The resistance ladder circuit acts as a potential
divider. The PCM has an internal reference
voltage of 5 volts. Current passes through an
internal 320 ohm resistor (not shown above) prior
to passing through the resistance ladder. There
is also a (second) 220 nF capacitor internally
within the PCM between the 320 ohm resistor &
ground (not shown above) & this is to reduce
EMC effects.
With all the switches open there a total resistance
in the green/white loop of approx 4330 ohms &
this corresponds to normal driving operation (as
does short circuit – the condition prior to the loop
being cut).
Starting from the right of the diagram, when the
key switch is closed only 2110 ohms is in the
circuit & the PCM software recognizes this as the
RPM mode being armed & ready for operation
(Key switch closed = on, open = off). A key switch
is recommended in this position for a couple of
reasons:
•If the control box is located externally on the
vehicle, the requirement for a key avoids any
passers by being able to put the vehicle into
RPM Speed Control mode by simply pressing
a button.
•Using a key switch where the key can be
removed in either the ‘on’ or ‘off’ condition
could be used as an aid to anti theft. If the
operator uses a key to put the vehicle into
RPM Speed control mode & then removes the
key, then the vehicle cannot quickly & easily
be taken out of RPM speed control mode. If
a foot pedal is pressed while in either the 3
speed or variable speed modes, the vehicles
engine will stall & therefore the vehicle can not
easily be driven away & stolen.
When in 3 speed mode pressing any of the
middle 3 switches (with the feature armed) results
in the engine RPM jumping to the corresponding
RPM value held in memory (defaults of 1100, 1600
or 2030rpm) for the 3 switch positions. A second
consecutive press of the same button returns to
normal idle.
When in variable speed mode the same 3 buttons
act as ramp up, ramp down & return to idle
selections respectively.

The software in the PCM responds to the change
of state, so it is recommended that these 3
middle switches be non-latching push button
micro switches. When going from idle to an
elevated RPM the execution of the command
will occur as the button is released. When going
to idle the execution of the command occurs as
the button is pressed.
The final button (the one on the left in Fig. 4) acts
as an ‘emergency’ vehicle engine stop. It is
recommended that this be a red & oversize
non-latching micro switch button. The execution
of this command will occur as the button is
pressed.
All wiring connecting the PCM to the resistance
ladder control box should be shielded & twisted
(33 twists / m) to reduce EMC effects
All resistors should have a tolerance of +/- 5% or
better
Switch contact, connectors & loom (loom
between the green/white wires & the control
box) total resistance must be no greater than 5
ohm max.
The PCM to resister ladder control switch box
loom should not come within 100mm of any other
harness, especially any carrying heavy loads.
Designs which do not require all the button
switches must still have the complete resistor
network with the switches positioned correctly
within the network.
The resistance ladder is acting as a potential
divider
The 220 nF capacitor is used in the circuit to
reduce EMC effects on the system
A suitable two way quality connector should be
used to connect the control box to the two
green/white wires
How to change the default settings
By default, when the feature is first enabled
(either via factory order or via dealer IDS tools),
it will be set to the 3 speed mode of operation
with preset RPM values of 1100, 1600 & 2030rpm
for the 3 speeds.
There are two methods by which these defaults
can be modified:
1.via the IDS diagnostics system at a Ford dealer
(there may be a charge for this)
2.via an inbuilt vehicle ‘learn mode’
Via the IDS system the mode of operation can
freely be changed between any of the 3 modes
of operation, the feature can even be turn off
(disabled). The 3 default RPM speeds can also
be modified.
Via the vehicle ‘learn mode’ the 3 speed mode
& the variable speed mode can be freely
interchanged, however it is not possible to select
the idle up speed mode via the vehicle learn
mode. The 3 default RPM speeds can also be
modified via ‘learn mode’
It is not possible via either method above, to
change the step value of 25rpm per press or the
250 rpm per sec for a held down button, in the
variable rpm speed mode.
