Power and Ground

The Memory Seat Fuse (P115) applies battery voltage to retain the memory Circuit of the Memory Seat ECU (Z146) at all times. Voltage to operate the seat motors (M126, M127, M128, M129) and the mirror actuators (M115, M123) is supplied to the Memory Seat ECU from fuses F D5 and F D6. The Fusible Link (P119) supplies voltage to fuses F D5 and F D6 whenever the Driver Seat Relay (K113) is energized. The relay is energized when the driver's door is open. causing the Driver Door Switch (X118) to ground the relay's coil, or when the ignition is in position 2, causing the Passenger Seat Relay (K131) to ground the Driver Seat Relay. The Memory Seat ECU is grounded at ground E301 through the B wires.
