B. Engine Function Indicator Lights
The engine function indicator lights (2) are located in the upper
switch bank on the right side of the front dash. The light indicates
any faults that arise in the engine during operation. The light
contains a RED light (3) and a AMBER light (4).
If the RED light (3) 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 RED
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 (4) 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 three times.
This will activate the system, both the AMBER light and RED light
will come ON momentarily and then both 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 will flash one time to identify the start of the code
followed by a one or two second pause. Then the RED light 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.
