1. Introduction
InPower’s SS-FD23 Start/Stop/Elevated Idle Module provides Start/Stop Functions
and an elevated Idle selection. This product is compatible with the 2023 F250-F600. It
is designed to be mounted under the Steering column near the OBDII connector and
the Trailer Brake Controller Module.
Modules come with various modes of control: Start, Stop, and two preset RPM speeds
(one default setting and another selectable).
Note: The elevated idle functions will only operate if the Chassis Ready
Conditions are satised. LED diagnostic indicators are provided to aid in system
troubleshooting. These LEDs are located on the module opposite the connector.
Chassis Ready Conditions typically could be:
• No vehicle speed
• Accelerator not depressed
• Engine up to Operating Temperature
• Shifter in Park
• Service brake not depressed
• Engine running below base idle
• No Diagnostic Trouble Code (DTC). Check Engine light must be off.
• Other hindering conditions will be detailed in the Body Builder’s Guide (www.
eet.ford.com/truckbbas/)

1.1 Interface Selection
This section discusses the interface for the SS-FD23-02
1. The SS-FD23 needs to be located close to the Steering Column so that the
wires that connect to the ignition switch RUN wire (Yellow-Group 1) to the
RUN-IN and RUN-OUT (White-Group 1) can be connected easily. The Start
Signal (Lt. Blue) goes to the START wire from the ignition switch.
2. The connection to the Data Bus via a T-Harness to the Trailer Brake
Controller Module (Page 12) so it needs to be located close to it near the
OBDII connector.
3. ENABLE (Pink, Group 2) is a 12V signal that will enable the SS-FD23 for
operation and turn on the interfaces.
4. RPM1-Gnd Pulse (Tan, Group 2) requires a pulse to Ground to select RPM1,
and a second Ground Pulse to turn RPM1 off (back to RPM STBY - Default).
5. RPM1-12V (Violet, Group 2) requires 12V to enable RPM1, and removing
12V from this line will turn RPM1 off (back to RPM STBY - Default). RPM
Gnd Pulse (Tan) is not available as long as 12V is applied to this line.
6. START/STOP (Brown, Group 2) requires a pulse to Ground to Turn Engine
On, and a second Ground Pulse to Turn the Engine Off. RPM is used to
check Engine Status.
7. The Power Connections are Battery (Red, Group 2) rated at 15 Amps, and
Ground (Black, Group 2) connected to Battery Ground.
8. Outputs
• The PTO Interface is the PTO OUT (Orange, Group 2) 12V (10A Max)
which turns on when SEIC PTO RLY goes to Ground.
• U-IGNITION 12V (Yellow/Red, Group 2) remains on as Engine Stop (5A
Max) is on. Turned ON/OFF when ENABLE is turned ON/OFF. This is
for uptter components needing to remain powered during a shut down
sequence.
• Decoded PARK (Dk Blue Group 2) and PARK BRAKE (White/Black
Group 2) discrete wires are available as discrete wires (GND True).
These reect the current status of the PARK BRAKE and PARK for the
vehicle and are enabled by the RUN (+12V True) line.
(Total for PTO and Ignition 12 should be less than 13A total)
9. SEIC Blunt Cut Wires
• PTO_RLY (Lt Blue, Group 3) - PTO Relay
• PTO REQ1 (Yellow/Green, Group 3) PTO Request
• PTO RPM (Dark Green, Group 3)

