Theory Of Operation

WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

The brake switch signal must be active before the shift lever can be moved out of the park position. When the brake pedal is applied, the Body Control Module (BCM) receives a hardwired signal from the Anti-lock Brake System (ABS) Module. The BCM then provides battery voltage to the Transmission Shifter to activate the Brake Transmission Shift Interlock (BTSI) solenoid.
