DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
B1D06:09	Left Turn Indicator: Component Failure	A continuous memory and on-demand DTC that sets when the BCM detects a fault from the left turn lamp voltage supply circuit.
B1D06:11	Left Turn Indicator: Circuit Short to Ground	A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the left turn lamp voltage supply circuit.
B1D06:15	Left Turn Indicator: Circuit Short to Battery or Open	A continuous memory and on-demand DTC that sets when the BCM detects an open or short to voltage from the left turn lamp voltage supply circuit.
B1D07:09	Right Turn Indicator: Component Failure	A continuous memory and on-demand DTC that sets when the BCM detects a fault from the right turn lamp voltage supply circuit.
B1D07:11	Right Turn Indicator: Circuit Short to Ground	A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the right turn lamp voltage supply circuit.
B1D07:15	Right Turn Indicator: Circuit Short to Battery or Open	A continuous memory and on-demand DTC that sets when the BCM detects an open or short to voltage from the right turn lamp voltage supply circuit.
B12C4:11	Mirror Turn Indicator: Circuit Short To Ground	A continuous memory and on-demand DTC that sets when the DDM or PDM detects an open or short to voltage from the exterior mirror turn lamp voltage supply circuit.
B12C4:15	Mirror Turn Indicator: Circuit Short To Battery Or Open	A continuous memory and on-demand DTC that sets when the DDM or PDM detects an open or short to voltage from the exterior mirror turn lamp voltage supply circuit.
B1C98:11	Left Hand Corner Lamp Circuit: Circuit Short To Ground	A continuous memory and on-demand DTC that sets when the HCM detects a short to ground from the left front cornering lamp voltage supply circuit.
B1C98:13	Left Hand Corner Lamp Circuit: Circuit Open	A continuous memory and on-demand DTC that sets when the HCM detects an open from the left front cornering lamp voltage supply circuit.
B1C99:11	Right Hand Corner Lamp Circuit: Circuit Short To Ground	A continuous memory and on-demand DTC that sets when the HCM detects a short to ground from the right front cornering lamp voltage supply circuit.
B1C99:13	Right Hand Corner Lamp Circuit: Circuit Open	A continuous memory and on-demand DTC that sets when the HCM detects an open from the right front cornering lamp voltage supply circuit.
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 .
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 .
