U156D: The Low Fuel Pressure Warning You Can’t Ignore

The U156D code is related to the Local Interconnect Network (LIN) Bus. It occurs when the Chassis Control Module loses communication with the Transmission Shift Lever on the LIN Bus. This happens when the master control module detects a loss of serial data communication between any of the LIN devices on the LIN bus network.

The Diagnostic Trouble Code (DTC) is set when a supervised periodic message from the Transmission Shift Lever to the Chassis Control Module is not received.

FAQ
