2006 FORD TRANSIT ECU

harness that provides roof-mounted rear turn
indicators, powered via relays. This should be
used in conjunction with SVO fusebox.
3.Chassis cab LED rear lamp cluster
replacement recommendations, especially
turn indicator relay implications – see lighting
load table. Generally the use of LED equivalent
lighting systems reduces the electrical load on
the vehicle; however, special care needs to
be taken with respect to any change to or
addition of turn indicator lights. Depending on
the current requirements of the LED(s)
compared to the bulb it is replacing, a ballast
resistor may be required, if not already
integrated into the LED lamp assembly.
Without this, bulb outage detection for turn
indicators will be affected, which is a legal
requirement.
Additional turn indicators must be powered
through relays (max 300mA), driven by existing
turn lights. The maximum load that the Central
Junction Box can drive is 3 x 21W per side (front,
rear and CAT 6 turn indicators); but even if the
vehicle is not fitted with the CAT 6 lights, the feeds
for these should not be used as the Central
Junction Box would need reconfiguring, which
could have safety as well as functional
implications.
4.Special Vehicle Option beacon switch: wiring
locations, circuit diagrams and max amperage
– see Special Vehicle Option fuse box
schematic (max current is 15A); there is
provision for the Special Vehicle Option beacon
switch in an empty switch location on the
instrument panel.
5.Rear loom connector detail location and supply
details for retro-fit loom extension for
example:- when extending a medium wheel
base, long wheel base or extended frame
overhang, what connectors do they use to
make a plug and play loom extension? – for
chassis cab vehicles, there is an Special
Vehicle Option extension loom for rear lamps
(part number 6C1V-14408-A*). There is not, at
present, a similar loom for Van, Bus and
Kombi's, although the appropriate mating
connector is now tooled, so this would be
possible.
Miscellaneous Systems
Handbrake on - Cluster Warning Light -
Unless the vehicle is specified with options that
drive the handbrake warning light (for example
ESP, Australia market), the components making
up this system are not fitted. We do not
recommend installation of this feature as an
aftermarket addition. There are several reasons
for this:
1.Not all circuits carry the requisite wire as a give
away:
•The wires might be part of the main vehicle
harness (14401) even if not used – for example
camper vehicles are normally ordered with
power mirrors, and the wires will be present
as a give-away.
•The seat pedestal harness (14K076), however,
is vehicle specific – if the handbrake is not part
of the specification, it will not be present or
give-away. This harness would need to be
changed to the compatible part that also
includes the handbrake warning light circuit.
2.The handbrake switch (part number
2F2T-15852-A*) together with its short jumper
harness (6C1T-15K857-A*) would need to be
obtained and fitted.
3.The handbrake warning light is in all clusters,
but unless the vehicle config. parameter
“parking brake switch” is set, the Central
Junction Box will not read this input, and hence
NO CAN message sent to the cluster.
Reconfiguration can only be done at a Ford
Dealer.
NOTE: If a vehicle already has a handbrake
warning light in the cluster, or one is installed as
per the Ford design, it is not possible to utilize the
wire from the handbrake switch as part of an
interlock circuit (this is a pull up resistor input that
provides a wetting current of 20mA – anything in
excess of this, for example through additional
circuitry, will almost certainly damage the Central
Junction Box). If there is no handbrake switch
installed, it would be possible to add one and
utilize this as part of a separate circuit, up to a
maximum current of 500mA through the switch.
Reverse Sensors (Rear Park Aid
Module)- The factory-fit option is a CAN-based
system, but for Van, Bus, and Kombi vehicles
only. Stand-alone systems can be installed (for
example for chassis cab conversions), but would
need to utilize the PTA line of the radio if muting
is required.
Fuel Fired Heater (FFH)- Add FFH: wiring is
only present (give-away) in certain harnesses.
There was an aftermarket kit available for this
system on current Transit, which could probably
be “updated” to suit V347/8.
Fuel Fired Heater (FFH) - Programmable
FFH: this utilizes a timer/control module mounted
to the Instrument Panel, which necessitates
having the correct Instrument Panel harness
fitted. Retrofit of this would be a difficult.
For both systems, the appropriate 6C1T-14K132
harness would be required (suffix -A* for
Programmable FFH, and suffix –B* for Add FFH).
Central Locking
Locking is controlled by the Central Junction Box
module. There is current sensing on certain
locking circuit pins as part of the security system
– if these are tampered with, locking cannot be
guaranteed.

However, it is possible to add an additional lock(s)
– see also the section covering the ‘third button
on key fob’ – but only by utilizing relays (the
electric locks are operated by surface mounted
relays in the Central Junction Box – these are
only capable of powering one lock each, in
addition to which the output of these devices is
current-sensed to check it is within minimum and
maximum limits: I) to verify operation, and ii) as
part of the security system). For camper vehicles,
the Central Junction Box is configured for a
chassis cab vehicle.
Depending on functionality required, the pins
used will emulate the basic locking/unlocking
operation of an existing door. Note, however,
that any additional locks will not be covered by
the vehicle alarm or operate Central Junction
Box controlled lighting, etc. It would be necessary
to splice into either the Central Junction Box
connector or the in-line connector for the door
jumper harness. The coil of the relay (max.
300mA) should be added across the relevant
pin and ground (i.e. one relay for lock all, one
relay for driver door unlock etc.)
The use of Ford Transit lock mechanisms is
strongly recommended as the Central Junction
Box is designed to drive these latches for the
correct amount of time.

