Component Description: Notes

WARNING: This page is about a different variant/trim than selected.

When the driver needs to change gear position the driver selects PRND or L by rotating a GSM dial. The GSM senses the dial position and sends a request over the High Speed Controller Area Network 2 (HS2-CAN) through the GWM over the High Speed Controller Area Network 1 (HS1-CAN) to the PCM. The PCM receives the input from the GSM, combines in vehicle conditions to determine commanded transmission range then sends a command to the TRCM through a GWM over the High Speed Controller Area Network 2 (HS2-CAN). The TRCM acts on the command from the PCM by moving the transmission to the commanded position via a selector lever shift cable. The PCM reads the transmission range sensor (TRS) and confirms the correct position has been achieved. The PCM then sends a message to the GSM and the IPC to display the current transmission range.
