Unlocking The Mystery Of U1531 Fault Code
The U1531 fault code is related to the Local Interconnect Network (LIN) Bus in automobiles.
LIN Bus is a single wire transmission system with a speed of 10.417 Kbits.
The LIN circuit is used to transmit serial data between the master control module and other LIN devices in a subsystem. If the serial data communication is lost between any of the LIN devices, the master control module will set a no communication code against the non-communicating LIN device. The U1531 code is set when the Headlamp Control ModuleHeadlamp Leveling Control Module loses communication with the Left Headlamp Assembly on the LIN Bus.
