# Service bulletin TSB 22\-2190

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: 10211911
- Published by NHTSA: 2022\-05\-16
- Manufacturer's number: TSB 22\-2190
- Manufacturer's date: 2022\-05\-13
- NHTSA component: ELECTRICAL SYSTEM; AIR BAGS:SRS MALFUNCTION WARNING LAMP/LIGHT

## NHTSA's summary

Some 2020\-2022 Explorer/Aviator and 2021\-2022 Bronco vehicles may exhibit an illuminated airbag warning indicator with diagnostic trouble code \(DTC\) B1404:13 and/or B1407:13. This may be due to contamination and relative movement in the connection between the wiring harness and the side airbag. To correct the condition, follow the Service Procedure to replace the affected connector with a service pigtail and the affected side airbag.

## 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\-2395](/bulletins/11036595.md), 2026-09-01, Service bulletin: POWER TRAIN; UNKNOWN OR OTHER; ELECTRICAL SYSTEM. This article supersedes 26\-2287. Reason for update: update the labor operation numbers to add MT to operations C, F, G, H, J, K, L and M, and correct the part number LIMZ\-4A015\-B to L1MZ\-4A015\-B. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: Harsh engagement Delayed engagement Harsh shift Delayed shift Illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble codes \(DTC\)s P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7 stored in the powertrain control module \(PCM\) or transmission control module \(TCM\). This may be due to axial movement of the CDF clutch cylinder sleeve causing hydraulic circuit leaks. NOTE: If internal transmission service is required to address a concern detected with the CDF clutch cylinder following this article, technicians should carefully inspect and replace other transmission components and flush transmission fluid cooler only as ne
- [SSM 55069](/bulletins/11036103.md), 2026-08-11, Service bulletin: VISIBILITY/WIPER; ELECTRICAL SYSTEM; STRUCTURE:BODY. Some 2020\-2025 Explorer vehicles equipped with a power roof opening panel may exhibit a sunshield with localized bunching or binding/inoperative. This may be due to a broken or missing sunshield fabric retainer/clip. A revised sunshield clip \(LJ6Z\-5452118\-B\) is now available to address this condition. It is not necessary to replace the entire sunshield assembly if the clip\(s\) are broken or missing. Refer to Workshop Manual \(WSM\), Section 501\-17 Roof Opening Panel \> General Procedures \> Inspection and Replacement of the Roof Opening Panel Shield Clip.
