I'm confused, this is the wire to the motor?

Then it is 3 phase AC... made up by the inverter system from the DC from the battery

(DC does not typically need shielding or make radio noise, AC does)

 

I stand corrected. You’re right.

 

3 1/2 years ago I published a post on the now famous "CableGate: issue: CableGate Post # 507 In that post I stated that I used CRC Heavy Duty Corrosion Inhibitor and Permatex Dielectric Grease. This is what the connector looks like today:

Note the 2 holes in the bottom of the orange connector cover. The next picture is the connector with the orange cover removed:

Other than the dirt, the metal braid around the 3 wires looks just like it did 3 1/2 years ago.

Please Note, the discoloration of the braid and the metal clamp around the connector is not corrosion, it is CRC Corrosion Inhibitor.

After a light spray of mineral spirits to remove the dirt that had accumulated the past 3 1/2 years (and letting it dry, I sprayed the braid with another 3 light coats of CRC Corrosion Inhibitor. The connector was attached to the motor (again using a little Permatex silicone grease.

Note that the orange plastic cover does not fit tight around the metal connector. This allows dirt and water to enter the connector - which is probably the root of the corrosion problem.

Looks good and is holding up ok
As an rf guy I am not happy with the gaps in the shield braiding…
Poor design in the cable for this use..

Yea water and minerals are the makings for a bad day when you add in some electricity in the mix.

They need to take lessons from the old classic pots telephone BIG cabling
They use nitrogen to push water out of the jacket and use corrosion control the techs slang as icky pick.
Nasty ultra sticky stuff that it takes gasoline soaking to melt it..
It gets everywhere when dealing with phone cableing trunks like a 1700 or 3600 pair trunk for splicing…
The new fiber stopped having to deal with that.

Maybe in the future they might go a fiber optic for the lan in automotive
Then only have to deal with fat power wires for connections
And seal up the control modules 100% if used outside the passenger cabin.

Potted black box stuff…

God only knows what that will do to the price to an over priced modern automobile ….

Everything breaks or goes bad over time
It is all about lasting as long as the rest of the automobile…
And doing it on the cheap…

 

I guess I thought that corrosion on that braid worked it's way up to the connector.

This is DC voltage, it’s not 3 phase power. The braided wire you see is shielding. When that corrodes, you start to have issues with AM radio and possibly other symptoms.

Not DC, It is three phase AC. The corroded shielding may contribute to AM static but noise is caused by three phase leakage which will eventually trip inverter ground fault or phase imbalance protection and stop car if leakage is severe enough.

 

So every time I've seen corroded cables it's looked like rusted steel. Why am I seeing what looks like copper corrosion there?

 

Must be some copper in there.

 

At some point is there an expectation that there will be some work instructions (maybe not the right term) for the repair? As has been mentioned, if there is corrosion that should get fixed before wrapping everything up right????

 

Yup
Got to stop the reaction before sealing in the damage or it will trap the reaction and make it worse

 

Just called my dealer (where I bought it, not the place on the other thread!). They will inspect the cable while I wait on Friday. They will then either schedule to do the wrap or order a new cable based on their findings. So, at least at this one, they know to check before covering!

 

I have to think that anyone who has driven the RAV4 in actual winter conditions for a season or more would have the start of some corrosion but maybe not.

 

Thank you for pointing out the service campaign. I just made an appointment at my dealer for Friday morning. This is a good example of how this forum serves its members.

 

I just received this notice on the Toyota App today on my 2019 J Vin.

 

Is anyone seeing unlimited mileage coverage for this cable issue or just 100k miles 8 yrs. That's what my dealer told me

 

The new service campaign detail I post on the other thread make it clear that it is unlimited miles if you get the job done:

Everyone, we have three parallel discussions going on on three threads, all about the same topic. Many of the comments on each thread are just repeats of information on the other threads. Wish I had merged the three threads ages ago.

Rather than merge them, which would make a real mess, I'm going to close two of them and ask that all conversations continue on the remaining one: https://www.rav4world.com/threads/service-campaign-alert.342531/unread
