Brake Pedal Switch

WARNING: This page is about a different car, the 2018 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
G11308574

The brake pedal switch is mounted on the bracket for the brake pedal. The brake pedal switch is connected to the vehicle harness using a four-pin multiplug.

When the brake pedal is pressed, the switch contacts close. This sends a hardwired signal to the Powertrain Control Module (PCM). A brake pedal switch status message is then sent from the PCM to the Anti-lock Brake System (ABS) control module on the FlexRay bus. The ABS control module can then control braking force accordingly in conjunction with the Hydraulic Control Unit (HCU).
