    I've searched the forums but couldn't find anything on this or just missed it so I will apologize in advance.

    I replaced the skid module with a junkyard unit because the abs solenoid was off. After learning it is inside the skid module I swapped the junkyard one in. It works. The abs and brake lights went off. I had another spare unit I grabbed with the same part number to be safe. No matter which unit I plug in I get the C1340 open circuit center differential lock signal.

    I had a spare translate ecu module and it changed nothing(same part number as well). Weird thing is every single part of the 4wd system works. 4 hi , 4 lo, diff lock engage/disengages. All indicator lights work perfect with no flashing.

    My question is where does the center diff lock signal come from? Is it part of the transfer case shift actuator on this newer model?
    There are no plugs anywhere else on the transfer case besides the speed sensor in the tail shaft.

    Any help would be greatly appreciated. Thanks in adavance.
