If the battery type on a vehicle is changed to other
compatible derivatives it is required to reconfigure
the vehicle to the new battery types at an
Authorized Ford Dealer. Central car configuration
can be updated at an Authorized Ford Dealer.
Battery Monitor System (BMS)
E223579
Ford Ranger vehicles are equipped with a feature
called Battery Monitor System (BMS). This system
measures the battery load in order to efficiently
charge the battery while improving fuel economy
and emissions.
It is important to ensure any additional electrical
load or accessory is properly grounded to the
vehicle’s body, in order for the system to identify
the additional load. If a connection is made to the
battery negative terminal, the BMS will not identify
the load or charge. This may cause the battery to
be undercharged and consequently not able to
re-start the vehicle.
Auxiliary Battery fitted to vehicles with
a Battery Monitor System (BMS)
NOTE: The addition of an auxiliary battery in a
vehicle with BMS would cause both batteries to
not reach a state of full charge. The system will
only allow charging of the batteries during
deceleration. Refer to Dual Batteries with BMS in
this section.
NOTE: Disabling the BMS will negate the fuel
economy benefit provided by the BMS.
NOTE: Auxiliary loads must always be connected
to the vehicle ground and not to the battery
negative terminal.
NOTE: Ensure the auxiliary battery connection is
safely secured using suitable fixtures to reduce
vibration damage or contact with surrounding
components.
For vehicles equipped with BMS, an additional
battery can be connected using one of the
following methods:
1. Use an in-vehicle battery charger (DC/DC
converter) such as BCDC1220 model from
Redarc (www.redarc.com.au) (or similar),
connected via an additional terminal to the
starter post terminal on the B+ using a 30A
fused connection and grounded to the vehicle
body, in the shown locations.
NOTE: The additional terminal must be installed
on top of the starter post terminal using the
existing nut.
NOTE: The maximum thickness of the additional
terminal being installed on top of the starter post
terminal must be no more than 2.0 mm.
NOTE: Ensure the existing nut is reused.
B+ Connection for Auxiliary Battery Charging
E251317
The B+ connection should be fixed to the terminal
posts using the existing nut with a torque of 13.5
Nm ± 2.1 Nm.
NOTE: Ensure the fused connection is secured
using suitable fixtures to reduce vibration damage
or contact with surrounding components.
