hehe, be careful its not the stuff telstra use to use years ago, which ends up corroding the connections

Hi People,
Well I did the reassembly thing with little success, the faults I had before are the same as when I took things apart, one thing different the faults now are consistent, before they were different giving off different symptoms every five or so minutes. At one point I thought I nearly had it then (last night) everything went back to where it was originally. I cleaned all the connections as best I could, dried everything out and tried to reset the fault codes. gearbox is all clear the problem is all around the trasfer case or at least appears to be.
Is it normal to "toast" the module when this electrical fault happens or is it normal for it to recover? The fault that won't reset is the clutch reading is high, can't remember the exact wording.
Thanks in anticipation for any help rendered, the forum is doing really well so far.

When you say 'faults' - are these the normal messages reported by the car, or do you have a diagnostic box plugged in? Diagnostics would (hopefully) quickly pin-point the offending module. If you're still under warranty, take it to Southerns up the road and get them to diagnose it for you. If not, you could try Kevin Falconbridge at RoverTech in Bentley - he has the Autologic modules for the D3.

Yes, you could fry the TCM if it was wet for a period of time. You'll have noticed that it isn't completely sealed.

Cheers,

Gordon

Sorry Nomad never got your PM.

Try to make sure it is really dry (use SWMBOs hair dryer )
I coated mine with CRC Plasticote as haggis suggested.
You can seal it better if you take it out. Then coat the connectors well when all is working.
A fair few of these modules have been fried, some by the dealers which is why the LR moved it in the D4.

Hi Caver D3,
Not sure what happened to the PM, lost in IT space somwhere I suspect. I dried everything out I left the module in a warm place for 24 hours (upstairs in the loft I know what people might think!!) I connected everything up and I had the same fault, prior to drying everything out I was getting different messages flicking up, sometimes the LED would come up and tell me things were happening, next time I switched the ignition on as soon as I started the engine the little light on the selector would go out and a message would come up telling me the special programs were no longer working.
After drying everything out and cleaning everything up all I get is the little light lit up by the selector at the position two of the ignition key as soon as I start the engine the light goes out and tells me the special programs aren't available.
I've hooked up my Faultmate MSV-2 this tells me the fault is in the transfer case somewhere, all the other modules are fault free. After the assistance from Gordon aka GGHaggis I learnt about the transfer case module, then I found the terminal box connection immersed in water and a gooey silicon grease solution, all very yuk I thought I had found the problem, I still think I have but I belive the module is rooted, TRS in S.A. are sending me over a reasonably priced transfer case module to replace mine, this way I'll know for definate what the problem is and maybe recify the problem.
I have my D3 booked into Southerns a week on Friday to get the wheel alignment checked and adjusted, if things still aren't right I'll ask them to have a look. I'm hoping things will be near rigt by then. Interestingly the module I took out appears to have been replaced late last year. I only bought the vehicle from a person in the ACT in July, I suspect he may have got things a little wet.
Really appreciate the help from you guys, you've been very helpful, hope I can return the compliment one day.

Yours Marty
