TROOPER/ DTC P1589

1998 Isuzu Bighorn

Electrical problem
1998 Isuzu Bighorn 4 cyl Four Wheel Drive Automatic 180000 miles

Please, help me in determining the way how to fix the problem. Scanner and OBD shows code P1589.
Asit's been told in Service Manual I checked fuse 10A, checked connectors at ECM. All are in good shape.
Where to dig to?