2. Installation
2.1 Safety Precautions
This electronic Start/Stop/Elevated Idle product has been designed and manufactured
to meet the intended application requirements and specications. Any modications to
the product or to the installation procedure can be dangerous and will void InPower’s
warranty.
• Read and understand the instructions in this manual and other manuals before
starting the installation.
• Make sure that the vehicle battery power is disconnected during the
installation of the Start/Stop module.
• Reconnect the battery when the system installation is complete.
• Wear appropriate safety equipment, such as protective eyeglasses, faceshield and
clothing when installing equipment and handling the battery.
• Be careful when working near a battery. Make sure that the area is well ventilated
and that there are no ames near the battery. Never lay objects on the battery that
can short the terminals together. If battery acid gets in your eyes, immediately seek
rst aid. If acid gets on your skin, immediately wash it off with soap and water.
• Avoid disconnecting and making connections to the SEIC and PTO with the vehicle
powered.
2.2 Getting Started
IMPORTANT NOTE: Once again! Please obtain the specic SEIC installation
instructions for your vehicle model from Ford. Wire colors and locations may vary
from model to model and even between different years for the same model. The
guide may be obtained from Ford’s Body Builder Advisory Service.
(www.eet.ford.com/truckbbas/)
Carefully disconnect the battery before making any electrical connections.
2.3 Mounting
Mount the SS-FD23-02 module under the dash near the steering column.
2.4 Wiring
First, identify the GROUND Wire (Black, Pin12, Group 2) and connect it to a solid
battery ground prior to any other connections.
Connect the 12V power (Battery, Red, Pin17, Group 2) to a fused battery feed (Battery
still disconnected on the vehicle).
Proceed with connecting the Group1 wires to the Ignition switch (RUN-IN, RUN-OUT,
and START) then connect the Group2 Wires to the Control Interfaces (descriptions
called out in the 2.5 Control Interface section). Also refer to Section 7 Start/Stop Ignition/
BCM/SS-FD23-02 Wiring Page 16.

After termination of all wires, connect the the J1 cable to the SS-FD23.
2.5 Control Interface (Operation)
Determine the combination of two high idle speed modes needed (RPM1 and RPM-
STBY).
The customer needs to supply switches for the ENABLE, START/STOP, and RPM1
modes. These modes are selected by wires in the Group 1 bundle.
The RUN-IN line provides power for the SS-FD23 and if not present, places the unit in
an ultra low power state (micro Amperes).
The RUN-OUT line provides the control for the Body Control Module to indicate
the Ignition is on to the Body Control Module that the vehicle is ready to start (if all
conditions are conducive)
The ENABLE 12V line (Group 2 - Pink Wire) will take the Module out of StandBy when
True. If Ignition is ON but Enable is not True, the SS-FD23 will monitor the Chassis
Data Bus for status, but will not operate the Start-Stop, High Idle functions and
outputs. If Enabled, removal of +12V from this Pin will shut off the High Idle, returning
the engine to running at normal idle, turn off the outputs (except for PARK and PARK
BRAKE), and will place the SS-FD23 in StandBy.
The RPM1 Trigger Gnd Pulse on this Wire (Group 2 - Tan) if in RPM STBY, will
change the system to RPM1. A second Pulse to Ground will change the system to
RPM STBY.
The RPM1 12V on this Wire (Group 2 - Violet) if in RPM STBY, will change the system
to RPM1 as long as 12V is present. Removing 12V will return the unit to RPM STBY.
The START/STOP Switch is connected the START/STOP Input Wire (Group 2 - Brown
Wire) to supply a Ground Pulse to Start the Engine (unit will enter into RPM STBY
Mode). A second Pulse to Ground will Stop the Engine. RPM messages are used to
verify Engine Status. The START/STOP LED indicates switch activity.