Via IDS The RPM Speed Controller menu is under
the tool box tab, then Powertrain, then service
functions, then PCM. The IDS on screen menus
will guide the dealer through the options & setup.
How to enter vehicle ‘Learn mode’
1.Make sure that the RPM Speed controller
switch box is connected but turned off (not
‘armed’)
2.Start the engine (vehicle out of gear & no foot
pedals being pressed, handbrake on)
3.Wait a couple of seconds for the instrument
panel start up diagnostic lights to extinguish
4.Press & release the clutch pedal
5.Press & release the brake pedal
6.Repeat steps 4) & 5) a further four times
(clutch & brake pressed a total of five times
sequentially each)
NOTE: Steps 4) to 6) have to be started within
10 seconds of the engine start
The vehicle should now be in ‘learn mode’
How to Select between modes
1.Enter ‘learn mode’ (see directions above)
2.Arm the RPM speed controller (turn the key
switch to ‘on’)
If the vehicle is already in 3 speed mode (the
initial default):
3.Press & release the brake pedal five times
The vehicle should now be in variable speed
mode. The new settings can be saved & learn
mode exited (see below)
Alternatively
4.Press & release the brake pedal once
The vehicle should now be in 3 speed mode.
The new settings can be saved & learn mode
exited (see below)
Using this method it is easy to change between
these two modes of operation for the RPM
speed controller
NOTE: If the engine stalls out at the initial brake
pedal input then the vehicle was not in, or has
dropped out of ‘learn mode’ & you will have to
restart the procedure.

How to change the 3 pre-set default
RPM values in the 3 speed mode
1.Enter ‘learn mode’ (see directions above)
2.Arm the RPM speed controller (turn the key
switch to ‘on’)
3.Press & release the brake pedal once
4.Press & release the RPM button that requires
re-programming
5.Use the accelerator pedal to rev the engine to
the new desired RPM speed & hold at this
speed (only speeds between 1200 to 3000
rpm can be selected in 3 speed mode)
6.Press & release the same RPM button to reset
the stored RPM speed to the current engines
RPM
7.Release the accelerator pedal
8.Repeat steps 4) to 7) for the remaining RPM
buttons
The 3 RPM speeds should now be
re-programmed to the new RPM speeds. The
new settings can be saved & learn mode exited
(see below)
NOTE: If the engine RPM responds to the initial
RPM button press, then the vehicle has not
entered ‘learn mode’ correctly & you will have to
restart the procedure. If the engine stalls out at
the brake or accelerator pedal inputs then the
vehicle was not in, or has dropped out of ‘learn
mode’ & you will have to restart the procedure.
How to save new settings & exit
from ‘Learn mode’
1.From within the ‘learn mode’ & with the RPM
Speed Control switch box ‘armed’, press the
clutch pedal repeatedly until the engine stalls.
2.Restart the engine & test the new settings,
repeat above procedures if necessary
NOTE: The engine stalling indicates that the
settings should have been saved & the vehicle
has exited from ‘learn mode’. Learn mode
however is very specific that the exact steps are
taken in the correct order & within certain time
limits otherwise the learn procedure fails & it may
take several attempts to get this order & timing
correct & a successful modification from the
default settings.
Some Reasons why RPM speed
Control operation may stop or fail
The RPM Speed control software monitors
vehicle information during operation in RPM
speed control mode & will drop out of RPM speed
control and / or stall the engine should any
adverse signals be detected. For example:
•If the engine temperature becomes too hot
then RPM speed control will stop in order to
protect the engine.
•If the engine oil light illuminates then RPM
speed control will stop in order to protect the
engine
•If the low fuel level light illuminates then RPM
speed control will stop so that the vehicle can
be driven to a refueling point.
