U155D: Unraveling The Mystery Of Lost Communication With Instrument Panel Cluster
The u155d fault code is related to the Local Interconnect Network (LIN) Bus. It occurs when the Body Control Module (BCM) loses communication with the Right Rear Seat HeatingVentingCooling Switch on the LIN Bus. This happens when the supervised periodic message from the switch to the BCM is not received.
The LIN Bus is a single wire with a transmission rate of 10.417 Kbits used for serial data communication between the master control module and other LIN devices within a subsystem. When communication is lost between any of the LIN devices, the master control module sets a no communication code against the non-communicating device, resulting in the u155d fault code.
