5.8 Troubleshooting Loup III System
Solution: With the system turned on,
go the sensor that is not communi-
cating. There is a LED on each sensor
(except the multilevel bin sensor). If
it is flashing slowly (1 flash every 2-3
seconds) that indicates that power
and ground are connected but the
sensor wire is not. The power wire
is +12 volts and is white. It is in the
“A” position on the connector. The
Ground wire is black and is in the “B”
position on the connector. The sensor
wire is the green wire and is in the
“C” position on the connector. If the
LED is not flashing, unplug the sensor
from the harness and plug it back in. If
the LED flashes momentarily, power
is present and the sensor is faulty. If
the LED does not flash at all check
power at the connector. The user
should measure 12 volts between the
white and black wire. If so, the sensor
is faulty, if not, the harness is faulty. All
the white wires on the MUX harness
are connected in parallel, all the black
wires are in parallel, and all the green
wires are in parallel. The user can
measure continuity be-tween any of
the “A”, “B”, or “C” connections on
the MUX harness.
MUX Sensor is not recognized at power up. This will include the ground speed,
fan, and bin level sensors
Possible causes: Harness wiring is faulty or the sensor is defective.
