SMART PTO System
5376000192
1-2
SECTION 1 - OPERATION AND
TROUBLESHOOTING
1.1 GENERAL
This vehicle is equipped with Jerr-Dan’s SMART PTO System. It consists of a clutch
shift PTO mounted on the Ford 6R140 TorqShift™ transmission, and controlled
by Jerr-Dan’s SMART PTO Controller. The SMART PTO System is designed to
provide the hydraulic power that your towing and recovery operations require, while
protecting the PTO and transmission from damage.
1.2 OPERATION
To operate your PTO turn on the switch marked as the PTO switch. The SMART
PTO System will automatically determine which mode to engage and send the
proper signals to Ford’s computer to turn on the PTO. With the parking brake
engaged the PTO will enter Ford’s Stationary Elevated Idle operating mode. With
the parking brake disengaged the PTO will enter Ford’s Mobile Mode allowing you
to use the PTO while moving the wrecker below 10 MPH. The PTO switch will also
turn on power to any wired or wireless remotes that may have been supplied with
your wrecker.
To turn off your PTO, simply turn off the switch marked as the PTO switch. The PTO
will disengage, the remote controls will turn off, and any high idle operations will
cease.
1.3 TROUBLESHOOTING
If you exceed a vehicle speed of 10 MPH or 1500 RPM’s while the PTO is engaged
it will automatically disengage and remain disengaged until the speeds fall below
the set thresholds.
If you will be using the PTO without moving the truck, it is advised that you engage
the parking brake to initiate the Stationary Elevated Idle mode. Otherwise, the PTO
may time out and disengage; to re-engage turn the PTO switch off and back on
again.
If any of the enable or disable conditions required by Ford’s system are not met,
then you will have to turn off the PTO switch and turn it back on when the conditions
required by Ford are met again. For a list of the enable and disable conditions please
reference Ford’s bulletin Q-256.
