B2200 ACURA, HONDA: COMMUNICATION BUS LINE ERROR
The B-CAN (Body Controller Area Network) and F-CAN (Fast Controller Area Network) networks share information between various ECU (Electronic Control Unit). The B-CAN communication moves at a speed of 33.33kbps for comfort-related items and other functions. The F-CAN information moves at a faster rate (500 kbps) for real-time functions such as emissions and fuel data. In order for the two systems to share information, the Meter Control Module translates the information between the two networks, it is a process known as a gateway.
The MICU (Multiplex Integrated Control Unit) has several activations and sleep functions that reduce battery consumption when the power switch is set to 0 or LOCK. In case the MICU detects a communication bus line error with other control units, the diagnostic code B2200 OBDII will be set.
The B2200 OBD2 fault code is set for one of the following reasons:
