General Description

Power window main and assist switch node generate LIN data byte (signals) and transfer this data byte (containing several move commands, i.e. Manual or Auto Up/Down) to each safety power window ECU.
Some data bits are used for operation of power window motors.
These safety power window ECUs are also connected to local switches, therefore these switches can be used in case that LIN is out of order. On the contrary, in the rear door, the switch can control the motor directly.
*Signal priority
(1) Front door : LIN command has always priority to switch signal. Therefore, as long as LIN is not out of order, switch can't control motor in front door.
(2) Rear door : The priority can be ordered as bellow : the priority depends on not signal source but command. (Manual > Auto)






DTC Description

The power window main switch module sets DTC R/DRIVER SAFETY P/WDW LIN COMM. ERR if the switch module detects disconnection of the LIN communication circuit.
