Rained for 24 hours and the weather changed 10 deg, 4lo warning is back.
What I’ve learned / looked into- I looked at the pics in the fsm, the 4 lo is the lower of the two powered actuators.
The center diff warning is different (flashes the center diff light, not 4lo light)
When it was off earlier in the week it was raining , so I got the center diff working. It continues to actuate even when 4lo is blinking.
So - If the 4wd computer is the boss of both, it is probably not an interior leak as root cause.
Most of the tutorials seem to focus on the upper / differential actuator. I’ll need to lookup some beta on removing the 4lo lower side of the actuating box.
I really wish this stuff was all mechanical. I haven’t gotten into it yet, but there aren’t that many pins in the plug, it seems an arduino and some linear actuators to drive the rods could be hacked in there.
