B10A6:92	Main Light Switch: Performance or Incorrect Operation	GO to Pinpoint Test C
B1D00:11	Left Low Beam: Circuit Short to Ground	GO to Pinpoint Test A
B1D00:15	Left Low Beam: Circuit Short to Battery or Open	If the low beam is inoperative, GO to Pinpoint Test A If the low beam is always on, GO to Pinpoint Test C
B1D01:11	Right Low Beam: Circuit Short to Ground	GO to Pinpoint Test A
B1D01:15	Right Low Beam: Circuit Short to Battery or Open	If the low beam is inoperative, GO to Pinpoint Test A If the low beam is always on, GO to Pinpoint Test C
U3000:49	Control Module: Internal Electronic Failure	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. The cause of the excessive current draw MUST be corrected before a new BCM is installed. ADDRESS all other Diagnostic Trouble Codes (DTCs) first. After the cause of the concern is corrected, INSTALL a new BCM. Refer to: Body Control Module (BCM) .
