EDITOR’S NOTE: This article revises the previous version posted in January 2022.
There are several possible causes for the SRS DTC U3000-49 (Internal Failure of the SRS Unit) to be stored. If you can
duplicate the DTC, the troubleshooting will take you through the step-by-step process in isolating the faulty component.
In most situations, the SRS Unit should be last on the list of components to replace. Here is a quick tip for troubleshooting
a faulty seat weight sensor.
Disconnect all of the seat weight sensors and clear the DTCs. If DTC U3000-49 (Internal Failure of the SRS Unit) does not
reappear then replace the seat frame/rail.
NOTE: If you are using a seat frame from a known good vehicle, always find a vehicle with the same trim level. Swapping
seat frames with different trim levels may result in the same DTC condition and cause confusion.
