Standard Control Module - Toro Groundsmaster 4500-D Service Manual

Standard Control Module

Groundsmaster 4500--D and 4700--D machines with
Serial Numbers above 230000000 are equipped with a
Standard Control Module to monitor and control electri-
cal components required for safe operation. This Mod-
ule is located under the console cover.
Inputs from the neutral, parking brake, PTO, start (igni-
tion), and high temperature switches are monitored by
the Module. Output to the PTO (deck drive solenoids),
fuel pump, and engine run solenoid are controlled based
on the inputs received by the Module.
The Standard Control Module does not connect to an
external computer or hand held device, can not be re--
programmed, and does not record intermittent fault
data.
The Standard Control Module can be used to check op-
eration of machine switches by monitoring the LED's of
the module. If a Module LED does not illuminate (e.g. the
in seat input LED does not illuminate with the seat occu-
pied and the ignition switch in the run position), testing
of the switch and circuit wiring would be required.
Refer to the Operator's Manual for operation and trou-
bleshooting of the Standard Control Module.
