Disconnecting either the positive or negative battery lead to isolate power for 3 seconds is more than enough time to drain any residual power from supply-line capacitors in ecus. That is, all power will have been drained before one has time to detach the 2nd battery cable!Quote:

The connectors that need sealing.D3 battery area,Transfer case module is behind the battery,remove battery spray the contacts(D4 is moved to the drivers side battery area).EAS compressor,2 multi-pin connectors next to chassis rail under plastic cover.These are the ones where they remain damp and corrode due to trapped mud/dirt.Remove cover and treat.Rear passenger wheel,top of suspension tower,multi pin connector treat.
You may have already found these connectors.
Goodluck,let us know how you go.

Why wouldn't you just spray every electrical connection under the bonnet along with those suggested ? Seems as tho it wouldn't hurt.

No Rob, They didn't... because they were connecting power instead!:pQuote:

All I could think of was that there must have still been power connected somewhere(DBS). I humoured him and let him go through his process. All I really needed was a spanner to disconnect the battery.Quote:

I left vehicle for a couple of hours then restarted now the transmission fault light, special programs unavailable and stability lights on again. This vehicle drives me nuts.
I'm going to source a scan tool tomorrow, any suggestions on brands and models.
I'm currently in Bundaberg heading north on our big lap of Aus but am stuck here until I get this sorted. If all else fails does anyone know a good LR specialist up here. Reports on local dealer here say they have limited knowledge on LR even though they are a dealer
I recall a thread some time ago where someone had a cable dislodged from the transmission by a stick whilst 4wding. Perhaps a the wash has done a similar thing. I'll see if I can find the thread...
Found it. Not saying this is your issue but there are cables/connectors that you could check around the Transmission and transfer case - after you check the compressor per Andy's suggestion.

LRS (Land Rover Spares) workshop in Mackay if you get that far and still have the problem.
