Aww Hell what did I do? HELP!!!

[Lilfarmrboy]

Alright here is the run down. Saturday changed the oil, oil filter, new fuel filters, Sinister coolant filter, Racor filters on everything. Today I power washed the truck and gave her a much needed bath. While I was under the hood I noticed that either me, or someone else didn't screw the power brake fluid reservoir cap back on right and some brake fluid was dripped down on the area under the reservoir and some of it got on the driver side of the motor. Me and my genius thinking while washing the truck decided to power wash off the gunk making sure not to hit any of the wires, electrical boxes, or the FICM. Now my little wrench light is on It was not on at all after changing the filters and the truck still runs fine, no miss, no starting problems, and according to the code reader no codes to be found. So now I am at a loss as to what it could be? Any help or things to look for will be helpful. I really don't want to have to take it to the stealership if I don't have to. Also would it be safe to drive the truck for about 2 days if I have to take it there? (Won't be off until Wednesday...)

Let me add that I also flushed and changed the coolant and put back in G-05 (yell at me later). Did not have any wrench light until after the power wash. SMH.

Did you get any water in the master cylinder?

No, made sure not to get any water on anything that I know would cause trouble. Only kept the nozzle just under the plastic reservior to get to the metal tube that runs under it and on the driver side of the motor where some of it spilled down on to. As far as I know no water made it into any of the elecrical boxes and that area along the fender wall stayed dry. I'm stumped...

Me too lol I don't know much about 6.0s but on my 7.3 the ecm is directly under the master cylinder going thru the firewall. Might be in the same place on yours

I will have to check in the morning. I hoping that if anything at all maybe some water got into something that will dry and it will go away... but the only luck I have is bad luck so I'm sure that won't be the case. Funny thing is if it was something like the ECM the truck shouldn't be running, or at least that's what I think.

Ya I would think so too but you never know. Maybe it got a lil wet, freaked out and threw a code. Also...what year is your truck? And is the wrench a check engine light or a service light?

Wrench light only, not the engine light. It is an 05. No codes according to two code readers.

I would look in your manual and see what triggers the wrench light to come on
