HEADUP DISPLAY SYSTEM, Diagnostic DTC:U0100, U0142, U0163, U023A, U1104

DTC Code	DTC Name
U0100	Lost Communication with ECM
U0142	Lost Communication with Main Body ECU
U0163	Lost Communication with Navigation Control Module
U023A	Lost Communication with Front Camera Module
U1104	Lost Communication with Driving Support ECU

DESCRIPTION

U0100: The meter mirror sub-assembly receives signals from the ECM via CAN communication.
U0142: The meter mirror sub-assembly receives signals from the main body ECU (multiplex network body ECU) via CAN communication.
U0163: The meter mirror sub-assembly receives signals from the multi-media module receiver assembly via CAN communication.
U023A: The meter mirror sub-assembly receives signals from the forward recognition camera via CAN communication.
U1104: The meter mirror sub-assembly receives signals from the driving support ECU via CAN communication.
