COMMUNICATION ERROR
PARTS THAT MAY BE NEEDED

ERROR DETAIL: COMMUNICATION ERROR
BETWEEN CONTROL MODULE & DISPLAY INTERFACE ASSEMBLY
If communication between the ignition board and the display board is
not established within 3 seconds of power-up, an error will be displayed.
After communication is established, if it is lost for 30 seconds, the er-
ror will be displayed. The error code will be cleared upon a valid data
exchange between boards..
DIAGNOSTIC SEQUENCE
A. Power down heater and re-power. This is similar to rebooting a com-
puter.
B. If rebooting does not solve the problem, inspect the display interface
wiring. Ensure the display interface plug is securely attached to the
control module.
C. If steps A & B do not resolve the CE error, the control module and/or
display interface assembly are defective and must be replaced.
