Condition/Concern
2321545
In rare cases, customers may complain that the driver's power seat is inoperative and/or the SIR light is coming on
intermittently. When diagnosing the vehicle, DTC's B0014 and/or B0015 may be found in the SDM. The "PWR SEAT
LT" fuse may be open in the underhood fuse block. This may be caused by a wire harness getting pinched under the
driver's seat, between the seat frame and the power seat motor (see picture above). This concern happens when the
seat is moved to the up position. This is applicable for both 4 and 8 way power seats.
