i've got 2 active and 2 inactive codes,cummins 2007,isx,500hp,what it means.

First the two active:M 128 PID131 FMI 4
M128 PID 411 FMI 0 ENGINE ECU

And the two inactivе:M 128 SID 231 FMI 9 engine ecu
M 144 PSID 230 FMI 4 Vehicle ecu
The truck seems to run fine,except when the engine is cold working strange
like RPM'S going up and down and the whole sleeper is moving a lot,but its been like that for almost 3 years,and now these codes.ANY IDEA?
I forgot ,when the engine got warmer the rpm got normal.

 

i can't find the first one,strange,and the second one-can't understand it,strange explanation.ANY HELP,PLEASE!

 

Thank you for the post,but i can't find a solution there.

 

i'll try that,thank you.
