DRLs Dim To Park Intensity After Turn Signal Lamp Is Cancelled
Model:
Ford Built on or before 01-Nov-2022
2021-2023 Bronco Sport
Issue: Some 2021-2023 Bronco Sport vehicles built on or before 01-Nov-2022 equipped with light emitting diode
(LED) control module (A2C7636130500 printed onto the module label) may exhibit a condition where the daytime
running lamps (DRLs) stay on for up to 10 minutes after the vehicle is turned off and/or daytime running lamps
momentarily dim to park intensity when the turn signal lamp is cancelled before returning to full DRL intensity. This
may be due to the software in the LED control module. To correct this condition, follow the Service Procedure to
replace both LED control modules and update the configuration of the body contro! module (BCM).
Action: Follow the Service Procedure to correct the condition on vehicles that meet all the following criteria:
* 2021-2023 Bronco Sport
+ Built on or before 01-Nov-2022
+ Equipped with LED control module (A2C7636130500)
+ At least one of the following conditions:
- Daytime running lamps stay on for up to 10 minutes after the vehicle is turned off
- Daytime running lamps momentarily dim to park intensity when the turn signal lamp is cancelled
before returning to full DRL intensity.

Condition Code:
Service Procedure
A WARNING: For the vehicle safety systems to operate as intended, a configuration update will need to
be performed when LED control modules have been changed. Failure to do so may increase the risk of a
flickering condition in the headlamps. Carefully read this bulletin and the instructions given in Ford
Diagnosis and Repair System (FDRS).
NOTE: For 2022 Bronco Sport vehicles, make sure that the following procedure is performed only if the
vehicle identification number (VIN) is not listed in the Field Service Action (FSA) 22C22. The new LED control
modules contain the software fix for this concern.
1. Using the latest version of the FDRS scan tool, check for diagnostic trouble codes (DTCs) stored in the body
control module. Does the vehicle exhibit a DTC B1533 or do the DRLs stay on for more than 10 minutes?
(1). Yes - this article does not apply, perform normal diagnostics outside of this article. Refer to the Workshop
Manual (WSM), Section 417-01 Exterior Lighting > Diagnosis and Testing > Pinpoint test A.
(2). No - proceed to Step 2.
2. Inspect both LED control module part numbers using a mirror. The part number is in the lower section of the LED
control module. (Figure 1)

3. Determine if the vehicle has an LED control module part number indicated in the image. (Figure 2, Callout 1) Does
the vehicle have the LED control module part number A2C7636130500 as indicated in the image?

(1). Yes - replace both LED control modules. Refer to the WSM, Section 417-01 Exterior Lighting > Removal and
Installation. Proceed to Step 4.
NOTE: It is not necessary to perform the BCM-Local Interconnect Network (LIN) New Module Initialization
app after the installation of the new LED control modules. The Initialization routine is included in the BCM-
Light Emitting Diode (LED) Control Module Configuration app and will be performed automatically.
(2). No - this article does not apply.
4. Using FDRS scan tool, check the BCM for software updates.
(1). Download and run the BCM-Body Control Module (BCM) Software Update.
5. Run the BCM-Light Emitting Diode (LED) Control Module Configuration app. Follow the on-screen instructions to
update the BCM configuration.
(1). A password will be required to run the BCM-Light Emitting Diode (LED) Control Module Configuration app.
Use the password 05660159.
6. Perform the following headlamp validation tests with the key ignition on and confirm for proper operation.
(1). Position the left steering column multifunction switch in the high beam position and confirm the correct
operation of the headlamps.
(2). Position the left steering column multifunction switch in the low beam position and confirm the correct
operation of the headlamps.
(3). Position the headlamp switch to parking lamps position and confirm the correct operation of the parking
lamps.
(4). Apply the brake pedal and confirm with the help of another technician that the rear lamps and high mounted
stop lamps remain lit during turn signal activation in night mode
(5). Push the left steering column multifunction switch up and down to activate the direction indicators. Confirm
that the front and rear turn lamps are flashing.
(3)
7. For North America market vehicles except Canada, validate the DRL functionality and perform the following tests.
An assistant may be needed outside of the vehicle.
NOTE: For the next steps, it is important to park the vehicle in a well-lit area.
NOTE: DRL and Park function use the same lit elements within the lamp. The park function use a lower
intensity output intended to be seen at night without blinding or distracting other drivers. The DRL function
use a much higher intensity output in order to be seen during the day. During the validation tests below, DRL

refers to the higher intensity output and Park intensity refers to the lower intensity output intended for
nighttime use.
(1). Make sure to enable the DRLs in the center display screen. To enable DRLs, turn the ignition on. Press the
vehicle settings button. Select lighting in the menu. Swipe to the right to enable the daytime running lights.
(2). Turn the ignition on, position the headlamp switch in the off position, apply the parking brake, position the
gearshift module in drive (D). Confirm that the DRL remains off.
(3). Turn the ignition on, position the headlamp switch in the off position, apply the parking brake, position the
gearshift module in drive (D) and activate the turn signal lamp. Confirm that the DRL remains off and the turn
signal activated remains flashing.
(4). Turn the ignition on, position the headlamp switch in the parking lamps position, apply the parking brake and
position the gearshift module in drive (D). Confirm that the parking lamps turn on.
(5). Turn the ignition on, position the headlamp switch in the parking lamps position, apply the parking brake,
position the gearshift module in drive (D) and activate the turn signal lamp. Confirm that the parking lamps turn on
and the turn signal activated remains flashing.

the gearshift module in drive (D), activate or deactivate the fog lamps and activate the turn signal lamp. Confirm
that the DRL turns off on the side of the turn signal activated and then turns back on after the turn signal is
cancelled.
(9). Turn the ignition on, position the headlamp switch in the low beam position, apply the parking brake, position
the gearshift module in drive (D). Confirm that the low beams turn on and position intensity.
