Trailer Towing - Ford RANGER 2015 Body And Equipment Mounting Manual

4.3.6 Trailer Towing

Vehicles with a factory fitted tow bar also come
with a trailer tow module for lighting and the
activation of trailer sway control. In addition to
providing the trailer plug functionality, the trailer
towing module protects the primary electrical
circuits of the vehicle from any electrical concern
or failure that the customer's trailer may
experience.
NOTE: The trailer tow electrical kit is available
from your Ford authorised dealer.
For vehicles fitted without a tow bar as standard,
a genuine Ford accessory trailer tow electrical kit
has been developed to enable a tow bar to be
installed. The kit comprises of the trailer towing
control module, trailer plug, wiring and associated
hardware components.
Once the kit is installed, the vehicle must then be
configured using a Ford IDS diagnostic tool. This
configuration can be performed by your Ford
authorised dealer.
WARNING: Installation of aftermarket
trailer tow electrical kits or directly
splicing into the vehicle wiring in order
to install trailer lamps or other electrical
devices may overload the system and
impact the operation of other vehicle
systems.
Ford recommends that all trailer tow electrical
connections use the genuine Ford accessory
trailer tow kit.

When fitting low power LED (light emitting diode)
lamps that require less than 2W, the lamps may
flicker when in use. A trailer patch harness should
be used with low power draw LED lamps.
CAUTION: Do not connect the trailer
patch harness to the vehicle when the
trailer is not connected.
NOTE: The trailer patch harness is available from
your Ford authorised dealer.
NOTE: The trailer detect circuit is part of the Ford
Trailer Tow module, it can only be implemented
on vehicles with power locking and perimeter or
CAT 1 alarms.
The Trailer Tow Module (TTM) can support pure
LED trailer lamps as long as each circuit exceeds
500mA, below this and the system will not detect
a trailer has been connected and shuts down all
outputs (sleep mode). It is recommended to
target a 550mA minimum load to allow for
system tolerances. This would need to be
obtained with a supplemental load resistor, if the
LED lighting circuits are below this threshold.
Each output driver could handle a current of 15A
but it is not recommended to always run to this
maximum. A higher current is interpreted as short
circuit. If a short circuit is detected the related
output will be switched off. The following table
shows the recommended output maximums per
circuit.
NOTE: Not all features and outputs are supported
in all markets. Refer to your authorised Ford
Dealer for further information.
