Output terminals for additional wiring
The signal detection and actuation module control unit
has circuit output terminals for additional wiring as
listed below. Connect power or signal cables to the
connectors used for body equipment to add the wiring
as required.
Unit: A
(a) Cautions when using output terminals for
additional wiring
• Allowable current values are specified for
the output terminals. Make sure that the
rated current for any additional electric part
to be used is lower than the specified
allowable current.
• When any diagnostic function of the output
terminals marked* is used, it is necessary to
change data for the signal detection and
actuation module. For details, ask the
department responsible. É 2.1
• When a signal output terminal is used to
operate any body equipment-side
apparatus, use it as the activating side for
operation relay. The relay used must be the
noise-absorbing element-incorporated type.
• The output voltage differs according to the
vehicle. Refer to "Power supply voltage"
É 8.1.1.
• For necessary output lead-out connectors,
see "8.4.3 Mounting location of optional
terminal" É 8.4.3.
• When trailer is connected with coupling
device, it is necessary to change data for the
signal detection and actuation module to
activate diagnosis function for the lamps.
For details, ask the department responsible.
É 2.1
(b) Precautions for body building and modifying
electrical parts
SAM control unit will detect an error if an
electrical part is added or replaced improperly.
A warning lamp then goes on and remains on or
the power is shut down, resulting in vehicle
failure.
• If an electrical part is to be added or a lamp
is to be replaced with an LED lamp, the
current value of the electrical part should be
ensured to fall within a specified range. This
is, however, does not guarantee that the
electrical part to be mounted will be fully
operational when its current value falls
within the specified range.
• For the specified current value, consult an
authorized MITSUBISHI FUSO dealer or the
department responsible É 2.1.
• Body building or modification of any of the
following electrical parts requires that the
SAM control unit parameters be changed.
Consult an authorized MITSUBISHI FUSO
dealer. Some parts to be mounted may not
be fully operational depending on their
specifications or the vehicle specifications.
Major body building and modification
examples:
• Mounting a centralized door lock and
keyless entry system
• Mounting a heated mirror
• Mounting fog lamps
• Mounting the step lamp
• Modifying the rear combination lamp
[incorporating LED]
• Adding a turn signal
• Modifying the license plate lamp
