Code U1716 Chevrolet 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 obstacles, has become trapped in it.
The power window low-speed serial data circuit is a unique two-way serial data communications link between the door module and the sensor.
State-of-health messages, the position of the window glass in relation to the distance traveled by the window, and the direction in which the window is moving are communicated via this circuit.
The Diagnostic Trouble Code (DTC) will be set by the driver door module (DDM), or by the passenger front door module (PFDM) when the DDM or the PFDM has detected any of the following conditions:
- The door module cannot communicate with the sensor over the power window low-speed serial data line.
- The power window low-speed serial data line is open.
- The power window low-speed serial data line is shorted to ground.
- The power window low-speed serial data line is shorted to battery.
- The window sensor battery voltage circuit has failed.
- The window sensor low reference circuit has failed.
