2007 NXS, 530k
Twice in last couple of weeks, it has thrown code # 55 (checking using cruise control). Don't know if it means anything, but both times this happened when taking off after ten hour break, during which engine ran @ fast idle, (which is usual). Can't say I noticed the first time, but second time the yellow cel was flashing, it de-rated engine for a short while- when it stopped flashing, engine returned to normal.
I had printed out a set of code #s some one had posted long time back, but can't put my hands on them; also seem to think they were for single turbo Cats. Is same code #s also good for Accerts?
Would appreciate if:
Someone could direct me to the post showing the code #s, and/or tell me what #55 is.
Thanks in advance!

55 means everything is good at the time you check it.
droy Thanks this. -
Or does it think you want to check for codes and slows ECM functions while checking?droy Thanks this. -
Just looked in my book to be sure. 55 is no codes found. Not to say u don't have a problem. Its just not throwing a code.
droy Thanks this. -
Next time it does it and the light is blinking you need to take a snapshot to get the ecm to log it. If I remember correctly you just hold the resume switch down for about 5 seconds and it will log it.

check the sensor for low water. it will derate it but not throw a code. if it derates again with no code just unplug the the harness from low water sensor and it will run just fine until you get a new one.