Locking Configurations- The following list
details specific locking scenarios that have been
noted by customers:
1.Raid locking or drive away locking for taxi and
parcel van usage – this is a configurable
parameter in the Central Junction Box (Ford
Dealerships can set this).
2.Slam locking – this is a configurable parameter
in Central Junction Box (marketing want to
sell this as an option, therefore dealerships
can only switch off this feature, but not switch
on).
3.N1 lock reconfiguration into M2 locking, i.e. no
deadlocks – this can be reconfigured to be
central-locking only by a Ford Dealer (via
Dealership hotline).

Resistance Ladder

Resistance Ladder Circuit
DescriptionItem
To Green / White Wire1
Stop Engine2
RPM 1 on / off or Variable Control 'Idle'3
RPM 2 on / off or Variable Control 'Negative (-)'4
RPM 3 on / off or Variable Control 'Positive (+)'5
RPM control Armed or Increased Idle on / off6
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.

Static & Dynamic Sealing and
Finishing
Use Ford approved sealing and finishing material,
and underbody corrosion protection.
Refer to: 5.10 Corrosion Prevention (page 221).
Ensure proper sealing against ingress of water,
salt, dust etc. after cutting or drilling the body.
5.1.10 Tipper Bodies
For tipper conversions single an double Chassis
Cab versions except extended rear chassis
frame can be used. All variants allow single and
three way tipping.
It is recommended to have the tipping system
operative only when the engine is running. It is
also recommended to have the master control
switch in the security of the cab. According
routing of wires and hydraulic lines please refer
to section hydraulic lift.
Ensure that axle plated weights including the
front axle minimum are not exceeded.
For tipper sub-frames please refer to the
following guidelines:
•Design for full length continuous frame with
mountings for motor, pump unit, reservoir,
pivot points and ram
•Use all mounting points on chassis frame to
mount sub-frame
•The rear two sets of chassis frame mounting
brackets should have a full torque with 100%
grip. The attachment to the remaining forward
chassis frame brackets must be precisely
located and retained, but allow some relative
flexing between the sub-frame and chassis
frame. That is clamp control devices such as
conical washer stacks or machine springs with
self locking fastenings.
•Very stiff sub-frames may damage the chassis
frame by preventing its natural flexing,
therefore compliant mounts should be captive
fail safe with up to plus and minus 12mm
compliance, vehicle laden or un-laden
whichever is worst case, rated 2mm
deflection minimum per 200kg mass at each
chassis frame forward mount, please see also
Figures E74696 Sub-frame attachment to
Chassis frame and Figure E75880 Rigid or
Torsion Stiff sub-frame for Chassis Cab.
•Use two M10 grade 8.8 minimum bolts,
washers and self locking nuts at each solid
and compliant chassis frame location.
•Sub-frame must extend to the back of the
cab and attach to all mounting locations, with
the forward end designed to minimize local
frame stress, please refer to Figure E74575
Sub-frame for low floor or other equipment.
However it is preferable to mount the
sub-frame onto the mounting brackets with
a clearance to the chassis frame top surface.
•Side tipping loads/forces must be resolved
by the sub-frame. It is not recommended to
strain the chassis frame.
5.1.11 Tank and Dry Bulk Carriers
Due to the high rigidity of tanks it is necessary to
isolate the tank and its sub-frame from the
chassis frame allowing the chassis frame to
naturally flex. Please refer to the following
guidelines:
•Mount tank to full length of sub-frame.
•Mount sub-frame to all chassis frame
mounting points.
•The rear two sets of chassis frame mounting
brackets should have solid full bolts torque
with 100% grip.
•The remaining forward location mounts must
be compliant to allow relative chassis frame
to sub-frame deflections.
•Sub-frame must extend to the back of the
cab and not contact chassis frame at forward
end under worst case deflection.
•Compliant mounts should have captive fail
safe through bolts, please refer to Figures
E74696 Sub-frame attachment to Chassis
frame and Figure E75880 Rigid or Torsion Stiff
sub-frame for Chassis Cab, with up to
plus/minus 12mm compliance, vehicle laden
or un-laden whatever is worst case, rated at
2.0mm minimum deflection per 200kg mass
each.
•Use two M10 grade 8.8 minimum bolts,
washers and self lock nuts per chassis frame
mount bracket at each solid and compliant
location.

Authoring Template
5.3.1 Load Compartment Interior
Lining
Do not damage the lock or latch system
(electrical cables, release system) when applying
interior lining.
WARNING: Plan fixing points for
other fitments such as racking to
ensure through bolting can be
achieved. Fixing to the lining
material may be inadequate for
normal safe operation of the vehicle.
The additional weight of the linings on doors may
require additional reinforcements to the door and
pillar at the hinge and check mechanism.
5.3.2 Security, Anti Theft and
Locking System Security
NOTE: It is not recommended to alter the
locking system.
However, in case a modification is required for
the conversions, please consult the Vehicle
Converter Advisory Service [email protected].
To avoid locking system security complications,
it is recommended to discuss with the local Ford
dealer prior to modifications taking place.
The Central Junction Box is designed to work
specifically with the Ford Transit lock and latch
mechanisms and therefore drives latches to lock
and unlock for specific time periods. Additional
power locking functionality should be based
around the use of additional Ford Transit latch
mechanisms. Additional latches can be driven
via relays connected in parallel with existing
latches.
On Chassis Cabs fitted with a high-level
Passenger Junction Box, the cargo door latch
driver is not used by the base vehicle and can
be used by Body Builders wishing to add power
locking capability to the vehicle load space. This
latch can be controlled via the driver's door key
barrel or the cargo unlock button on the remote
key fob (dependent on vehicle configuration).
The following figures outline the areas in which
it is not advisable to drill:

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.
