B.A.E.™ Hybrid Propulsion System
Page 44
The HEV propulsion system does
not require a transmission resulting
in a smooth vehicle acceleration.
The gear selector drive modes are
Drive (D), Neutral (N), and Reverse
(R).
Prior to gear selection (Drive or
Reverse), the operator must first
select Neutral. Failure to do so will
cause the PCS to detect a failure in
the Hybrid Propulsion system
resulting in the STOP HEV light to
illuminate and preventing the
vehicle from moving.
Stop HEV Indicator
This red indicator illuminates when
a severe fault is detected within the
hybrid propulsion system. When this
condition occurs, the vehicle should
be removed from service
immediately.
Some possible causes:
1. Neither Drive, Neutral nor
Reverse gear has been
selected.
2. Both Drive and Reverse gears
have been selected.
3. The front instrument panel gear
selector switch has failed.
4. The wiring connecting the gear
selector switch to the PCS has
failed or shorted.
5. The PCS has failed.
6. Throttle pedal output voltage is
lower than the minimum
allowed value when the pedal is
not depressed.
7. Throttle pedal output voltage is
higher than the maximum
allowable value when pedal is
fully depressed.
8. Throttle pedal output voltage
and the Throttle Pedal Idle
validation switch position do not
correlate.
9. When the ACTM begins to
overheat.
