Multiplex Integrated Control System Description - Control/Function
Overview
The body control module is one of the F-CAN and the B-CAN components. The body control module controls many systems related to the body controller area and security system, and also works as a gateway to diagnose the other B-CAN connected ECUs with the HDS. Self-Diagnostic Function
The body control module provides the self-diagnostic function for checking the communication and input systems. Communication Check (Test Mode 1):
When the B-CAN BUS or the connection to the gauge control module is disconnected, an error code is shown with the number of blinks of the individual map light. Switch Input Check (Test Mode 2):
When the input of a switch or a sensor to the body control module has changed, diagnosis of the input system can be performed on the basis of the individual map light flashing count. HDS Diagnostics
The HDS connects to the data link connector (DLC) to communicate with the vehicle's control units. This allows the HDS to retrieve DTCs, diagnostic data, or transmit forced commands during output function tests. Customize Memory Function
The body control module has a feature that allows the settings of certain outputs to be customized to user preferences with the HDS. |
