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.

terminal must be no more than 2.0 mm.
NOTE: Ensure the existing nut is reused.
B+ Connection for Auxiliary Battery Charging
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.
