Escape 4WD V6-3.0L VIN 1 (2005)
B2-B6
Normal Operation
The horn relay is controlled by the horn switch. The horn relay is grounded through the horn switch by circuit 6 (YE/LG). When the horn switch is
pressed, the horn relay control circuit 6 (YE/LG) is grounded through circuit 57 (BK). The relay is then closed causing B+ voltage to be applied to
circuit 1 (DB), sounding the horns. The SJB can also supply a ground for the horn relay coil.
