Thread: A costly mistake, please help!

Heat shrink sounds a bit extreme, if you mean encasing the entire ECU / plug in a huge tube of it... Not to mention expensive.

If you must, then use 'Self-amalgamating tape' around the plug/socket/harness. - name says it all, it bonds and fuses into a single mass when applied under tension... Again, not overly inexpensive...

Easier way is to keep water OFF the ECU and the plug. Fabricate a 'roof' or umbrella or whatever, so next time you hose out the battery...no water actually reaches the ECU etc.

Australian Mini-Minors would always stop in rainy weather.... water-spray covered the distributor. Common fixes ranged from carrying dry rags and CRC.... to making rubber gloves to totally encase it all.

English Minis never stopped.... because they had a simple, cheap plastic shield that intercepted the spray.

BMC (later British Leyland) never thought 'water' would be a problem in a super hot & dry country like Australia... LR seem to think the same.

- Keep the water away from the Delicate Bits, instead of trying to make them waterproof....

I agree 100% on this.

Hi,

I have a very similar problem and need some help please! I also made the mistake of pouring water on to the negative terminal of my battery causing the fault message "range change not available".
On the recommendation of a landcover specialist (who unsuccessfully tried to dry out the transfer case ECU, i purchased a new ECU and had that fitted by my local mechanic (I live 1 1/2 hours away from the Land Rover specialist).
Now the vehicle is permanently in low range and the symbol on the dash is flashing, the same message about range change is on the dash as is 'special programs not available".
Before I start looking for another problem, I'd like to know if the problem may be that ECU needs to be programmed, or shake hands with the vehicle and if so, which diagnostic tool could do it, or will I need to organise a trip to the specialist again?
Many thanks,
Andy.

A self-calibration is required for the transfer case ecu / transfer case. It is initiated by a particular diagnostic command to the TC ecu via the OBD port.

I was advised a couple of months ago by Gap Diagnostics that their IID tool (Bluetooth version) recently had this capability added for D3s. My Faultmate MSV does not have this capability and BBS have stated that they have no intention of providing it.

Thanks Graeme. Does anyone know of any other possibilities to reprogram the ECU or is this it?
