Load C - The power output to be connected to the rear sofa controller.
Ground - The ground for the Auto-Net 440 ONLY. This terminal is not designed as
ground for the motors of the power seats. A wire with a ring terminal is included and
can be used as the ground for the Auto-Net 440. If the spade terminal is used instead
of the wire/ring terminal, the wire/ring should be cut and discarded.
SERVICE
Tools Required: VoltMeter, Two (2) #1156 lamps connected in parallel.
Problem: None of the seats are functional.
Troubleshooting: Measure for voltage between Auto-Net 440 “Ground” and “Battery”.
If no voltage is present check fuse at fuse block or bad wiring. Verify Auto-Net 440 is
properly grounded.
If 11.0 - 14.5 volts is present, disconnect wires from LOAD A, LOAD B, and LOAD C on
the Auto-Net 440. Measure for voltage between ground and each LOAD pin. If 11.0 -
14.5 volts is present, reconnect one wire at a time and measure voltage. If all three
LOAD pins still have 11.0 - 14.5 volts after all wires are connected, troubleshoot wiring
and motors of seats. If the voltage is not present after the wires are reconnected, check
for a short or current draw on one of the LOAD pins.
If the LOAD wires are disconnected, there is 11.0 - 14.5 volts measured between
GROUND and BATTERY of the Auto-Net 440, and no output voltage on the LOAD
pins, replace the Auto-Net 440.
Note
Even though the Auto-Net 440 shuts off power to the passenger seat and sofa, there
should always be an output voltage from LOAD A.
Problem: Passenger Seat or Sofa stop working when the driver seat is on.
Troubleshooting: This is the normal operation of the Auto-Net 440.
Problem: Not all seats are functional.
Troubleshooting: Without any seat operating, measure for presence of 11.0 - 14.5
volts on each LOAD pin. If voltage is present, activate power seat or sofa. Verify
voltage is still present for that particular LOAD pin. Check motor, switch, or wiring for
seat.
If no voltage is present on one LOAD pin, disconnect LOAD wires. Measure for voltage
between ground and each LOAD pin. If 11.0 - 14.5 volts is present, reconnect one wire
at a time and measure voltage. If all three LOAD pins still have 11.0 - 14.5 volts after all
wires are connected, troubleshoot wiring and motors of seats. If the voltage is not
present after the wires are reconnected, check for a short or current draw on one of the
LOAD pins.
If the LOAD wires are disconnected, there is 11.0 - 14.5 volts measured between
GROUND and BATTERY of the Auto-Net 440, and no output voltage on the LOAD
pins, replace the Auto-Net 440.
