Code B172E 2014 Chevrolet Silverado Description

The safety alert seat provides a vibration in the driver’s seat bottom cushion to alert the driver of a number of concerns. Two seat haptic movement motors are utilized to create the vibration and are located on the left and right sides of the seat cushion. Utilizing two motors allows the vibration to be localized to the left or right side of the seat, depending on the side of the vehicle generating the alert, or to vibrate both simultaneously.

The Seat Memory Control Module receives serial data messages from other modules and provides voltage to control the seat haptic movement motors. The Seat Memory Control Module will pulse the left, right, or both motors with the number of pulses requested over serial data. The Seat Memory Control Module monitors the control circuits for open, short to ground, and short to voltage conditions and will set Diagnostic Trouble Code (DTC) if a circuit fault is detected.

The seat haptic movement motor is DC motor located in the driver’s seat bottom cushion. Two seat haptic movement motors are used in the seat bottom cushion, positioned on the left and right side. An offset weight is attached to the motor. When activated, the spinning offset weight creates a vibration felt by the driver through the seat cushion.

Each seat haptic movement motor receives a constant chassis ground. The motor is controlled by the Seat Memory Control Module providing voltage through a dedicated control circuit. When an alert is required, the Seat Memory Control Module will apply voltage, activating the seat haptic movement motor.
