Using the Onboard Diagnostic Lamp
Machines with wireless hand held remote control (Models 44552, 44552TE, and
44553) have a diagnostic light located on the control tower below the hour meter.
The diagnostic light is an output of the Toro Electronic Controller (TEC) that
indicates normal machine operation or the presence of active machine faults.
After you turn the key to the R
UN
position, the diagnostic light illuminates for 5
seconds, turns off for 5 seconds, and then flashes until you start the engine with
the key switch or push a button on the handheld remote.
The diagnostic light will flash rapidly if no signal from the hand held remote has
been received within 10 seconds of setting the key switch to the R
UN
position,
if the hand held remote is out of range, has low batteries, or is not associated
to the RF2CAN module. The diagnostic light should illuminate while a button
on the hand held remote is pressed.
If the key switch is set to the R
UN
position and the diagnostic light turns on for 5
seconds then starts flashing rapidly (with or without a pause) an active machine
fault exists.