•If the vehicle speed exceeds approx 2.5 mph
wile in 3 speed or variable speed modes, then
RPM speed control may stop. RPM speed
control should normally be operated with the
hand brake on, but some uses may require a
low level of vehicle ‘creep’ during RPM speed
control operation. Note that there is no sensing
of the park brake on this version of RPM speed
controller to facilitate this type of operation.
•The software monitors for ‘stuck on’ buttons
on the control switch box, this may result in
RPM speed control being halted. A button that
is held down for too long may be registered
by the software as a ‘stuck’ button.
•The software monitors the foot pedals, if
depressed these may stall the engine if in 3
speed mode or variable speed mode (does
not apply to idle up speed)
•If the control switch box circuitry significantly
exceeds 2110 ohms or there is a short circuit
then RPM speed control will not be possible.
•If a PTO conversion has been attempted on a
vehicle with a non ABS braking system then
RPM speed control will fail due to vehicle
speed being registered via a transmission
speed sensor and / or the need to press the
clutch in order to put the vehicle in gear while
in RPM speed control mode.
4.14.10 Adding Connectors,
Terminals and Wiring
Additional Rear Speakers
NOTE: The connectors on the Instrument Panel
harness (14K024) and the main harness (14401)
are reversed between Left Hand Drive (LHD) and
Right Hand Drive (RHD) vehicles, hence different
sets of terminals/wires are required to cover all
the markets.

For Chassis Cab with tail lift design as described
above it is recommended to use unique body
sub-frame for fixing to Chassis Cab structure. For
connection between sub-frame Chassis Cab
body structure please refer to Figure E74696.
For Chassis Cab with under-slung tail lift load
capacity is up to 1000kg at 1000mm from rear
end of chassis frame to center of load if mounted
and functioning on centre line of vehicle. If
mounted and functioning off center line or at the
side of the vehicle load capacity is reduced to
500kg at 1000mm from side/rear end to center
of load.
Greater off-sets and/or loads require additional
stabilizing equipment such as outriggers or
ground jacks. It is recommended not to increase
vehicle body stress over limit as given by load
factors above. If uncertain please consult your
local national sales representative or the Vehicle
Converter Advisory Service [email protected].
It is the Vehicle converters responsibility to fit a
decal to the converted vehicle stating that the
equipment must not be used without
outriggers/ground jacks in operating position. It
is also the vehicle converters responsibility to
guarantee safe functioning of the equipment.
For hydraulic tail lifts as used for general loading
or more specialized for wheel-chair lifts please
refer to Figure E75874.
5.1.7 Partitions (Bulkhead) - Driver
and Front Passenger(s)
Protection on Van, Bus and Kombi
The following two figures show the standard
bulkhead fixing locations on B-pillar. These are
hexagonal holes for M6 thin sheet rivet type nuts.
The standard range of Ford Regular Production
Option bulkheads can be retro-fitted at these
points.
Conversely a Ford Regular Production Option
bulkheads can also be removed.
Ford Regular Production Option bulkheads do
have a clearance between bulkhead and body
structure to allow natural body flexing and an air
circulation from the cab to the rear load space
for ventilation control.
Air circulation and body flexing must be also given
consideration when engineering an alternative
bulkhead. It is not recommended to restrict
driver’s or passengers’s seat adjustment travel.
It is the vehicle converter’s responsibility to ensure
local current legislation, governing bulkheads and
protective window grilles, is met. It is also the
converter’s responsibility to ensure legal load
constraint requirements if using a non Ford
Regular Production Option bulkhead.

5.7.5 Roof Racks
Roof racks may be fitted to all van, bus and kombi
variants as illustrated in figure E75917, providing
the following is satisfied:
•The carried load does not exceed 100kg (Body
Builder to ensure owner’s hand book identifies
this limitation).
•The carried load does not exceed 300mm
load height (converter to ensure owner’s
information book identifies this limitation).
•The load is evenly distributed (converter to
ensure owner’s information book identifies this
limitation).
