BCM DTC FAULT TRIGGER CONDITIONS

DTC	Description	Fault Trigger Conditions
B1315:11	Backlighting (Non Reflective Controls) Illumination Output: Circuit Short To Ground	This DTC sets in continuous memory and on-demand when the BCM detects an excessive current draw from the backlighting illumination output circuit.
B1315:15	Backlighting (Non Reflective Controls) Illumination Output: Circuit Short To Battery Or Open	This DTC sets in continuous memory and on-demand when the BCM detects a lower than expected current draw from the backlighting illumination output circuit.
U1000:00	Solid State Driver Protection Activated - Driver Disabled: No Sub Type Information	This DTC sets in continuous memory when the BCM has temporarily disabled an output driver because an excessive current draw exists (such as a short to ground). The BCM cannot enable the output until the cause of the excessive current draw is corrected, the BCM Diagnostic Trouble Codes (DTCs) have been cleared and a successful BCM self-test has been run.
U3000:49	Control Module: Internal Electronic Failure	Sets in continuous memory when the BCM has permanently disabled an output driver because an excessive current draw (such as a short to ground) has occurred more times than the BCM output driver can withstand. ADDRESS all other BCM Diagnostic Trouble Codes (DTCs). The cause of the excessive current draw must be corrected before a new BCM is installed.
