Has anyone ever taken out the ECM of the LR3

Battery gone! -- Check
Cover plate over Transfer Case ECU -- Check
Unplug the Transfer Case ECU and remove -- Check
4 5.5mm Screws holding the ECM housing in place --- NO WAY

If anyone has done it, how did you get the lower right screw out?

A ratcheting 5.5mm spanner? I do not think that would work.

 

 

Also, how do you take apart this wiring connector?

 

It has been awhile since I did that, but as best I recall try these:

For the bolt: I used a short 1/4 drive socket, a universal joint and a short extension with a ratchet
For the connector: Pull out (or raise up) the big red thing then you should be able to press down on the retainer clip like most other connectors

 

tried just getting a socket on it with universal joint and could not fit it between the bolt/screw itself and the body.

might need to get a little angle wrench and slowly back it out. Issue is, if that screw is the same length as the other screws, it will hit the body before completely backing it out.

I have no idea how they even assembled it.
