13.0 UART Error
- Wiring harness bad between
power distribution board and main
control board.
- Power distribution board bad
- Main control board failed
- Ohm check wiring harness
- Replace power distribution

- Replace main control board
13.1
Primary Vac
Sensor out of
range low
- Sensor on power distribution
board is bad
- Canister is pressurized
Note:
This fault is caused by faulty
sensors or by actual positive
pressure in the sensor lines.
Although vacuum is negative
pressure, it is displayed as a positive
value on the screen. (i.e. 14 in/Hg)
So a negative pressure is displayed
as a positive value, and a positive
pressure is displayed as a negative
value. With no sensor lines
attached, the sensors should read
very close to zero. If the value
displayed in technician menu does
not change when the sensor lines
are removed, then the sensors are
bad. If it does change, then the
sensors were working properly and
the canister was pressurized. 13.1
and 13.3 will fault if lower than -.3
in/Hg (-.4, -.5, etc). Faults 13.2 and
13.4 will fault if higher than 24 in/Hg.
- Enter technician mode and go
to the level sensor LEVEL DATA
screen.
- Unplug all sensor lines on
power distribution board.
IF:
suction displays a negative
number,
replace the power
distribution board.
suction displays a positive
number ,
then the canister is
pressurized. Find out what is
causing the positive pressure in
the canister.
