Dealer is saying they got a p0600 code in trans control module I don't see anything like this in manual and i don't see why he couldn't specify which P0600 code he was seeing because in manual it looks like that code can get specific as to which part has lost communication.

The Tech after saying he's pulled this code says he ohmed the BUS circuit comm line found ok. he then states that he got the car running a few time but it died shortly after. then says he removed the PCM connectors and thats when he found the Corrosion and stopped diagnosing my vehicle.

so do rcm failures ever throw p0600 codes?
