Pinpoint Test B : An Individual Front Fog Lamp Is Inoperative: Notes
WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Fog Lamps for schematic and connector information.

DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1147:11 | Left Front Fog Lamps: Circuit Short To Ground | A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the LH fog lamp output circuit. |
| B1147:15 | Left Front Fog Lamps: Circuit Short To Battery or Open | A continuous memory and on-demand DTC that sets when the BCM detects an open from the LH fog lamp output circuit. |
| B1148:11 | Right Front Fog Lamps: Circuit Short To Ground | A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the RH fog lamp output circuit. |
| B1148:15 | Right Front Fog Lamps: Circuit Short To Battery or Open | A continuous memory and on-demand DTC that sets when the BCM detects an open from the RH fog 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. For additional information on BCM Field Effect Transistor (FET) protection, REFER to: Body Control Module (BCM) - 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: Body Control Module (BCM) - System Operation and Component Description . |
Possible Sources
- Bulb
- Wiring, terminals or connectors
- BCM
Visual Inspection and Diagnostic Pre-checks
- Verify the BJB fuse 48 (50A) (LH fog lamp) or fuse 50 (50A) (RH fog lamp) is OK.
- Inspect the bulbs and make sure they are OK.
