Verify Diagnostic Display Output Functions
B. If the output LED’s are on as specified, but the
machine does not function properly, suspect a failed
electrical component, an open in the tested circuit or
a non-electrical problem (e.g. hydraulic component
problem). Repair as necessary.
The Diagnostic Display also has the ability to detect
which output solenoids or relays are energized by the
TECcontrollers.Thisisaquickwaytodetermineifama-
chine malfunction is electrical or hydraulic.
C. If each input switch is in the correct position and
functioning correctly, but the output LED’s are not
correctly illuminated, this indicates a TEC controller
problem. If this occurs, contact your Toro Distributor
for assistance.
NOTE: Anopenoutput(e.g.anunpluggedconnectoror
a broken wire) cannot be detected with the Diagnostic
Display.
