DIAGNOSTICS
AUTOMATIC ELECTRONIC DIAGNOSTIC
The face plate has a self-diagnostic function for the
electrical system (except input power). The face plate
monitors the electronic components and circuitsfor
correct operation. If a malfunc-
tion occurs, an error code ap-
pears in the face plate display.
The chart below shows the error codes that could
appear, and the possible defects for each code.
While an error code appears in the display, all face
plate buttons are inoperable except the SET/CLEAR
button. SET/CLEAR remains operational so the
service person can make the MANUAL ADVANCE
DIAGNOSTICS to further isolate the defect.
POSSIBLE DEFECT
CODE MOST LIKELY ,, '- LESS LIKELY
E - 1 motor inop. / wiring harness or connection to switch / switch / face plate
E - 2, E - 3 face plate
E - 4 face plate / position switch
