DTC No.	Detection Item	DTC Detection Condition	Trouble Area	Note
U0182	Lost Communication with Lighting Control Module Front	No communication from the headlight leveling ECU assembly continues. (for Single Beam Headlight) No communication from the headlight light control ECU sub-assembly LH continues. (for Triple Beam Headlight)	Headlight leveling ECU assembly branch line or connector (for Single Beam Headlight) Power source circuit of headlight leveling ECU assembly (for Single Beam Headlight) Headlight leveling ECU assembly ground circuit (for Single Beam Headlight) Headlight leveling ECU assembly (for Single Beam Headlight) Headlight light control ECU sub-assembly LH branch line or connector (for Triple Beam Headlight) Power source circuit of headlight light control ECU sub-assembly LH (for Triple Beam Headlight) Headlight light control ECU sub-assembly LH ground circuit (for Triple Beam Headlight) Headlight light control ECU sub-assembly LH (for Triple Beam Headlight)	HINT: The network gateway ECU stores DTCs when it detects a communication stop or network communication error for ECUs connected to sub bus 2. (for Single Beam Headlight) The main body ECU (multiplex network body ECU) stores DTCs when it detects a communication stop or network communication error for ECUs connected to sub bus 1.
