Circuit System Description
WARNING: This page is about a different variant/trim than selected.
The K9 Body Control Module provides a signal circuit to the S3 Transmission Manual Shift Switch. The ground circuit for the S2 Transmission Manual switch is connected to chassis ground. The K9 Body Control Module monitors the voltage on the signal circuit to the S2 Transmission Manual Shift Switch. The voltage drop across the S2 Transmission Manual Shift Switch changes when the plus (+) or minus (-) button is pressed. The K9 Body Control Module communicates the shift request to the K71 Transmission Control Module via serial data.
