P606 is control module processor problem it is stored in the freeze frame section you can try to erase it but it may come back. I would put dielectric grease on the connection at PCM and tell the person to quit driving through water he is lucky it runs. if it will not clear then another ECM/PCM.

if it continues to come back then the ECM needs to be replaced of course you will need to reprogram the security system for truck to start.
