Code U1715 GMC Description

Express Up operation of the front door power windows is monitored and controlled by the front door modules and the window sensors. Each front door window motor has a window sensor mounted to it. The Driver Door Module (DDM) and the Passenger Front Door Module (PFDM) each supply battery voltage and ground to power their respective window sensors. The door modules and sensors communicate with each other via a power window high-speed serial data circuit, and a power window low-speed serial data circuit.
The window sensor detects differences in the window motors electrical pulses to determine if there is an obstruction to the travel of the window glass. The door modules use the information generated by the sensors to disable the Express-Up movement of a window or reverse the direction of travel, in the event that a passenger, or other obstacle, has become trapped in it.
The power window high-speed serial data circuit is a unique one-way communications link between the sensor and the door module. The sensor uses a voltage signal, and also a 1kHz signal, to transmit information, via this circuit, from the sensor to the door module.
The Diagnostic Trouble Code (DTC) will be set by the Driver Door Module (DDM) or the Passenger Front Door Module (PFDM) when the DDM or PFDM detects either of the following conditions: The power window high-speed serial data circuit voltage is a constant low for 112 milliseconds while the window is not moving or the power window high-speed serial data circuit 1 kHz signal is active for a period of 112 milliseconds while the window is not moving.