PTO OUT (Orange Wire - Group 2) provides a connection to the PTO Solenoid
capable of driving up to 10 Amps max (Note PTO OUT and U-IGN should never
exceed a combined current of 13 Amps).
U-IGNITION - 12V Uniterrupted Ignition (Yellow/Red Group 2) is ON whenever
ENABLE it ON and is used for support of uptter components that may need to remain
powered during the engine shut-down sequence.
The Power Connections are Battery (Red wire - Group2) rated at 15 Amps, and
Ground (Black - Group2) connected to Battery Ground.
PTO RLY (PTO Relay) - (Lt. Blue, Group 3) Indicates the PTO Relay is OK to be
engaged. LED Indicator ashes if not OK - Usually indicates problems with Chassis
Ready Conditions.
SEIC PTO RPM (Dk Green Wire - Group 3)
SEIC PTO Req1 (Yellow/Green Wire - Group 3)
3. Operation
When the vehicle is parked and Chassis Ready Conditions are satised, the Start
and Stop Functions and engine idle speed may be controlled by selection of one of the
modes: START, STOP, RPM1 (RPM STBY is ON when ENABLE is ON, ENG ON is
ON, and RPM1 is OFF). The preset RPM modes may be adjusted via applying +12V or
GND to the gray RPM ADJUST wire (RPM Adjustment Procedure, page 8).
Chassis Ready Conditions:
• No vehicle speed
• Parking brake set
• Shift selector in Park
• Accelerator not pressed
• Service brake not pressed
• Engine running and at Base Idle
• No Diagnostic Trouble Code (DTC). Check Engine light must be off.
NOTE:While the engine is in high idle, should the throttle be deactivated by one
of the Chassis Ready Conditions changing, the engine will return to normal speed.
The throttle will ash the diagnostic LEDs to indicate the cause of the deactivation.
Modes of Operation:
Enable:
Description:
Once the module is powered up by turning on the Ignition, it waits in StandBy mode
until a steady 12V enable signal is detected on the ENABLE input (Pink - Group2).
Then the module detects if Engine is ON or OFF via the Data Bus Engine RPM
message and goes to RPM-STBY if the Engine is ON. If the 12V enable signal is
removed the module returns to the low power mode after turning off all outputs and
all LEDs except the BUS ON (showing Bus trafc), and if the Engine is ON and High
Idle is selected, it will also return to standard Idle speed.
If the RUN is on, then the PARK and PARK BRAKE Outputs will be present.

Engine Off/Start Section:
If the engine is OFF, the RUN is ON, and the ENABLE line at +12V, the module waits for
an open circuit to ground transition on START/STOP (Brown - Group2) input and then
runs the remote engine start routine. The START output will only be activated if the Park
Brake status and the Shift Park position are both True. If a RPM Messages show engine
activity, the module will transition to the Engine On routine. If RPM Messages do not
indicate operation within 5 seconds, the module will return to engine OFF state.
Enable: Steady +12V on Enable (Pink-Group 2) Enables Module and
Outputs
Start/Stop: A Pulse from Open to Gnd (Brown - Group 2) starts the
Engine if the Engine is Off and the Chassis Ready
Conditions are met, if Engine running, additional Pulse to
GND will Stop Engine.
Engine On/High Idle Section:
After a 5 second delay for the engine rpm to stabilize (via RPM messages), the PTO
REQ1 and PTO RPM outputs are turned on. The module now waits on an open circuit
to ground transition on the PTO RLY input indicating the SEIC is active. The module
now turns on the PTO output and the engine rpm is increased to the RPM STBY
speed.
When the unit is on, the default RPM will be RPM STBY. If an open circuit to ground
transition is detected on RPM1 input (Tan, Group2), the engine rpm is changed to the
RPM1 set point. If another open circuit to ground transition is detected on the RPM1
input, the engine rpm is changed back to the RPM STBY speed.
Preset RPM Modes
Activation:
When Off: Enable: Apply +12 V to Enable (Pink Wire - Group2)
Enables Unit
Engine is OFF: A GND Pulse on Start/Stop (Brown Wire - Group 2)
Starts Engine and goes to RPM STBY (Default High Idle RPM).
In RPM STBY: Apply GND Pulse to RPM1 (Tan Wire - Group2),
GND Pulse Select unit goes to RPM1.
In RPM1: Apply GND Pulse to RPM1 (Tan Wire - Group2) and the
unit goes to RPM STBY.
Or In RPM STBY: Apply 12V to RPM1 (Violet Wire - Group2),
+12V Select unit goes to RPM1 (locks out use of Tan Wire).
In RPM1: Remove 12V from RPM1 (Violet Wire - Group2) and the unit
goes to RPM STBY.
Deactivation:
In Any Mode: Removal of Enable 12V (Pink Wire - Group 2)
(Engine Running) Disables RPM1 or RPM STBY and Shuts Off High Idle
and goes to standard idle speed.
In RPM1 or STBY: A GND Pulse on Start/Stop (Brown Wire - Group 2)
(Engine Running) Stops Engine (U-Ignition Remains ON)
Default RPM Settings +/- 5% Tolerance (Ford Interface Dependent)
RPM-STBY - approx 870 RPM Gas, 950 RPM Diesel
RPM1 - approx 1200 RPM Gas, 1500 RPM Diesel

