The Electronic Brake Control Module (EBCM) activates the other modules connected to the CAN serial data circuits by applying voltage when the ignition key is in ACC, ON or START. The EBCM, Multi-axis Acceleration Sensor, and the Steering Wheel Angle Sensor are the only module and sensors connected to the CAN bus serial data circuits. For more information on CAN bus serial data refer to Data Link Communications Description and Operation .
