Pinpoint Test A : One Or Both Low Beams Is Inoperative: Notes
WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1D00:11 | Left Low Beam: Circuit Short To Ground | A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the LH low beam output circuit. |
| B1D00:15 | Left Low Beam: Circuit Short To Battery Or Open | A continuous memory and on-demand DTC that sets when the BCM detects an open from the LH low beam output circuit. |
| B1D01:11 | Right Low Beam: Circuit Short To Ground | A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the RH low beam output circuit. |
| B1D01:15 | Right Low Beam: Circuit Short To Battery Or Open | A continuous memory and on-demand DTC that sets when the BCM detects an open from the RH low beam 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. 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 . |