•The rack and subsequent carried load is
supported in the roof drip rails irrespective of
rack retaining method.
•The unit load on the roof drip, under worst
case loading, must not exceed 75kg per rack
foot.
•The rack is clamped to the drip rail at six (6)
points per illustration, or alternatively bolted
through the roof panel with minimum six (6)
M8 bolts, self locking nuts and 3mm X 50mm
square spread plates.
•The rack leading edge preferably should not
be located forward of the rear edge of the
driver’s door, or “B” pillar as shown.
Double Cab
The forgoing limitations are based on ensuring
body structure integrity, vehicle handling, braking
and plated axle weights. Such considerations
must also be applied to any double cab
applications, in particular steering, braking and
front axle plated weight and the extra continuous
loads on the “A” pillar, which should not exceed
60 kg total incremental load.
Ensure that the planned loaded vehicle operates
within its designed Center of Gravity condition.

5.11.3 Extended Chassis Frame
General:
•Rear overhang extensions are available as
Regular Production Option.
•Bodies or equipment exceeding the standard
extension length must be supported, please
refer to Figure E74575 low body longitudinal
members or Figure E74576 self-supporting
body structures.
•It is the Body Builder's responsibility to mark-up
the owners’ handbook advising the available
payload. Axle plated weights and maximum
allowable axle mass as shown in this manual
must not be exceeded.
•The vehicle should be planned for uniformly
distributed loads.
5.11.4 Non Standard Rear Chassis
Frame Extension
Extensions longer than the standard Regular
Production Option must comply with the following
guidelines:
•The original rear cross member and or
under-run bar or equivalent must be
repositioned at the end of any altered
extension to meet legislation, please refer to
Figure E74578 Non Regular Production Option
rear chassis frame extensions. Also see.
Refer to: 1.17 Towing (page 54).
(Figure E74854)
•The standard fit under-run bar is bolted on as
shown in Figure E74578 and Figure E74854
as mentioned in previous paragraph.
•The altered extension assembly must include
a cross member adjacent to the end of the
original chassis frame to replace the relocated
under-run bar, see Figure E74577.
•Flat-beds and low bodies built onto Non
Regular Production Option extensions must
have continuous longitudinal members
engineered by the Body Builder or equipment
supplier (please refer to Figure. E74577) to
resolve the worst case moments at rear bump
stop.
•Extensions should be secured to the chassis
frame sandwiched under the rear spring
shackle bracket utilizing the four (4) bolts and
four (4) holes in the rear of the chassis frame,
totaling eight (8) per vehicle side (please refer
to Figure E74578).
•The four (4) rear most existing holes in the
chassis frame must be sleeved with tubes to
prevent chassis frame collapse, refer to Figure
E74578.
•The spacer tubes should, ideally, be part of a
welded bracket and tube assembly to hold the
tubes accurately in place, avoiding the need
to weld the tubes in place, see Figure E74578.
•Care must be taken when tightening the spring
shackle bracket bolts and nuts to the correct
torque. See
Refer to: 1.15 (page 43).
(tightening torques).
•Extensions sleeved over the outside of the
chassis frame will necessitate the removal of
the under-run bar attachment flanges turned
out at the chassis frame ends. The cut edges
must be protected against corrosion.
Refer to: 5.10 Corrosion Prevention (page 221).
•Drilling of the top flanges turned out is only
permissible rearward of the spring hanger
brackets, for continuity of the altered extension
closing plate, if required. The diameter of the
holes should be 6.0mm maximum.
•If the chassis frame includes the inverted top
hat closure of the 4.25 tonne chassis double
cab variant, a similar closure must be included
in the extension and sleeved over the chassis
frame. It will be necessary to add two (2) holes
and reinforcing tubes in the inverted top hat
chassis frame vertically in line with the group
of four (4) holes see Figure E74578.

•It is recommended that the altered extension
has a similar closed section, material thickness
and properties to the existing chassis frame.
