Service bulletins for the 2026 Ram 1500

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.

To allow the sensor to update properly, drive the vehicle at highway speeds (above 20 MPH) for several miles (15 minutes). This ensures sufficient airflow and temperature sampling for accurate readings. If the temperature still does not update, proceed with standard diagnostic procedures.
9100463REV12025-12-17. Service bulletin. ELECTRICAL SYSTEM. 2024-2025 DT with DTC P0070 OR P0073 If Mirror Ambient Temperature Sensor (AATS) isnot reading temp correctly or setting DTC P0073, P0070 - allow the sensor to updateproperly by driving the vehicle at highway speeds (above 20 MPH) for several miles (15minutes). This ensures sufficient airflow and temperature sampling for accurate readings. If the temperature still does not update, proceed with standard diagnostic procedures. 2025-2026 DT with DTC P0071 AND P0073 (vehicles built on or between 07/01/2025 -07/29/2025 - If BOTH DTCs are present, before replacing the sensor, refer to the latest TSBin Service Library for additional repair procedure(s). - If NO DTC is present, but temperatureshown in the cluster/radio is higher than expected, allow the sensor to update properly bydriving the vehicle at highway speeds (above 20 MPH) for several miles (15 minutes). Thisensures sufficient airflow and temperature sampling for accurate readings. If thetemperature still does not update, proceed with standard diagnostic procedures.
