# Service bulletin SSM 54522

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 11028166
- Published by NHTSA: 2026\-02\-04
- Manufacturer's number: SSM 54522
- Manufacturer's date: 2026\-01\-28
- NHTSA component: ELECTRICAL SYSTEM

## NHTSA's summary

Some 2025\-2026 Escape vehicles may exhibit an illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble code \(DTC\) P0073 stored in the powertrain control module \(PCM\) and/or B1B38 stored in the body control module \(BCM\). The vehicle may also exhibit no ambient air temperature reading shown in the instrument panel cluster \(IPC\) and/or center display screen. This may be due to a pinched, chafed, or severed wiring harness 15K867. To inspect the suspect area of the harness for damage, turn the steering wheel to the left and remove the four lower push pins from the front passenger side fender liner. Gently fold the liner inward and visually inspect the visible portion of harness 15K867 below the passenger side headlamp and follow the harness down behind the visible parts behind the front parking aid sensors.

- [SSM 55221](/bulletins/11038438.md), 2026-10-12, Service bulletin: UNKNOWN OR OTHER; POWER TRAIN; ELECTRICAL SYSTEM. For 20222026 vehicles equipped with a 8F35 transmission, a revision to the Road Testing Vehicle procedure has been made in the WSM, Section 307\-01 \> Diagnosis and Testing. This updated procedure improves the diagnosis of customer reported transmission concerns and aids in locating the proper root cause. During diagnosis and testing, details regarding whether the condition is more prevalent when the vehicle is hot or cold, throttle percentage at the time of occurrence, vehicle speed, the specific shift involved, and whether the issue occurs during transmission engagements \(N\>R, N\>D, R\>D, and/or D\>R\) should be noted in the warranty claim. Engineering requests including these detailed operating conditions that will significantly assist with root cause analysis. Diagnosis, testing, and repair should use established labor times outside this article.
- [TSB 26\-2428](/bulletins/11037776.md), 2026-10-02, Service bulletin: ELECTRICAL SYSTEM; FUEL/PROPULSION SYSTEM; UNKNOWN OR OTHER; POWER TRAIN. This bulletin supersedes 25\-2326. Reason for update: update the service procedure to include the fuel tank isolation valve replacement, update the causal part number, and increase the labor time allowance to include the fuel tank isolation valve replacement. Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble code \(DTC\) P2450 stored in the powertrain control module \(PCM\). This may be due to the software in the PCM and/or the fuel tank isolation valve.

- [SSM 55142](/bulletins/11037059.md), 2026-09-04, Service bulletin: POWER TRAIN; ENGINE; ELECTRICAL SYSTEM. Some 2023\-2025 Escape vehicles built on or before 16\-Sep\-2024 equipped with 1.5L EcoBoost engine may exhibit an "Engine Coolant Over\-Temperature" warning message displayed in the IPC and an illuminated MIL with DTCs P1285 and/or P1299 stored in the powertrain control module \(PCM\) during hard acceleration or under high load conditions. This may be due to machining chips trapped in the cylinder head causing a potential blockage in the coolant passage near the cylinder head temperature 2 \(CHT2\) port. To diagnose this condition, start the vehicle and idle for 15 minutes. Perform a road test at a temperature above \-20°C \(\-4°F\) and apply wide\-open throttle \(WOT\) hard accelerations in rapid succession. If the concern cannot be replicated, drain and refill the coolant system. If the concern can be replicated, drain the coolant system. Perform the Engine Cooling System Flushing procedure in Workshop Manual \(WSM\) \> 303\-03A Engine Cooling \- 1.5L EcoBoost \> General Procedures. Do not use the VC1 flush additive. Reassemble the engine. Fill and bleed the coolant system and re\-evaluate the concern. If the concern pers

- [SSM 55031](/bulletins/11035269.md), 2026-07-28, Service bulletin: UNKNOWN OR OTHER; FUEL/PROPULSION SYSTEM; ELECTRICAL SYSTEM. Some 2021\-2026 Ford/Lincoln vehicles may exhibit various symptoms including but not limited to the auto start/stop 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
