Toro Electronic Controller (TEC)
Multi Pro 5800 machines with serial numbers above
316000000 use a Toro Electronic Controller (TEC) to
manage machine electrical functions. The TEC is a mi-
crocontroller that monitors the condition of various ma-
chine switches and sensors (inputs) and directs
electrical power to control appropriate machine func-
tions (outputs) based on the state of the inputs. Commu-
nication between the Toro controller, the InfoCenter
Display, and in the case of Gasoline engine powered
units the Kubota engine controller, is provided by a CAN
bus network. The status of inputs to the controller as well
as outputs from the controller can be monitored with the
InfoCenter Display (see InfoCenter Display − Diagnos-
tics in this chapter). The TEC controller is attached to the
left side of the control console frame (Fig. 1).
IMPORTANT: Before performing any welding on the
machine, disconnect the battery cables from the
battery, disconnect the wire harness connector
from the Toro Electronic Controller and disconnect
the terminal connector from the alternator. These
steps will prevent damage to the machine electrical
system.
