, the display should prove out for 3 seconds and then display TRAILER CONNECTED.
