Test D4-D5:
Normal Operation
The FEM receives power (hot at all times) from the rear battery junction box (BJB) through circuit 30-AJ80 (RD/OG). With the key in ON, the REM provides power to the driver window control switch through circuit 7-AJ7 (YE/RD) and to the passenger window control switch through circuit 7-AJ18 (YE/VT). The FEM provides power to the driver window motor while the rear electronic module (REM) provides power to the passenger window motor. The FEM senses the driver window position using sensors in the window motor and the REM senses the passenger window position using sensors in the window motor. The delayed accessory feature will turn off power to the windows (from the FEM and REM) whenever the key is turned to OFF and one or both doors are opened. If the key is turned to OFF and no doors are opened, power will be turned off after approximately 10 minutes.
Possible Causes
- circuit 7-AJ7 (YE/RD) open
- circuit 31-AJ80A (BK/OG) open
- REM
- driver window control switch
