Component Description: Notes

When the driver needs to change gear position the driver selects PRND or S by pressing a GSM button. The GSM reads the switch inputs 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 will act 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 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.
