Code U0167 Dodge Description

The vehicle's primary communication network, the Controller Area Network (CAN) data bus system, facilitates information sharing among all connected electronic modules. Both high-speed (CAN C, 500K) and low-speed (CAN IHS, 125K) buses maintain a similar message structure, allowing the Totally Integrated Power Module/Central Gateway (TIPM or TIPMCGW) to process and transfer messages between them. The TIPM also records Diagnostic Trouble Codes (DTCs) for specific network issues.

Modules communicate via these buses using serial transmission of encoded data messages, where data bits are sent sequentially over a single line. Each module can send and receive data simultaneously, with messages comprised of voltage differentials between two bus circuits. Message integrity is critical; corruption of even a single bit can corrupt the entire message, which includes a Cyclic Redundancy Check (CRC) to ensure accuracy. Faulty messages are identified when they conflict with the CRC, indicating communication failure. Diagnosis with a lab scope might show bus data activity even when actual communication is absent, particularly in high-speed buses prone to opens and terminal push outs.

Open circuits or terminal push outs can isolate modules, disrupting communication. An isolated module can send and receive its own messages but fails to interact with others due to the lack of functional arbitration, altering bus voltage and corrupting ongoing communications. The CAN bus modules connect via a twisted pair of wires, shielding against electromagnetic interference and ensuring the integrity of the low voltage signals. During operation, one wire carries a higher voltage (CAN High) and the other a lower voltage (CAN Low), maintaining balanced signal transmission.
