Diagnostic Lamp - Toro Multi Pro 1200 Service Manual

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 dash panel (Fig.
9).
When the ignition switch is moved to the ON position
and the Ultra Sonic Boom System electrical system is
functioning properly, the diagnostic lamp will be illumi-
nated 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 TEC controller detects an elec-
trical system malfunction (fault) during operation (e.g.
there is no signal coming from a boom sensor), the af-
fected boom will raise briefly and then stop. The sonic
boom light (in sonic boom switch) will begin to flash
slowly and the diagnostic lamp will flash rapidly. The
diagnostic lamp will stop flashing and will automatically
reset when the ignition switch is turned to the OFF posi-
tion. The fault, however, will be retained in controller
memory and can be retrieved at a future time (see Re-
trieving Fault Codes below).
If the diagnostic lamp does not illuminate when the igni-
tion switch is turned to the ON position, possible causes
are:
D The loopback connector (6 pin connector) is not
connected to the machine wire harness (Fig. 10).
The loopback connector is near the TEC controller
on the mounting plate under the dash panel.
D The diagnostic lamp (or circuit wiring) is faulty.
D TEC controller fuse(s) are faulty.
D The TEC controller is faulty.
Check electrical connections, controller fuses and the
diagnostic lamp to determine malfunction. Make sure
that the loopback connector is secured to the wire har-
ness connector during machine operation.
