7.8 Troubleshooting Loup III System
1. MUX Sensor is not recognized at power up. This will include the ground
speed, fan, and bin level sensors
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 the white wire. 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 lights momentarily,
power is present and the sensor is
faulty. If the LED does not light at all
check power at the connector. You
should measure 12 volts between
the white and black wire. If you do,
the sensor is faulty, if you don’t 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. You can measure continuity
be- tween any of the “A”, “B”, or “C”
connections on the MUX harness.
Possible causes: Harness wiring is faulty or the sensor is defective.
