Headlamps — 2016 workshop reference 5625

DTC Description Fault Trigger Conditions B1D00:15 Left Low Beam: Circuit A continuous memory and on-demand DTC that sets when the BCM Short To Battery Or detects an open from the LH low beam output circuit. Open B1D01:11 Right Low Beam: Circuit A continuous memory and on-demand DTC that sets when the BCM Short To Ground detects a short to ground from the RH low beam output circuit. B1D01:15 Right Low Beam: Circuit A continuous memory and on-demand DTC that sets when the BCM Short To Battery Or detects an open from the RH low beam output circuit. Open U1000:00 Solid State Driver This DTC sets when the BCM has temporarily shut down the output driver. Protection Active -Driver The module has temporarily disabled an output because an excessive Disabled: No Sub Type current draw exists (such as a short to ground). The BCM cannot enable Information 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 This DTC sets when the BCM has permanently shut down the output driver. 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. CORRECT the cause of the excessive current draw before installing a new BCM.

Visual Inspection and Diagnostic Pre-checks

Inspect the headlamp assembly for damage. Verify BJB fuses 33 (20A) and 35 (20A) are OK

PINPOINT TEST A : ONE OR BOTH LOW BEAMS IS INOPERATIVE - EXCEPT CHINA

A1 DETERMINE IF ONE OR BOTH LOW BEAMS ARE INOPERATIVE

Ignition ON. Place the headlamp switch in the HEADLAMPS ON position.

Are both low beams inoperative?

Yes	GO to A9
No	VERIFY the BJB fuse 33 (20A) ( LH headlamp) or 35 (20A) ( RH headlamp) is OK. If OK, GO to A2 If not OK, REFER to the Wiring Diagrams manual to identify the possible causes of the circuit short. After the repair: If no Diagnostic Trouble Codes (DTCs) are present, TEST the system for normal operation. If DTC U1000:00 is present, CLEAR the Diagnostic Trouble Codes (DTCs) and REPEAT the self-test (required to enable the lamp output driver if DTC U1000:00 is present). If DTC U3000:49 is present, Click here to access Guided Routine (BCM).
