# Service bulletin TSB 26\-2380

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: 11037537
- Published by NHTSA: 2026\-09\-29
- Manufacturer's number: TSB 26\-2380

- NHTSA component: SUSPENSION; ELECTRICAL SYSTEM; STRUCTURE:BODY; UNKNOWN OR OTHER

## NHTSA's summary

This article supersedes TSB 25\-2575 to update the Parts list to add the applicable body wiring harnesses and underbody shield bolts. Some vehicles listed in the Model statement above may exhibit a "Sta\-bar Disconnect Service Required" message in the instrument panel cluster \(IPC\) with any of the following diagnostic trouble codes \(DTCs\) stored in the chassis control module \(CHCM\): C103A, C1A99, C1B03, C1B07, C1B14 and/or B1A67. This may be due to water intrusion in the stabilizer bar wiring harness connector.

## Other bulletins for the same vehicles and component

- [SSM 55240](/bulletins/11038445.md), 2026-10-13, Service bulletin: ELECTRICAL SYSTEM; UNKNOWN OR OTHER; SERVICE BRAKES. Some 2021\-2024 Bronco vehicles may exhibit an illuminated red brake warning indicator with diagnostic trouble code \(DTC\) C0049:01 stored in the anti\-lock brake system \(ABS\) module. This may be due to pin fitment at the brake fluid level sensor connector. To resolve this concern, replace the brake fluid reservoir and replace the brake fluid level sensor electrical connector C1052 with service pigtail wiring kit 3U2Z\-14S411\-BXAB. For claiming, use causal part 2L210 and labor operations 2140A and 2219D45WR.

- [SSM 55118](/bulletins/11036529.md), 2026-09-01, Service bulletin: ELECTRICAL SYSTEM; UNKNOWN OR OTHER; STRUCTURE:BODY. Some of the following vehicles: \* 2023\-2025 F\-Super Duty built on or before 02\-Feb\-2025 \* 2024\-2026 Ranger/Bronco/Mustang \* 2024\-2025 F\-150 built on or before 15\-Jul\-2025 \* 2024\-2025 Nautilus built on or before 16\-Feb\-2025 \* 2025 Explorer/Aviator built on or before 01\-Feb\-2025 may exhibit all of the following symptoms: \- "No Key Detected" 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, start the vehicle using both key fobs. If the no crank/no start condition with "No Key Detected" concern is present, reprogram both key fobs and retest. If the no crank/no start condition with "No Key Detected" is still present, replace the body control module \(BCM\). Refer to Workshop Manual \(WSM\), Section 419\-10. For claiming, use causal part 15604 and labor operation MT55118SSM up to 1.8 hours.
- [SSM 55079](/bulletins/11036285.md), 2026-08-20, Service bulletin: ELECTRICAL SYSTEM; UNKNOWN OR OTHER. Some 2025\-2026 Bronco vehicles equipped with a 7 speaker audio system \(minor feature code IDBAL\) may exhibit diagnostic trouble codes \(DTC\) B128A:01, B128A:11, B128A:12, B128A:13, B1288:11, B1288:12 and/or B1238:17 stored in the audio front control module \(ACM\) with no customer facing symptoms related to those DTCs. Clear the DTCs and if the DTCs return with no customer facing symptoms, this condition may be due to the ACM software. Replacement of the ACM and/or speakers will not resolve this condition. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected in Q4 2026. Continue to monitor Professional Technician System \(PTS\) for additional information and schedule service appointments for customers once the repair becomes available. If a vehicle exhibits this condition, enter the 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.
