System Operation: ECD

The braking operation is controlled by the ABS module, in response to a request from the EPB module on the high speed CAN bus. The ABS module monitors the deceleration rate using the wheel speed sensor signals, and adjusts the hydraulic pressure to the brakes as necessary to achieve the required deceleration. All of the anti-lock control - traction control system brake modes remain enabled. As the vehicle comes to a halt, the hydraulic pressure is reduced to zero and the EPB module applies the parking brake with the EPB actuators.
