Dpf And Rpm Speed Control - Ford TRANSIT 2016.75 Mounting Manual

Using this method it is easy to change between
these two modes of operation for the RPM speed
controller.
How to change the 3 pre-set default RPM
values in the 3 speed mode
NOTE: If the engine RPM responds to the initial
RPM button press, then the vehicle has not
entered 'learn mode' correctly and 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' and you will have to restart the procedure.
1. Enter 'learn mode' (see directions above).
2. Arm the RPM speed controller (turn the key
switch to 'on').
3. Press and release the brake pedal once.
4. Press and release the RPM button that requires
re-programming.
5. Use the accelerator pedal to rev the engine to
the new desired RPM speed and hold at this
speed (only speeds between 1200 to 3000
rpm can be selected in 3 speed mode).
6. Press and 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 and 'learn mode' exited (see below).
How to save new settings and exit from
'Learn mode'
NOTE: The engine stalling indicates that the
settings should have been saved and the vehicle
has exited from 'learn mode'. Learn mode however
is very specific that the exact steps are taken in
the correct order and within certain time limits
otherwise the learn procedure fails and it may
take several attempts to get this order and timing
correct and a successful modification from the
default settings.
1. From within the 'learn mode' and with the RPM
Speed Control switch box 'armed', fully press
& release the clutch pedal at least five times
in quick succession. The engine may stall out
on the last depress which is normal, however
if the engine does not stall out after at least 5
clutch pedal depresses, then you can key off
after the sequence of rapid clutch depresses.
2. Restart the engine and test the new settings,
repeat above procedures if necessary.

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 and 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 lamp illuminates then RPM
speed control will stop in order to protect the
engine.
• If the low fuel level lamp 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
while 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.
• 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 anti braking system (ABS)
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.

4.8.3 DPF and RPM Speed Control

The Diesel Particulate Filter (DPF) captures soot
in the exhaust fumes to improve vehicle exhaust
emissions. The condition of the DPF is monitored
by the vehicles electronic systems. Under normal
driving conditions a regeneration feature is
triggered to clean the filter. If the DPF becomes
full, a red engine warning lamp illuminates on the
instrument cluster and the vehicle will need to be
taken into the local Ford dealer to have the DPF
specially purged.
