ELECTRICAL 164 OPERATION: Controller allows windows to move when the following inputs are present.  Ignition is ON or  Simulated Ignition from BCM is high If any of the input is present, then window winding controller will operate the motor as per window winding Switch request. The BCM Accessory Relay output is connected to the Window winding controller and the mirror fold relay. Whenever the vehicle power state is IGNITION or RUN the BCM accessory relay output should be high. When the vehicle engine is stopped by the user, the accessories should remain powered for 3 Min. to allow powered functions to be performed without turning the key to the ignition position again. ( E.g. close electric windows and fold ORVM ). When the vehicle power state changes from IGNITION to OFF or KEY IN SENSOR, the BCM Accessory Relay output will remain high for 3 minutes. NOTE: If driver door is opened, then Acc delay get immediately cancelled. There is an individual switch at each window and a set of switches in the driver's door, so the driver can operate all the windows. Switches are used only to provide a mode signal to controller for further operation. Motor current does not pass through the Switches. Each switch has four positions,  OFF  Manual Up ( MU )  Manual Down ( MD )  Auto Down ( AD) When a particular mode is operated, ground signal appears on particular terminal MU, MD or AD. In case of Auto down ground signal appears on both MD and AD terminals. Child Lock Functionality In switch circuit driver has an option to disable the passenger switches (only rear door LH/ RH) by locking the window lock switch ( Inside the driver door window winding switch ). When parking is switched ON, LED on the window winding switches of driver as well as passenger switches will be ON. Lock/Unlock switch RED LED will be on when it is in child Lock (Inhibit) mode. Window winding controller functionality during cranking: During cranking the vehicle, the following are the window winding operations,  In Manual Up and Manual Down mode, the windows stop moving during cranking and only start moving after cranking if the user is still operating the switch.  If Auto Down is active and user cranked the vehicle, then window movement should stop until vehicle get cranked and after that auto down function get automatically activated without user intervention.
