Page 3: System Description
Section 1 SYSTEM DESCRIPTION The Auxiliary Idle Control Module, also called Auxiliary Powertrain Control Module (APCM), is for use in Light Trucks equipped with 7.3L DIT Diesel engines. Each kit includes an Auxiliary Idle Control module, wiring harness, mounting bracket and hardware, operator's card, and this instruction booklet. -

Page 5: Charge Protection Mode
CHARGE PROTECT Section 2 CHARGE PROTECTION MODE Charge Protection is used for maintaining system voltage. In Charge Protection mode, the system (battery) voltage is monitored and the engine speed, in RPM, is increased so the voltage is maintained and battery charged as required. Charge Protection mode can be activated from in- cab, remotely, and can be programmed to activate automatically on engine start-up. -
Page 6: Remote Usage
CHARGE PROTECT Step 2 Activate Automatic Charge Protection Mode. With Automatic Charge Protection programmed, the engine speed will be elevated within a few seconds after programming is exited and the vehicle's enabling conditions are met. It is not required to press any additional keys on the module for activation. -
Page 7: Rpm Control Mode
CONTROL Section 3 RPM CONTROL MODE RPM Control is used for elevating idle speed. In RPM Control mode, the engine speed can be controlled between 1200 and 2500 RPM. There are four (4) RPM memory settings, manual (up/down) RPM Control, and "Power Up" or Automatic RPM Control. There are also two remote inputs available for on/off RPM Control and adjustable vernier RPM Control. -
Page 8: Automatic Operation
CONTROL Section 3.2 AUTOMATIC OPERATION - RPM CONTROL Note that Automatic or "Power-up" operation can function only in vehicles equipped with Automatic Transmissions. With Automatic RPM Control programmed, the engine speed will be elevated to Memory #1 within a few seconds after the vehicle's enabling conditions are met. -
Page 9: Custom Rpm Remote Usage
Section 3.4 CUSTOM RPM CONTROL Custom RPM Control allows the user to elevate and adjust the engine speed from a remote location on the vehicle. Inputs are provided in the wiring harness for an electrical vernier potentiometer-type input. Correct installation and programming is required for proper operation. -

Section 3.5 AUTOMATIC OPERATION - CUSTOM RPM CONTROL Automatic Custom RPM Control allows the user to elevate the engine speed automatically, and also adjust the engine speed from a remote location on the vehicle. Inputs are provided in the wiring harness for an electrical vernier potentiometer-type input. -
Page 11: Pto Control Mode
CONTROL Section 4 PTO CONTROL MODE PTO Control is used for electrically actuating a 12V PTO solenoid. The PTO Control key activates a discrete high side driver in the APCM to power up an auxiliary load, such as a Power Take-Off, electric clutch, or other implement. When the application requires the PTO to turn on and run at an elevated engine speed, there is an option to do this called PTO/RPM LINKED. -
Page 12: Pto Lower Limit (Engagement)
Section 4.2 PTO CONTROL WITH MAXIMUM ENGAGEMENT PROTECTION "Maximum PTO clutch engagement protection" can be achieved by utilizing the PTO lower limit on the APCM. The PTO output driver will not be allowed to turn on whenever the actual engine speed exceeds the programmed lower limit. -
Page 13: Pto Upper Limit (Overspeed)
CONTROL Section 4.3 PTO CONTROL WITH OVERSPEED PROTECTION "PTO overspeed protection" can be achieved by using the upper disabling engine limit on the APCM. The PTO output driver will be turned off whenever the actual engine RPM exceeds programmed upper limit. Keep in mind the RPM values are engine speeds and proper conversion to PTO speed is necessary (refer to table below). -
Page 14: Pto Linked With Rpm Control
Section 4.4 PTO LINKED WITH RPM CONTROL When PTO Control is linked with RPM Control (PTO/RPM LINKED), the PTO output is activated and engine speed is elevated in conjunction with each other. When the RPM Control is commanded off, the PTO output will also turn off. -
Page 15: Pto Linked With Custom Rpm Control
Section 4.5 PTO LINKED WITH CUSTOM RPM CONTROL When PTO Control is linked with Custom RPM Control (PTO/CUSTOM RPM LINKED), the PTO and Custom RPM Control operate together. This feature requires programming and remote switch installation. This feature is useful for applications when it's necessary to turn on the PTO and elevate idle from a remote location on the vehicle. -

Page 19: Installation
Section 6 INSTALLATION This section describes the installation procedure for the additional remote circuits available on the Auxiliary Idle Control Module. The Installation Instruction sheet in the kit describes the set-up of this module to the vehicle, including mounting bracket. Locate the mating 4-pin connector under the driver's side instrument panel and connect. See Section 9.2 for connector pin-out. - Page 20 Section 6.1.2 Custom Switch Installation Custom Remote RPM Control requires a potentiometer type input. The potentiometer or other type of resistor network, is used to adjust the engine speed by providing a voltage between 0.5V and 4.5V to the module. For remote activation, it is recommended that a Remote FORD switch is installed as described above to activate and deactivate Custom RPM Control.

Page 25: Pto Control High Side Driver Output
RPM programming mode allows the user to adjust two ramp rates. The default settings are appropriate for most idle control applications. Table 9.3.2 shows the rate of change in RPM for both ramp rates. The first is the initial ramp up rate (∧RMP), which is how fast the engine ramps up to the desired speed. For PTO applications, a slower initial ramp up rate may be beneficial for clutch durability.
