Stop engine immediately

I have a kenworth t680 every time I get a truck wash I get the STOP ENGIEN IMMEDIATELY CODE pop up I have read that ist becuse the ecm gets wet is thier any place in specific or something specific I can do to stop this code from poping up today june 13 the code stayed on for 2hrs after the wash so I did a reset and it's no longer there wondering now if I ####ed up? Also if any one knows how much is an ecm for a cummins isx someone told me there like 10k but I looked mine up and its only like $1600 was that guy just trying to me or why would he tell me that

 

Are you getting an engine wash when this happens? If so, stop it!

 

Do not let them point the hi pressure water near the ECM or wiring that leads out of ecm!!

 

The ECM is a computer and very sensitive to moisture. It’s ok to wash under the hood but be careful around it. It should be impenetrable to moisture but unfortunately it’s not. I have heard this before.

 

Yep
I was just gonna say, stop gettin a truck wash , save the $$ and keep rolling.

it usually doesn’t look much better after the wash anyway.
There’s a reason the blue beacon truck wash is called “the streakin’ Beacon “

 

No I don't get engien wash to often I'm guessing it's just water that lands around with all the hoses they use

 

They done its just water that's runs down I don't get engien Wash too often

 

Yes I try my best but I think it's just water that runs down that wets it just enough

 

I steam clean the engine of every vehicle I've ever owned, engines of trucks, heavy equipment etc and have never once had a code or issue arise because of it. You can spray water all over that engine and wiring with no worries. Its when you stick the wand tip 6 inches away from that stuff that you cause damage. Keep the tip 2 or 3 feet back it should never been an issue.

 

You need someone with computer to figure out what sensor cause STOP ENGINE and check sensor rubber cover.
