Code B2101 Buick Description

When the Power Seat Switches are pressed, the Memory Seat Module (MSM) receives an input from the switch. The MSM commands the driver seat to move in response to the switch input. If a seat switch continues to be active for 30 seconds after the motor controlled by that switch reaches the end of its travel, the switch will be considered shorted and the MSM will set the Diagnostic Trouble Code (DTC) or if a position sensor DTC is current and the associated switch is active for 30 continuous seconds, the switch will be considered shorted and the MSM will set the DTC.
