Diagnostic Lamp
The Ultra Sonic Boom System includes a diagnostic
lamp that displays the status of the sonic boom system.
The diagnostic lamp is located on the upper Operator’s
console (Fig. 10).
When the ignition switch is moved to the ON position
and the Ultra Sonic Boom System electrical system is
ON and functioning properly, the diagnostic lamp will be
illuminated for approximately three (3) seconds and
then will turn off. The diagnostic lamp should remain off
during normal sonic boom operation.
If the sonic boom system Toro Electronic Controller
(TEC) controller detects an electrical system malfunc-
tion (fault) during operation (e.g. there is no signal com-
ing from a boom sensor), the affected boom will raise
briefly and then stop. The sonic boom light (in sonic
boom switch) will begin to flash slowly and the diagnos-
tic lamp will flash rapidly. The diagnostic lamp will stop
flashing and will automatically reset when the ignition
switch is turned to the OFF position. The fault, however,
will be retained in controller memory and can be re-
trieved by your Toro Distributor.
If the diagnostic lamp does not illuminate when the igni-
tion switch is turned to the ON position, possible causes
are:
The diagnostic lamp (or circuit wiring) is faulty.
TEC fuse(s) are faulty.
The TEC is faulty.
