Module Network Input Messages - PDM
| Broadcast Message | Originating Module | Message Purpose |
|---|---|---|
| Passenger mirror command | DDM | When the exterior mirror control switch requests movement of the RH exterior mirror, the DDM sends the request to the PDM to drive the RH exterior mirror motor in the desired direction. |

System Operation - Exterior, Power
The power mirrors allow the LH and RH exterior mirror glass to be positioned electronically. All functions of the power mirror feature are integrated into one switch module (integral to the LH front door window control switch). The LH or RH selection switch determines which exterior mirror glass is controlled.
When the exterior mirror directional pad switch is pressed left, right, up or down with the LH or RH exterior mirror selected, the movement request is sent to the DDM through a LIN circuit. If the LH mirror is selected, the DDM supplies voltage and ground to the appropriate LH exterior mirror motor. If the RH mirror is selected, the DDM sends the passenger mirror command message with the input from the exterior mirror control switch to the PDM. The PDM then supplies voltage and ground to the appropriate RH exterior mirror motor. The DDM and PDM controls the glass movements by reversing polarity of the voltage and ground circuits being supplied to each motor.
