CAN Interface

The Bosch DSC III 5.7 is connected to the CAN bus for communication with the AGS, DME control module, Steering Angle Sensor and the Instrument Cluster.

Using the CAN bus, all of the connected modules can receive information or send commands.

Communication with the DSC III 5.7 includes:

• DME  - The DME sends current engine torque. DSC commands the DME to reduce (ASC/DSC) or raise (MSR) engine torque.
• AGS  - The DSC commands the AGS to suppress shifts during regulation.
• LEW  - The DSC receives steering angle information.
• KOMBI  - The DSC commands the instrument cluster to activate or deactivate the warning lamps.
• All four wheels speed signals are sent over the CAN bus for use by other modules.
