Instrument Cluster

DESCRIPTION AND OPERATION (Continued)

The charge indicator illuminates when the key is
turned to the RUN or START position while the
vehicle is connected to the power control station
(PCS). If the lamp flashes when the key is in the
RUN position, the BCM has detected a vehicle
malfunction and the traction battery cannot be
charged.

The malfunction indicator lamp (MIL) will
illuminate when a diagnostic trouble code (DTC)
has been set in either the IAA module, BCM, or the
TIM. The IAA module has two special DTCs to
indicate that the BCM or TIM requested the MIL to
illuminate.

The low oil pressure indicator is illuminated by the
IAA module when the TIM senses that there is a
low oil pressure condition in the motor/transaxle.

The brake warning indicator will illuminate if the
TIM detects a problem with the regenerative
braking system, if there is low fluid level in the
master cylinder, or if the parking brake is engaged.

DESCRIPTION AND OPERATION (Continued)

The electrical hazard warning indicator (LED) will
illuminate if the BCM detects current leakage, or if
one of the high-voltage interlocks in the traction bus
or the auxiliary high-voltage bus is open. The
electrical hazard warning indicator will also flash
and the malfunction indicator lamp (MIL) will
illuminate if the BCM detects an improperly closed
or welded negative contactor. The LED is the same
one used for the theft indicator in the standard 2001
Ranger.

The power limit warning indicator is illuminated by
the IAA module based upon data received from the
TIM through the SCP network. The indicator
indicates that the vehicle’s performance has been
limited due to a low SOC or a vehicle malfunction.
The indicator will begin to flash when the vehicle’s
performance is severely limited due to an extremely
low SOC or a vehicle malfunction. This indicates
that the vehicle’s performance has been further
limited to allow for safe parking of the vehicle
before the vehicle becomes unmovable under its

The low state of charge (SOC) indicator indicates
that the traction battery has a 10% remaining SOC.
Once the vehicle’s traction battery reaches 0% SOC,
the indicator will flash. The indicator will also
illuminate or flash if a fault occurs in the system.

The instrument cluster removal and installation for
the Electric Ranger is the same as the standard
gasoline Ranger. The bulb replacement also follows
the same procedures; there are however, unique
indicators. The preceding figure illustrates the name
and location of the indicator lamps. Use the
standard workshop manual to remove and replace
the cluster, and use the preceding figure to identify
and replace the bulbs.

Inspection and Verification

•

DTC B1834 Gauge Drive Current Fault

Refer to

Section 100-07

.

— The interface adapter assembly (IAA) module

monitors the gauge drive circuits for the
traction battery state of charge (SOC) gauge,
the temperature gauge, and the economy
gauge. The IAA module sets DTC B1834 if it
detects an overcurrent condition in any of
gauge drive circuits for the gauges identified
earlier.
