Unlocking The Mystery Of U1549 Fault Code
The U1549 code is related to the Local Interconnect Network (LIN) Bus.
It occurs when the Body Control Module (BCM) loses communication with the Rear Wiper Motor on the LIN Bus. The LIN Bus is a single wire with a transmission rate of 10.417 Kbits.
The master control module sets a no communication code against the non-communicating LIN device.
The DTC sets when a supervised periodic message to the BCM from the Rear Wiper Motor has not been received.
