Electric Park Brake (EPB) Switch

The EPB switch is located adjacent to the TCS knob and mounted in the floor console. The EPB switch and the TCS are supplied as an assembly, and cannot be replaced individually.

The switch has three states:

• Neutral: The central default position. The switch returns to this position regardless of parking brake status
• Apply: When the switch is pulled up to apply the parking brake
• Release: When the switch is pushed down to release the parking brake.

The EPB switch contains a pair of micro-switches for both the apply and release actions. The EPBCM provides an individual hardwired electrical feed to each of the four micro-switches plus a single ground connection, allowing it to constantly monitor switch status.
