DTC U0423-68: Error Signal Received From Instrument Cluster [Adaptive Front Lighting System (AFS) Control Module]: Notes

DTC U0423:68 (ADAPTIVE FRONT LIGHTING SYSTEM CONTROL MODULE) DETECTION CONDITION AND POSSIBLE CAUSE

Description	Error signal received from instrument cluster Ignition switch error signal Selector lever position (R position) (AT)/reverse (MT) signal error Selector lever position (R position) (AT)/reverse (MT) signal not determined
DETECTION CONDITION	Ignition switch error signal The adaptive front lighting system (AFS) control module received ignition switch error signal for 5 s or more with the ignition switched ON (engine off or on). Selector lever position (R position) (AT)/reverse (MT) signal error The adaptive front lighting system (AFS) control module received selector lever position (R position) (AT)/reverse (MT) signal error for 5 s or more with the ignition switched ON (engine off or on). Selector lever position (R position) (AT)/reverse (MT) signal not determined The adaptive front lighting system (AFS) control module detected undetermined selector lever position (R position) (AT)/reverse (MT) signal.
Fail-safe	Ignition switch error signal Control of the adaptive front lighting system (AFS) is continued with the ignition switched ON (engine on). Control of the headlight auto leveling system is continued. Selector lever position (R position) (AT)/reverse (MT) signal error The swivel actuator is moved to the center. Control of the headlight auto leveling system is continued. Selector lever position (R position) (AT)/reverse (MT) signal not determined Control of the swivel actuator is continued with the transmission range switch (AT)/back-up light switch (MT) fixed in the condition when the malfunction is determined. Control of the headlight auto leveling system is continued.
Possible cause	DTCs are stored in the instrument cluster. Instrument cluster malfunction Adaptive front lighting system (AFS) control module malfunction
