U172A Fault Code: Understanding The Steering Angle Sensor Circuit!
The U172A fault code is related to the Local Interconnect Network (LIN) Bus.
It occurs when the Left High Beam Control Module loses communication with the Left Headlamp Horizontal Motor. This fault code is set when a supervised periodic message is not received by the Left High Beam Control Module.
The LIN Bus is a single wire with a transmission rate of 10.417 Kbits.
If serial data communication is lost between any of the LIN devices on the LIN bus network, the master control module will set a no communication code against the non-communicating LIN device.