Calibration Range: Varies based on vehicle model.
Generally, 900 RPM to 2200 RPM (gas) or 900 to 2800 RPM (diesel)
Both the RPM STBY set speed and the RPM1 set speed are adjustable using the
ADJUST input. Any adjustments made will be automatically stored after an open
circuit is detected on the RPM ADJ input for 5 seconds.
To Calibrate an RPM, Select the RPM and then apply +12V (up) or Gnd (down) to
the RPM Adjust Input, (Lt. Green - Group 2).
RPM Adjustment Procedure:
1. Activate the mode desired for adjustment by Enabling the unit and then running
at the RPM-STBY or by selecting RPM1 with a Gnd pulse on the RPM1 (Tan
Wire - Group 2) Line or alternately by applying 12V to the Violet wire - Group 2
for RPM1.
2. Locate the ADJUST wire (Lt Green - Group 2) in the harness. Apply +12V
to this wire to raise the RPM or to GND the wire to lower the RPM. For each
second that +12V is connected to the RPM ADJUST wire (Lt Green, Group2),
the RPM will increase by 50 RPM per second. Likewise, if the RPM ADJUST
wire is tied to GND, the RPM will decrease at a rate of 50 RPM per second.
Releasing it from either +12V or Ground will steady the RPM.
Note: For each bump of less than a half second, the RPM will move by 25RPM up or
down (depending on whether Adjust is bumped to +12V or GND). If connected to +12V
or GND for a second (or more) it will increase by 50RPM for each second the Adjust is
connected to the voltage.
The new RPM Value is automatically saved after Five (5) Seconds
Note 1: A minimum of 910 RPM is recommended for PTO to activate.
Uninterrupted Ignition Output:
During the engine start and stop routines, the ignition run feed is turned off which
also turns off the ignition power to the uptter switches. The Uninterrupted Ignition
Output (Yellow/Red Wire, Group 2) provides a 12V output for equipment that needs
a continuous ignition signal. This output is rated at 5A.

5. Installation and Troubleshooting
5.1 Please refer to the Throttle Selector Guide found on our website for the most up-
to-date compatibility information.
(www.inpowerdirect.com/electronicthrottlecontrols_selector.php)
5.2 Check all wiring and make sure all connectors are plugged in rmly.
Refer to the Harness Wire Chart in Section 4 Mechanical, and check that wires are
connected to appropriate inputs and outputs.
Ford vehicle wire colors and locations may vary substantially between different models
and even different model years. Please obtain and consult the SEIC information for
your specic vehicle. Documentation may be obtained from Ford’s Truck Body Builder
Advisory Service (www.eet.ford.com/truckbbas/).
5.3 A series of 8 LEDs on side of the module provide diagnostic information for
troubleshooting purposes. The LEDs are labeled and correspond to RPM modes and
safety interlocks necessary to bring the vehicle to high idle. If no LEDs are illuminated,
the unit does not have power from RUN.

5.4 While engine is in high idle, if one of the Chassis Ready Conditions changes state,
the engine will return to factory idle. The unit then will ash the diagnostic LEDs (PTO
RLY, PARK, or PARK BRAKE) to indicate the cause of the high idle deactivation. Then,
once conditions are restored, after a ten second delay, it will return the vehicle to the
preset high idle speed. This feature may be used to troubleshoot intermittent problem.
