F6E1 WIDE Communication The failure will be shown if: Communication
• The ACU has not received a valid WIDE serial
communication message within 30 seconds.
• The ACU has detected continuous problems with
messages transmitted over the WIDE bus.
• If communication is resumed at any time, the display
will function normally.
1. Check the wire harness connection between the ACU
and the UI, and measure continuity between all wires.
2. Make sure that the UI PCB Assembly and the ACU
board are not affected by extreme ambient conditions
like temperature (185°F [85°C] max.) and humidity
(95% non condensate).
3. Reset the SWASH™ system by disconnecting the power
for more than 5 seconds.
4. Verify 5V output from the WIDE connector between
lines P1-1 and P3-1 and the P19 connector.
5. Enter the service diagnostics mode (see page 2) and
review the operation of the thermistor.

F1E1 Microcontroller Fault If a corrupted microcontroller or communication error has
occurred, the ACU will generate this error code.
1. Review input voltage from lines P12 and P9. It should
be 120 VAC/60 Hz.
2. Make sure that the ACU board is not affected by
extreme ambient conditions like temperature (185°F
[85°C] max.) and humidity (95% non condensate).
3. Remove the ACU board from the plastic chassis and
perform a visual inspection of the back of the board.
4. Verify 5V and 12V output on the P19 connector
between pins P19-2 and P19-3 for 5V, and P19-1 and
P19-3 for 12V.
5. If no voltage is detected in step 4, replace the ACU.
