Driver Seat Module (DSM)

The DSM is on the universal asynchronous receiver-transmitter (UART)-based protocol (UBP) communication network. The DSM controls the positioning and programming of the driver seat and memory exterior rear view mirrors. Check the UBP network circuit between the DSM C341c and the DLC C251. The total resistance value must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the UBP network, damage to the DLC C251, damage to the DSM C341c, or a problem in the in-line connector. The DSM is located under the driver seat. For removal information, refer to MULTIFUNCTION ELECTRONIC MODULES . For additional driver seat information, refer to SEATING .
