# Service bulletin SSM 52258

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: 10250522
- Published by NHTSA: 2024\-02\-23
- Manufacturer's number: SSM 52258
- Manufacturer's date: 2024\-02\-13
- NHTSA component: LATCHES/LOCKS/LINKAGES:DOORS:LOCK; ELECTRICAL SYSTEM

## NHTSA's summary

Some 2021\-2024 Bronco vehicles may exhibit a parasitic battery draw. This may be due to an interior door lock switch on the driver's and passenger's interior door panels. Prior to normal Workshop Manual \(WSM\) diagnostics, check both front door lock control switches for damage and/or proper operation. If a front door lock control switch does not operate as designed, repair as necessary. If no problems are found, continue with normal WSM diagnostics. For claiming, use causal part 14028 and applicable labor operations in Section 10 of the Service Labor Time Standards \(SLTS\) Manual. If the draw is still present, refer to WSM Section 414\-00 for normal diagnostics.

## 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.
- [TSB 26\-2380](/bulletins/11037537.md), 2026-09-29, Service bulletin: SUSPENSION; ELECTRICAL SYSTEM; STRUCTURE:BODY; UNKNOWN OR OTHER. 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.

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.