•An equivalent open section for the extension
assembly is at the vehicle converters
discretion.
•Lightening holes in new extension and cross
members are discretional.
•Do not weld original chassis frame except as
specified when adding reinforcing tubes,
please refer to Figure E745171.
•Do not drill the top or bottom surface of the
chassis frame, including the flanges turned
out, except as recommended above for
continuity of closure.
•Any alternative finish such as hot dip
galvanizing is at the discretion of the Body
Builder providing it does not have a detrimental
effect on the original Ford product.
Refer to: 5.10 Corrosion Prevention (page 221).
5.11.5 Frame Drilling and Tube
Reinforcing
The chassis frame may be drilled and reinforcing
spacer tubes may be welded in place, providing
the following is applied:
•Adhere to all details shown in Figure E74517.
•Drill and weld only side walls of the chassis
frame.
•Locate and drill holes accurately, using a drill
guide to ensure holes are square to frame
vertical centre line (note: allow for side member
draft angle).
•Drill undersize and ream out to size.
•Endeavor to remove all swarf from inside side
member, and treat to prevent corrosion.
•Fully weld each end of the tube and grind flat
and square, in groups if applicable. Be aware
of side member draft angle.
•Apply corrosion protection inside and outside
of the chassis frame.
Refer to: 5.10 Corrosion Prevention (page 221).
•Holes should be in groups of two (2), either
vertically spaced at 30 to 35mm from chassis
frame top and/or bottom surface, or
horizontally at 50mm minimum pitch, 30 to
35mm from top and/or bottom chassis frame
surface, please refer to Figure E74517.
•Always use M10 bolts with grade 8.8 minimum.
•Do not position tubes at the medium chassis
frame height, this may create “oil canning” of
the deep section side walls.
•Where possible, the outrigger moments should
be resolved by matching inner cross members
between the chassis side members inline with
the outriggers, please refer to Figure E74577-
Low Floor.
•A diameter of 16.5mm is the maximum
allowable hole size in the chassis frame side
wall, irrespective of the usage.
Avoid drilling into closed frame body members
to avoid the risk of corrosion from swarf.
Refer to: 5.10 Corrosion Prevention (page 221).
Drilling and welding of frames and body structure
have to be conducted following the program
guidelines. Please consult the Vehicle Converter
Advisory Service [email protected] for details.
5.11.6 Ancillary Equipment - Sub
Frame Mounting
Typical sub-frames and longitudinal members for
flatbed and low or drop-side bodies or equipment
exceeding the standard or Regular Production
Order frame length should adhere to the following
guidelines:
•Flat-beds and low bodies mounted on integral
longitudinal members (channel or box section
metal – not wood) must use both sides of all
frame mounting brackets, see Figure E74575.
•Longitudinal members must be relieved at the
front end if they are to contact the chassis
frame top surface, to minimize stress
concentrations, see Figure E74575. However,
it is preferable to mount the longitudinal onto
the mounting brackets, with a clearance to the
chassis frame top surface.
•Each set of brackets must use two (2) x M10
bolts grade 8.8 minimum.
•The rear two (2) sets of chassis frame
mounting holes / locations should have a full
bolt torque with 100% grip. The attachment to
the remaining forward chassis frame holes /
locations must be precisely located and
retained, but allow some relative flexing
between the sub-frame and chassis frame.
For example, clamp control devices such as
conical washer stacks or machine springs with
self locking fasteners.
•Minimum floor heights will require wheel arch
boxes to clear the rear tires, see Vehicle Data
sheets for relevant tire jounce.
•Chassis frame, for example: clamp control
devices such as conical washer stacks or
machine springs with self locking fastenings.
•Minimum floor heights will require wheel arch
boxes to clear the rear tires.
Pedestal mounted low or drop side bodies – (not
illustrated)
For bodies or equipment not exceeding the
standard or Regular Production Order chassis
