B2197 BUICK Description

The seat adjuster switch signal circuits are supplied 12 volts through resistors within the Memory Seat Module. When a seat adjuster switch is pressed the signal circuit is grounded.

The OBDII code is set when a seat adjuster switch input to the Memory Seat Module is active for more than 20 seconds.
