CHAPTER 1 GENERAL INFORMATION AND OPERATING INSTRUCTIONS
2.3.12 Engine Diagnostic Code Retrieval And Explanations
Turn the ignition switch to the ON position but do not start the engine. At any
time, cycle to accelerator pedal to full throttle and back to the idle position,
three times within 5 seconds.
If no active fault codes are recorded, both Engine WARNING (yellow) and
Engine STOP (red) lights will come on and stay on.
If active fault codes are recorded, the fault code will ash in the following
sequence:
1. The WARNING (yellow) lamp will come on for 2 seconds and then go off
2. There will be a 2 second pause, then each digit of the 3 or 4-digit recorded
fault code will ash in the STOP (red) lamp. There will be a 2 second
pause between each digit and also at the end of the STOP (red) lamp
sequence. Count the number of ashes in each digit to determine the
number of the fault code
3. The WARNING (yellow) lamp will come on again for 2 seconds and then
go off
4. The 3 or 4-digit fault code will repeat on the STOP (red) lamp
The lights ash each fault code out two times before advancing to the next
fault code. If only one active fault code is recorded, the control system will
continuously display the same fault code. To advance to the next fault code,
you can also cycle the accelerator pedal instead of waiting.
The explanation and correction of the fault codes can be found in “Cummins
Diagnostic Codes,” Chapter 5.
