Mechanic's Assistant: Anything else you want the truck mechanic to know before I connect you?

I already took off the def valve located at the pump that is connected to an air line and removed the spring in there it was all clean i thought the code that it was giving me ecc 61 fault code and 01 would be of low pressure but no oil came out when i removed the spring what i didnt remove was the valve itself on you tube the person that was recording the video said if no oil came out the valve was still in good condition
