PINPOINT TEST I: THE ONE-TOUCH DOWN FEATURE IS INOPERATIVE


Test I1-I2:






Test I3-I5:






Test I6-I8:






Normal Operation
The FEM powers circuit 7S-AJ16 (YE/BK) to the driver window control switch. When the FEM detects a ground on circuit 7S-AJ16 (YE/BK), it powers and grounds the appropriate driver window motor circuits in order to accomplish the commanded one-touch down operation of the driver window.

DTC B1398 will set if the FEM senses an open, short to battery or short to ground on circuit 7S-AJ16 (YE/BK).

Possible Causes
- circuit 7S-AJ16 (YE/BK) open, short to battery or short to ground
- driver window control switch
- FEM
