Standard Control Module Logic Chart (2WD Machines)
Each line of the following chart identifies the necessary
component position (INPUTS) in order for the Standard
Control Module (SCM) to energize the appropriate
OUTPUTS for machine operation.
Example: To start the engine with an operator in the
seat, when the ignition key is in START, the traction con-
trol pedal is in the neutral position and the parking brake
is not applied, engine components and the engine start-
er will be energized.

IMPORTANT: During machine operation, if the PTO
shuts down and the console temperature warning
light is illuminated, avoid shutting off the engine.
Under this condition, the operator should push the
PTO knob down, slowly drive to a safe flat area,
move the throttle lever to the SLOW position, re-
lease the traction control pedal to the neutral posi-
tion and engage the parking brake. The engine
should be allowed to low idle speed for several min-
utes while it cools to a safe level. Then, the cooling
system should be checked before returning the ma-
chine to service.
