E3. Stop Engine
This red engine monitor warning
light will illuminate if a serious
engine malfunction is detected
in the electronic engine control
system.
• Electric propulsion to the
wheelmotors will be discontinued.
• Dynamic retarding will still be available if needed
to slow or stop the truck.
Stop the truck as quickly as possible in a safe
area and shift to PARK. TURN THE ENGINE OFF
IMMEDIATELY. Additional engine damage is
likely to occur if operation is continued.
Listed below are a few conditions that could cause
the stop engine light to illuminate:
• Low Oil Pressure - red warning light will
illuminate, but the engine does not stop.
• Low Coolant Level - red warning light will
illuminate, but the engine does not stop.
• Low Coolant Pressure - red warning light will
illuminate, but the engine does not stop.
• High Coolant Temperature - red warning light will
illuminate, but the engine does not stop.
A4. Cranking Motor Failure
This amber indicator will illumi-
nate when either starter motor
(of two) fails to crank the engine,
leaving just one cranking motor
to start the engine. With only one
cranking motor doing the work of
two, the motor life will be shortened. If this indicator
illuminates, truck operation may continue, but main-
tenance personnel should be alerted as soon as pos-
sible.
