Pinpoint Test A : One Or More Parking, Rear, Or License Plate Lamps Are Inoperative: Notes

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

Refer to Parking, Rear and License Lamps for schematic and connector information.

DTC Fault Trigger Conditions 

DTC Description Fault Trigger Conditions
B1098:11 Left Position Light: Circuit Short To Ground A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the LH front or rear parking lamps output circuit.
B1098:15 Left Position Light: Circuit Short To Battery Or Open A continuous memory and on-demand DTC that sets when the BCM detects an open from the LH front or rear parking lamps output circuit.
B1099:11 Right Position Light: Circuit Short To Ground A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the RH front or rear parking lamps output circuit.
B1099:15 Right Position Light: Circuit Short To Battery Or Open A continuous memory and on-demand DTC that sets when the BCM detects an open from the RH front or rear parking lamps output circuit.
B109B:11 License Plate Light: Circuit Short To Ground A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the license plate lamps output circuit.
B109B:15 License Plate Light: Circuit Short To Battery Or Open A continuous memory and on-demand DTC that sets when the BCM detects an open from the license plate lamps 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 .
