DIESEL ENGINE PTO OPERATION:
"AUXILIARY" POWERTRAIN CONTROL MODULE
The Auxiliary Powertrain Control Module (APCM) commands the Electronic Engine Control
(EEC) module to increase the idle speed during PTO operation. The APCM controls engine
speed from 1300 to 2500 RPM.
The Auxiliary Powertrain Control Module is a seperate option, it does not come standard with a
PTO capable transmission, and is for 7.3L diesel applications only.
Intended for stationary use only, and in stationary operation the PTO requires an engine idle speed
of 1300 RPM. During stationary PTO operation on the 7.3L diesel, the EEC increases the idle to
1300 RPM automatically.
During stationary PTO operation, the Torque Converter Clutch (TCC) engages once the RPM
reaches 1200-1300 RPM.
The following conditions must be met before the idle speed is increased:
1. Parking brake must be engaged for all applications.
2. No hydraulic brake actuation.
3. Accelerator pedal must be in the idle position.
4. Vehicle speed must be zero MPH.
5. Brake lights must be functional.

CHARGE PROTECTION
Charge Protection is used for maintaining battery charge.
In Charge Protection mode, the battery voltage is monitored and the
engine idle speed is increased as necessary, so the battery charge is
maintained as required.
Charge Protection can be activated from in-cab and can be
programmed to activate automatically on engine start-up.
RPM CONTROL
RPM Control is used for
RPM Control mode can be
activated from in-cab and
can be programmed to

The programmable speed
presets range from 1300 to
This is the recommended
method of elevating idle
speed for PTO operations.
