Found in my Passport, probably purchased from the previous owner. With 20 plus years of wrenching, I have seen number of vehicles continue to rust away with a similar system installed. I discovered it 3 days into ownership of my beauty. I was under the dash scoping out the brake controller connector. I looked up to notice large number of fuses above the kick pedal and bracket with light corrosion.That day I removed, cleaned and lubed (dielectric grease) all fuses in that panel. My theory is that this product doesn't work and adds another draw to the battery, without actually preventing rust. The vehicle already pulses electrical charges throughout the chassis as it sleeps. Even my brake controller pulses power for 15 mins before it turns off. It allows current to flow through the wiring and cycle back to the battery. Living in the Ontario the road salt and weather rot away most vehicles. Dodge, Kia, GM, Mazda are the front runners. I use a product called Krown and have never had rust issues. No need for it... thinking I might say goodbye Diamond Kote.

I thought maybe I had been in a coma and missed something and just woke up!
What the . . . .!
From their website - 'It safely utilizes the vehicle’s power system to deliver electronically controlled low voltage to the entire metal structure of the vehicle.'
So they are saying it leaks current from the 12v in the OBDII plug to grd thru a variable resistor (maybe).
What a bunch of b.s.!
Sure is hard to find out how much they sucker people into paying for this load of crap.

I found this very interesting. Having lived my entire life no more than 50 miles from the San Diego/Mexico border I had never heard about rust control modules. I spent some time reading about them. Seems like they are a dealer "add-on" that is more than a warranty than a true rust control product. I also read that dealers charge up to $1000 for them. One can learn a lot on this Forum!

BTW- What brand and model of brake controller did you install on your PP?

I installed Tekonsha 90885 - Prodigy P2 Brake Controller. Haven’t utilized it due to Covid-19. No vacations or adventures with my Passport currently on the horizon.

Swindlers and con-artists also need to eat, at least until they get their stimulus check (where's mine?).

This is what some of the very early Pilots look like from the rust belt.
Some of those small pics you have to right-click/open image in a new tab.

I am sure glad I don't live in the rust belt anymore. I remember as a teenager driving the family '49 Plymouth when the body came loose from the frame on the rear mounts. Weird to see that bouncing around.

I can't believe in this day and age that they haven't figured out how to prevent this from happening. Unless of course they have, and it's too expensive to implement.

Update. I unplugged it this morning before work. Noticed a LED light on as the unit was plugged into the OBD 2 scan port. I never did measure the current draw from the unit. Oh well, it will just end up in the garbage, unless someone offers me nothing for it. I wonder what the stealership sold it for? Poor previous owner, I’m sure it wasn’t cheap. I’ve already undercoated my Passport for the first time. With the vehicle on a lift and all tin and plastic covers removed, it was easy to access all areas of the chassis. Krown or another type of oil based undercoating is what I’d recommend for those in the salt belt.

Got one , We think it is what is causing my car not to start sometimes. No one from the dealer or Diamond Kote will talk to me about it. jeep Canada wont cover any repairs if the wireless model is the problem , even though they sold it to me . The only way to buy one is through the deal at the point of sale. Diamond kote does not have a sales or tech department , only warranty claims for rust. It would seem the relationship between the dealers and Diamond kote is not covered as warranty buy the manufactures even though it is a point of sale agreement. I can see from other reviews that it is always on . my car may be reading it as a fault , the car will sometime go into a safety mode . or the push button start locks the brake . it is always on because I can see the power light when the car is off. The dealer has had the car 5 times now and it still does it. the car only has 8000 km on it , and no one from jeep or the dealer knows what causing it .

Thats terrible, I'd be removing it from your OBD II port ASAP. The silly fake rust module will causes a slight draw. Overtime with the vehicle parked for extended periods, this will draw down your battery. It also doesn't prevent rust.
