Convenience Opening/Closing

The GM and front door switch block modules provide the convenience open/close feature providing control of the power windows (and sunroof) from outside the vehicle with the key in the driver's door lock. The FZV (central lock receiver) provides the same function for opening only. The anti-trap feature is active during convenience closing from the driver's door lock. The convenience open feature provides outside activation of the windows and sunroof in the same manner. If the GM receives a request to operate convenience close or open for more than 110 seconds, the function is deactivated and a fault code is stored. The car memory feature can activate and deactivate the convenience open feature from the central locking control.
