– 30 –
14. ABS Warning Light
This warning light monitors the vehicle
anti-lock braking system (ABS). This
warning light will illuminate when:
• the ignition is switched on; the light
should extinguish as soon as the
vehicle road speed exceeds 5 mph
(7 km/h);
• the vehicle ABS is defective; the
conventional braking will remain
operative but the vehicle must be
driven with care and the ABS must
be rectified at the earliest opportu-
nity.

“Driving”
and
“Emergency
repairs”
sections of this handbook.
15. Maintenance - Water in Fuel
This warning light will illuminate if the
water/fuel separator needs to be
drained.
16. Check Engine Light
This warning light will illuminate when
an engine problem exists, but the vehi-
cle can still be safely driven. The vehi-
cle should be serviced to correct the
problem but the situation should not be
considered an emergency.
17. Stop Engine Light
This warning light will illuminate when a
major engine problem exists. It means
you should stop and shut down your
vehicle as soon as it is safely possible.
NOTE: If you need to determine
the exact engine problem that
turns on warning light 16 or 17,
you must access the on-board diagnos-
tic system. With the key switch ON but
the engine NOT running, press the
throttle pedal to full throttle and release
to idle three times. The active fault
codes will flash out as described in the
Cummins ISB Engine Operation and
Maintenance Manual. Contact your
dealer or the Cummins engine service
center for the explanation of the code.
Turn the key switch OFF to exit the
diagnostic mode.
18. Coolant Temperature Warning
Light
This warning light will illuminate and a
warning buzzer will sound whenever
the engine coolant temperature
exceeds the maximum permissible
level.
