LED ON:

LED FLASHING:
ORANGE
F3E1 Open Thermistor Condition Continually monitor temperature sensor for an invalid
resistance value based on the thermistor reading value out
of the range of 35.42kΩ (32°F/0°C) and 719Ω (212°F/100°C).
This error will show if reading more than 35.42kΩ for more
than 30 seconds.
1. Review the ambient temperature of the room; if the
temperature of the sensor is less than 32°F (0°C), the
error will remain.
2. Verify the wire harness connection. Any open
connection will create a resistance higher than 35.42kΩ
and the error will remain.
3. Reset the ACU by unplugging the SWASH™ system for
more than 5 seconds.
4. Enter the service diagnostics mode (see page 2) and
review the operation of the thermistor.
5. Verify the resistance value of the thermistor (J3-5 to J3-
6); if it is open or shorted, replace the thermistor.

F2E2 Shorted Thermistor Condition Continually monitor temperature sensor for an invalid
resistance value based on the thermistor reading value out
of the range of 35.42kΩ (32°F/0°C) and 719Ω (212°F/100°C).
This error will show if reading less than 719Ω for more than
30 seconds.
1. Review the ambient temperature of the room; if the
temperature of the sensor is more than 212°F (100°C),
the error will remain.
2. Verify the wire harness connection. Any shorted
connection will create a resistance lower than 719Ω
and the error will remain.
3. Reset the ACU by unplugging the SWASH™ system for
more than 5 seconds.
4. Enter the service diagnostics mode (see page 2) and
review the operation of the thermistor.
5. Verify the resistance value of the thermistor (J3-5 to J3-
6); if it is open or shorted, replace the thermistor.

F2E1 Shorted Key Event If the control detects an invalid key press (one or more keys
pressed for more than 5 seconds), the UI will generate an
error code (F2E1) to the ACU.
1. Disconnect the WIDE Connector of the UI and reset the
SWASH™ system by unplugging the power for more
than 5 seconds. By doing this, the capacitive buttons
will recalibrate.
2. Make sure that the UI PCB Assembly is not affected by
extreme ambient conditions like temperature (185°F
[85°C] max.) and humidity (95% non condensate).
3. Verify 5V input from WIDE connector between lines
P1-1 and P3-1.
4. Inspect the keypad area to confirm that there are no
liquids, moisture, or any other foreign materials on the
capacitive button area.
