6 month old transit and the PCM is all corroded already

While poking around in the engine bay of my 2019 van, I can see where rain water dumps directly on the PCM and its wiring harnesses and connectors behind the radiator overflow bottle on the driver's side. WTF?! The PCM's aluminum body is already corroded and covered w/ white Al oxide. I am in S FL and humidity and rain is the name of the game this time of year.

Has anyone come up w/ a mod (ala TURD) to protect the PCM and its connectors?

On my 2019 I have the air box fix... though I've not opened it to see if it is really fixed.

I wrapped mine with a small plastic bag and used zip ties. 2+ years and it's working fine.

If you can find a place where the transport fumes are not overwhelming, you can almost taste the salt in the air.

LOL. Indeed! Many have this. The black plastic I have covering the ECU should hold up pretty well and stays in place by friction. The plastic bag tie wrapped
around the electrical harness above it probably won't hold up as long, but it was easy protection and I'll just replace it when it deteriorates.

"PCM" does not come up in search results for this forum. What is it? Thanks.

It is the PCM, Powertrain Control Module.

Starting about Post 12:

https://www.fordtransitusaforum.com/...problem-2.html

Sometimes it is called the TCM...
https://www.fordtransitusaforum.com/...since-new.html


It comes up in forum searches sometimes as the ECM, Few people have the service manual so many just make a good guess at the proper name for a forum thread

Could you inform which sterlite dishpan that it? Any more pix? Thanks.


It is tough going back to cars designed (and I use that term generously) by the big 3 after toyotas and mazdas.

IIRC, it was the 8 quart Sterilite dishpan, but don't know for sure. Sorry , I don't have any more pics - you have to move the coolant reservoir out of the way
to get to the ECU.
