Retreiving Codes '07 387 Cummins ISX

Started getting a check engine light the other day.

Google told me to....

Use the following procedure to retrieve the flash codes if the engine is equipped with a diagnostic lamp:
1. Turn the ignition key to the ON position/Engine off.
2. Turn the cruise control ON/OFF switch to the OFF position.
3. Move the SET/RESUME switch to either position. Hold that position until the yellow lamp begins to flash.
The yellow lamp will flash in order to indicate a two digit flash code and the SET/RESUME switch may be released. The sequence of flashes represents the system diagnostic message. Count the first sequence of flashes in order to determine the first digit of the flash code. After a two second pause, the second sequence of flashes will identify the second digit of the flash code.

All Flash codes are 2 digits.

But I get no flashing lights
Any ideas?

 

I was afraid of that
