module (RCM) when a diagnostic self-test is performed. If there are no observable vehicle symptoms, the DTC will clear using the "Self-Test" application in the Ford Diagnosis and Repair System (FDRS). Replacement and/or programming of the RCM is not needed to correct this condition. If there is an observable vehicle symptom and/or the DTC will not clear, follow normal Workshop Manual diagnostics.

message displayed on the instrument panel cluster (IPC).- Key fob does not work in the backup slot. - Remote keyless entry (RKE) (lock and unlock from the key fob) functionality will work to lock/unlock the vehicle. If the vehicle exhibits these symptoms, manually enter the vehicle identification number (VIN) into the VIN entry dialog in the Ford Diagnosis and Repair System (FDRS) and then start a session using the Vehicle Communication Module (VCM) II, VCM 3, Vehicle Communication and Measurement Module (VCMM) or later level device with a universal serial bus (USB) cable disconnected from the laptop. Download the "BCM - Body Control Module (BCM) Hardware Test" application from the Toolbox. Select "Run" and connect the VCM II, VCM 3, VCMM or later device USB cable to the laptop. Follow the instructions as directed by the "BCM - Body Control Module (BCM) Hardware Test" guided routine. For claiming, use causal part 15604 and labor operation

This may be due to the software in the audio control module (ACM). To determine if it is a software concern, disconnect the 12-volt battery cables for 10 minutes and reconnect. If the concern is still present, continue with normal diagnostics in Workshop Manual (WSM), Section 415-00 Information and Entertainment System > General Information > Diagnosis and Testing and repair as necessary outside of this article. If the no audio/sound concern is resolved, reprogram the ACM using the latest software level of the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 18806 and labor operations 12651D and 12651D4.

system not operating as intended with a "Check Charging System" message in the instrument panel cluster (IPC) while the charging system is operating properly with no charging related diagnostic trouble codes (DTC) stored. This may be due to someone using an aftermarket programmer to change the body control module (BCM) configuration to disable the auto start/stop system or perform other unsupported programming modifications. To correct this condition on F-150 and Bronco vehicles, download and run the Ford Diagnosis and Repair System (FDRS) application titled "BCM-Charging System Configuration Correction". Running this application will determine if the BCM configuration was modified by the customer and if so, provide the option to return the configuration back to factory settings. For other vehicle models exhibiting concerns related to unsupported aftermarket BCM programming, submit a Technical Support Request (TSR) requesting support to revert the BCM configuration

a warning light to illuminate for one key cycle

The maximum number of keys that are allowed to be programmed is now 4. This is due to the architecture of the body control module (BCM) changing that now limits the number of keys programmed. Ford Diagnosis and Repair System (FDRS) has been updated to reflect that 4 keys are the maximum number of keys to be programmed. The Workshop Manual (WSM), Section 419-01B > Description and Operation has also been updated to reflect this update.

feature code HLLAM) may not be able to connect the harness to the vehicle after the upfit has been completed. This may be due to the harness being too short in length. To correct this condition, order a new BLIS kit harness using service part number RK3Z-15K868-A. <br /><br /> To confirm a vehicle is built with a certain minor feature code, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner in the Professional Technician System (PTS).

Reason for update: To update the production cutoff date for Transit vehicles. Some of the vehicles listed in the Model statement above may exhibit an illuminated MIL with DTC P2C90 stored in the powertrain control module (PCM). This may be due to the software in the PCM.

display may exhibit a condition where the fuel gauge displays up to the 8th mark below full fuel level when the fuel tank is full. This condition does not affect vehicle durability and no additional diagnosis or service is required at this time. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected by the end of Q3 2026. Replacement/reprogramming of the IPC will not resolve this condition. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available. If this condition is encountered, enter a vehicle identification number (VIN) and click the "Submit Global Concern Report (GCR)" link at the upper right of the PTS "Vehicle ID" screen. Fill out the GCR form, referencing this article number in the report. Do not use the "Report A Problem" link to submit a report for this condition.

The vehicle's rear belt monitor system will operate as designed once transport mode is exited and the vehicle enters normal mode after a key cycle. This condition does not affect vehicle durability, and no additional diagnosis or service is required for this fault message at this time.

defrost features after a remote start is performed through the Ford mobile application or with the key fob. Customers may also experience heated/cooled seats, heated steering wheel and/or front/rear defrost features turning on in unexpected conditions such as during warmer weather. These features will operate normally when commanded in the center display screen. This may be due to the customer not setting up their "Climate Settings" through the Ford mobile application. To correct this condition, inform the customer they should perform a remote start from the Ford mobile application and then adjust the "Climate Settings" in the Ford mobile application as desired. These settings only need to be set once and will persist through subsequent remote starts. Heated and cooled seats will be set to Level 2 when turned ON via "Climate Settings" in the Ford mobile application during a remote start event. This is normal operating characteristic. This condition does not affect vehicle durability and no a

Reason For Update: add 2026 model year vehicles, update LV fluid XT-10-QLVC and CXT-10-LV6 description to add "Transfer Case Fluid 4WD Only", and update Step 4 to inspect/replace 7H351 and 7B177 outside of this article. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: - No upshift past second gear - Unable to achieve third gear ratio - Illuminated MIL with DTCs P0757 and P2701 This may be due to a damaged one-way clutch (OWC).
