Detroit S60 SID005 code

I have a 2005 Detroit S60 14L engine and the dashboard shows up the SID005 fail 05. The Check Engine and Engine protect icons are lighting also.

I have turned off the engine, checked everything including coolant sensor on overflow tank; I've checked for leaks and everything looks ok. After 10 minutes I've fired up the engine and everything looks normal (no dashboard lights on).

Do any of you have an idea of what this could be?

Thank you in advance!
