Model 944E

Origin 3/04

With the transmission disconnect activated, when the service brake pedal is applied,
the transmission will be disconnected allowing the engine speed to be increased
without the need to place the transmission shifter in the (N) NEUTRAL DETENT.

This feature eliminates the need to shift the transmission to the (N) NEUTRAL
DETENT before operating the hydraulic system at high engine speed. When the
transmission disconnect is active, the drivetrain is disconnected and the hydraulic
system has full engine power.

IMPORTANT! With the disconnect feature active and the service brake pedal being
released, the transmission will be reconnected in the same gear and direction of
travel as when it was originally disconnected. The service brakes must remain fully
applied for this feature to be functional.

Engine Function Indicator Lights

The engine function indicator lights (4) are located on the left side of the front dash
between the Park Brake switch and the Transmission Disconnect switch. The light
indicates any faults that arise in the engine during operation. The light contains a
RED light (5) and a AMBER light (6).

If the RED light (5) comes ON during operation, STOP the engine IMMEDIATELY
and diagnose the fault by activating the ECM diagnostic system. Activate the system
with the accelerator pedal.

Activate the system and read the code as indicated by the light. Contact your local
Cummins dealer for an explanation of these codes or refer to the Cummins Engine
Owners Manual or call the Cummins Customer Assistance Center at 1-800-343-
7357.

If the AMBER light (6) comes ON during operation, the engine diagnostic system
has detected a fault within the engine. Stop the engine and diagnose the fault by
activating the ECM diagnostic system.

Activate the system and read the code as indicated by the light. Contact your local
Cummins dealer for an explanation of these codes or refer to the Cummins Engine
Owners Manual or call the Cummins Customer Assistance Center at 1-800-343-
7357.

Cummins ECM Diagnostic System Activation

With the engine OFF, turn the ignition switch to the RUN position. DO NOT start the
engine.

Completely depress and release the accelerator pedal 3 times. This will activate the
system, both the AMBER light (6) and RED light (5) will come ON momentarily and
then will begin to flash the code. If the system has been activated with the
accelerator pedal and no faults are present, both the AMBER light and the RED light
will come ON and stay ON.

ECM Light Code Identification

The AMBER light (6) will flash one time to identify the start of the code followed by a
one or two second pause. Then the RED light (5) will flash the code sequence,
pausing for one or two seconds between numbers. The AMBER light will flash once
after the RED light has flashed the code to signify the end of that fault code.
