U11B9: Understanding The Mysterious Brake Booster Pressure Sensor!
The Controller Area Network (CAN) data bus system allows electronic modules to share information with each other. The Body Control ModuleCentral GateWay (BCM or BCMCGW) processes and transfers messages between the CAN buses. The Telematics Gateway (TGW) Module transfers messages between the CAN IHS (125K) Bus and the CAN Audio and Telematics (AT) Bus.
The BCM and TGW store Diagnostic Trouble Codes (DTCs) for certain bus network faults. Modules transmit and receive messages over the CAN bus using serial transmission of encoded data messages.
Each module can both send and receive serial data simultaneously.
Corruption of a single bit within a message will corrupt the entire message. Each message contains a Cyclic Redundancy Check (CRC) which specifies the message size exactly. When an open circuit or terminal push out occurs, one or more modules can become isolated from the remainder of the bus.
The isolated module will attempt to communicate, but will not be able to receive messages or determine arbitration from other modules.
The Diagnostic Trouble Code (DTC) U11B9 sets when the Bus messages are not received from the Radio Frequency (RF) Hub Module for approximately two to five seconds.
FAQ
