Reactivating Optimized Idle
If the hood is opened or the vehicle is put into gear
while Optimized Idle is running, the system will enter
a safety loop and a pop-up will appear. See
Fig. 13.6. Restoring operating conditions (e.g. clos-
ing the hood or setting the transmission in neutral)
and performing a key cycle will allow you to reacti-
vate Optimized Idle.

Power Takeoff (PTO) Governor
WARNING
To avoid injury, do not install a PTO that is not
Detroit Diesel approved onto a Detroit
™
Trans-
mission. Use of a non-Detroit Diesel approved
PTO with a Detroit Transmission could result in
unintended operation which could lead to severe
personal injury.
Engine power takeoffs (PTO) tap into engine power
to run auxiliary devices, such as hydraulic pumps
that power additional equipment. The following are
general guidelines for operating a PTO.
1.
Set the parking brake and put the transmission in
neutral.
2.
Press the dash PTO switch. Release the switch
when the light begins to blink.
When the light illuminates steadily, the PTO is
engaged and ready to operate. In stationary
mode, the vehicle must remain in neutral with the
parking brake set.
3.
To activate mobile mode, shift from neutral to
reverse, 1st, or 2nd gear. The clutch will open
and the PTO will disengage for a moment.
4.
Touch the accelerator pedal to close the clutch
and engage the PTO in mobile mode. The PTO
