DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
B1445:11	Rear Park Lamps Output: Circuit Short to Ground	A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the rear parking lamp output circuit.
B1445:15	Rear Park Lamps Output: Circuit Short to Battery or Open	A continuous memory and on-demand DTC that sets when the BCM detects an open from the rear parking lamp output 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.
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.
