Thread: What have I done and how do I fix it?

Search for Hard Reset on this forum and follow the instructions

Thanks Tombie, but tell me more, tried searching with no results.

I know what you have done, when you pored water on the terminal, water has gone down behind the battery and wet the tranfer case ECU.

If the hard re-set doesn't work, you may need to remove the battery and dry out the Transfer case ECU.

A hard re-set is disconnect both battery terminals, touch them together then re-fit them.

Oh and if you have a second battery, disconnect that before you do the hard re-set.

Hard Reset Instructions

In brief, to start the hard reset process, open the hood but close all doors and let your 3 go to sleep - no radio display etc and no key in the ignition. This will take a couple of minutes and do not open any doors until the reset is completed. (I find that it is often a good idea to have the drivers door window rolled down and the key in my pocket whenever fooling about the vehicle.) Also when I play with a car battery, I remove any rings I have from my fingers; also my watch.

Disconnect the ground battery terminal from the main starting battery.
Disconnect the positive battery terminal from the main starting battery.

The reason for this order is if a wrench or loose battery cable ends grounds to the body, no arcing or other bad things happen.

(I assume that you only have one battery in your 3. If not, disconnect the others as well and leave them disconnected until after all is done.)

Connect the negative cable to the positive cable. (NOT the battery.) You will need a short length, (a foot or so), of light gauge, (14 to 18 gauge AWG, insulated stranded copper), wire to span between the battery cable ends as there is not enough slack in the positive and negative battery cables for the ends to touch each other.

Hold all together for about a minute or more, (at least two minutes), as you are discharging memory modules within the engine computer and elsewhere. Then it is suggested you then just let all sit disconnected for say ten minutes, (minimum five minutes), prior to commencing to put the battery cable ends back on the battery posts per the following order.

Reattach positive terminal to the main starting battery positive post.
Reattach negative terminal to the main starting battery negative post.

Start engine and hopefully no or fewer warning lights.
Reset time on the radio - note that the station presets are still there as not everything is erased. Nothing much else needs resetting either.

You can now connect up the other batteries if you have a multiple battery setup.

If you have an Aux battery system - don't forget to disconnect that negative terminal as well - Don't want back feed

I did the exact same thing a couple of years ago and it did not end well ended up having to replace the ecu about$550 due to water making its way into it I would suggest going straight to the ecu and pulling it out and getting it dry as soon as possible then replace it and do a hard reset. Your location is not idea especially with all those sandy speed humps on the way to the main road. Best bet is to start looking around broome.
