2024-2026 Jeep/Dodge Radio Media Port DTC B15A1-00

Owners of certain 2024-2026 Jeep and Dodge vehicles may encounter a diagnostic trouble code (DTC) B15A1-00 related to the media port connection in the Radio (ETM) module. This issue is detailed in Manufacturer Communication S2508000091, released in October 2025 by Stellantis, which covers various Jeep and Dodge models.

The communication clarifies that this DTC B15A1-00 often appears without any noticeable problems for the driver or passengers. Engineering is actively investigating a software update to prevent this code from setting incorrectly in the future.

Symptoms

The primary symptom of this issue is the presence of DTC B15A1-00, specifically "Media Port 1 Connection," when a vehicle scan report is performed. It's important to note that this code frequently sets without any accompanying customer concerns, warning lights on the dashboard, or error messages displayed on the infotainment system. For example, owners might not experience issues with USB device connectivity, audio playback from connected devices, or charging functions through the media port. Therefore, the presence of the Jeep Radio DTC B15A1-00 alone does not necessarily indicate a functional problem.

Fault Codes / DTCs

The specific diagnostic trouble code addressed by this manufacturer communication is:

This DTC B15A1-00 is described as being stored in the Radio (ETM) module.

Diagnosis and Trigger Conditions

According to Manufacturer Communication S2508000091, the presence of DTC B15A1-00 in the Radio (ETM) module should be evaluated based on accompanying symptoms. If there are no customer concerns, no warning lights illuminated on the instrument cluster, and no error messages displayed, this DTC can generally be ignored. This indicates that the code is likely setting erroneously without an actual fault.

However, if a customer concern is directly associated with the media port's functionality (e.g., devices not connecting, charging issues, or audio problems), or if the DTC B15A1-00 is reported as "Active" during a diagnostic scan, then further investigation is warranted. In such cases, technicians should follow the standard DTC diagnostics procedures to identify the root cause of the problem.

Important Warnings for Owners

Owners should be aware of specific guidance provided in this communication:

• Do not replace components unnecessarily: If diagnostic procedures are followed and no actual issues are identified, the manufacturer explicitly states, "do not replace any components." This is crucial to prevent unnecessary repairs and costs.
• No automatic warranty repairs: The document notes, "This document does not authorize warranty repairs." This means that simply having the stored DTC B15A1-00 without an active symptom or confirmed fault may not qualify for a warranty repair.
• Software update pending: Engineering is actively investigating a software update to prevent this Jeep Radio DTC B15A1-00 from setting erroneously in the future. Owners should monitor for future announcements regarding such an update.

Owner Action

If you own a 2024-2026 Jeep or Dodge vehicle and a scan reveals a stored DTC B15A1-00 for the media port connection, first assess if you are experiencing any actual problems. If your media port functions normally, there are no warning lights, and no messages on your infotainment screen, then, as per Manufacturer Communication S2508000091, this code can likely be ignored.

If, however, you are experiencing issues such as your media port not working, devices not connecting, or if you see an active warning related to the media port, you should schedule an appointment with your authorized dealer for diagnosis. Be sure to describe the specific symptoms you are experiencing. It's important to remember that if diagnostics confirm no actual fault, component replacement is not recommended.
