Transmission Electronic Control
Unit (ECU):

and controls engine and transmission
functions and operating conditions.
ABS/ATC Control Module:
ABS/ATC
controller monitors road speed of each
wheel, braking conditions and ABS

DIAGNOSTIC PLUG LOCATION
The ABS/ATC, engine and transmission systems
communicate electronically over SAE J1939.
J1587 is used to retrieve diagnostic codes from
a particular system. There are two diagnostic
plug locations. The plug located in the engine
compartment has both J1939 and J1587. The
diagnostic panel located left of the steering column
below the dash contains a Diagnostic plug, a Vorad
diagnostic plug and ABS test button.
The Diagnostic plug has both J1939 and
J1587. The Vorad diagnostic has J1587. The
ABS button can be used to manually retrieve
ABS diagnostic codes that are displayed through
the ABS dash icon.
Engine Diagnostics:
The engine diagnostics will notify the operator
of deviations from the programmed limits of the
engine through the “Check Engine” lamp in the
dashboard. Should a system component with the
engine develop a deviation, the “Check Engine”
lamp will illuminate and a diagnostic code will
be logged and stored in the system memory.
These codes are accessed by a service technician
using special equipment.
ALADDIN™ ENGINE DISPLAY
The Aladdin System
displays engine and
transmission statistics.
Five additional engine
and transmission
screens can be
accessed. These screens
can be set to a rolling
display, or use the
controller to pick an
individual screen.
NOTE:
The backup camera and engine/
transmission screens cannot
simultaneously display.
