Unlocking The Mystery: U1550 Fault Code Explained
The u1550 fault code is related to the Local Interconnect Network (LIN) Bus.
It occurs when the Body Control Module (BCM) loses communication with the Driver Seat Heating and Cooling 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 a master control module and other LIN devices within a subsystem.
When the BCM sets the no communication code against the non-communicating LIN device, the u1550 code is triggered.
FAQ
