each time. If the safety system does not operate as described

Using the SCM to Diagnose System

Problems

The machine is equipped with a standard control module

(SCM) monitoring system that tracks the function of various

key systems. The SCM is located under the seat.

On the face of the SCM are 11 LEDs that illuminate to

indicate various system conditions. Seven of these lights can

be used by the operator for system diagnosis. Refer to Figure

13 for a description of what each light means. For details

on using the rest of the SCM functions, refer to the Service

Manual, available through your Authorized Toro Distributor.

1. High temperature shutdown—the engine temperature has
