    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    BCM B103C:01 Left Headlamp Control: General Electrical Failure A continuous memory and on-demand DTC that sets in the HCM if the adaptive front lighting module senses a LED outage or an adaptive front lighting module LED driver failure.
    BCM B103D:01 Right Headlamp Control: General Electrical Failure A continuous memory and on-demand DTC that sets in the HCM if the adaptive front lighting module senses a LED outage or an adaptive front lighting module LED driver failure.
    BCM B14E2:11 Exterior Lamps Power Supply "E": Circuit Short To Ground A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the LH high beam voltage supply circuit.
    BCM B14E2:15 Exterior Lamps Power Supply "E": Circuit Short To Battery Or Open A continuous memory and on-demand DTC that sets when the BCM detects an open from the LH high beam voltage supply circuit.
    BCM B14E3:11 Exterior Lamps Power Supply "F": Circuit Short To Ground A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the RH high beam voltage supply circuit.
    BCM B14E3:15 Exterior Lamps Power Supply "F": Circuit Short To Battery Or Open A continuous memory and on-demand DTC that sets when the BCM detects an open from the RH high beam voltage supply circuit.
    BCM B1D02:11 Left High Beam Circuit: Circuit Short To Ground A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the LH high beam output circuit.
    BCM B1D02:15 Left High Beam Circuit: Circuit Short To Battery Or Open A continuous memory and on-demand DTC that sets when the BCM detects an open from the LH high beam output circuit.
    BCM B1D03:11 Right High Beam Circuit: Circuit Short To Ground A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the RH high beam output circuit.
    BCM B1D03:15 Right High Beam Circuit: Circuit Short To Battery Or Open A continuous memory and on-demand DTC that sets when the BCM detects an open from the RH high beam output circuit.
    BCM U1000:00 Solid State Driver Protection Active -Driver Disabled: No Sub Type Information This DTC sets when the BCM has temporarily shut down the output driver. The module has temporarily disabled an output because an excessive current draw exists (such as a short to ground). The BCM cannot enable the output until the cause of the short is corrected, the Diagnostic Trouble Codes (DTCs) have been cleared and a successful self-test is run. For additional information on BCM Field Effect Transistor (FET) protection, REFER to: Module Controlled Functions - System Operation and Component Description .
    BCM U3000:49 Control Module: Internal Electronic Failure This DTC sets when the BCM has permanently shut down the output driver. The module has permanently disabled an output because an excessive current draw fault (such as a short to ground) has exceeded the limits that the BCM can withstand. CORRECT the cause of the excessive current draw before installing a new BCM. For additional information on BCM Field Effect Transistor (FET) protection, REFER to: Module Controlled Functions - System Operation and Component Description .
