Water Bogged Question

[HarryO]

Hi All

First timer doing Cape York in August so when mounting my LLAMS I mounted it as high as possible but even that’s not very high.

My question is - What is the lowest piece of electronics that will fry and immobilise the vehicle if water gets into it - if you are unlucky (or stupid) enough to get seriously swamped in a water crossing (Eg Nolans Brook)

Looks like the ECUs are sealed units but not sure what their IP rating would be.

cheers Harry.

The transfer case ecu is not sealed ex-factory.

Reply Deleted - I did not read Graeme comment properly and asked a dumb question ..

Where is it located?

Presumably like the gu I'm rewiring atm connectors outside the cab are ingress protected but those inside are not. Basically if water gets inside the gu up to the tranny tunnel the ecu is toast.

Hopefully the disco is better😞???

D4's TCCM is mounted in the driver's side spare battery box in a black plastic enclosure that is open at the bottom for the connectors.

[INter674]

Ok that's reasonably high then.

BTW the Gu ZD30 tcu is in the pass footwell..even lower than the ecu. It is a known failure point from water ingress ..a really stupid location with no protection at all😐. There are also many ingress points in the Nissan eg open bolt holes throughout the floor pan and firewall.

Gawd knows why they are so highly regarded🙄

I've told my son to fit a bilge pump😃

And that is the reason you do not hose out your engine bay to give your engine a good wash.

[HarryO]

Perhaps I should clarify - I doubt I would be going through anything deeper that mid door level at the absolute most.

So if bogged for long the water may eventually get up to top of centre consule (Ie footwells flooded)

Any deeper than that and I will not risk it having learned my lesson when I swamped my D3 to just below the bottom of the door window about 10 years ago [bigsad].

[Graeme]

Probably becomes a statutory write-off in that situation.

[HarryO]

It was in WA and not written off - insurance covered it because it was on a gazetted road.

Car was in fresh water - right side & nose down so the drivers footwell was flooded and the rear right passenger was about 100mm - luckily did not have to replace any electronics.

It was just a major cleanup, WD40 on all connectors, dry and lots of bicarb for weeks.

drove the car for about 6 years after the flood - still had a faint smell when it was humid / raining.

will not be doing that again!

We used to drive our 3.5 D1 3 door with 36" tyres in water over the bonnet..and very little water ever got in ...amazingly ...and it never failed us..thankfully. Won't be doing that in the D4.

A bilge pump might be a good idea tho if you're expecting deep crossings. A relatives GU has one and it saved his car on the Tele track.

Dear Harry, I am addressing you formally because I want you to take me seriously.

i have done Cape York twice , and I know it sounds like fun, but don’t bother with Nolan’s Brook or any other mud/water crossing.

just drive in ,have a look ,enjoy the drama ,and continue on your merry way.

if you want a clean but still memorable drive , do the Bloomfield Track.

Auto tranny ECU for D2 is under the passenger seat,many have been destroyed by water.

Not a real smart place for it.

I got the D2a badly bogged in a small creek just off the Jardine,the carpets in the vehicle were soaked,and we had a heap of small fish in the vehicle,but luckily due to the angle of the vehicle the water did not get into the auto ECU.

Tirfor came in handy that day[bighmmm]

Thanks Dave - Noted.

Having flooded a D3 before I vowed never to repeat that again - I will not be doing anything silly again.

Anything deeper than about wheel height (with LLAMS fully extended) and I will most probably opt for the chicken tracks.

Cheers.

Mid-door level will be above the EAS (Electronic Air Suspension) module, which is mounted in the driver's footwell under the panel just in front of the door, if any water got in the cab, of course. Not sure where water would get in first, the doors have double seals, perhaps the spare wheel winch winder grommet cover would pop off?

It was always recommended that the large connector behind rear passenger side wheel was better sealed if deep water crossing.

There are chicken tracks around all those crossings I see on YouTube?

One my first trip August 1981, every creek and river except the Jardine ,had to be waded, no trouble for us in a 2wd F150.

six years ago in D3, and 3t van,we only went to the old telegraph track for a look. I would not take a half decent vehicle into Nolan’s Brook but is a bit like visiting a boat ramp at Easter, quite amazing the things some people do!

the development road we took in the D3 , well any sedan could do it easy.

tis a nice area of the continent , we spent several weeks there, as opposed to working folk who only have 3 weeks holiday to drive from say Sydney , and rush up and back
