14 Sport - AWD Error P188B

[6JEFF6]

Well can add no awd to the list.. Had to take it to work and found out... put in snow and ice setting and as soon as tire spun no awd error .. this thing is going to be a battle

Is Traction Control switched ON? I don't know if the condition you mentioned would produce an AWD error if AWD was actually working.

Peter

Never played with it so I'd assume yes

Traction control comes off for mud/rut mode, sand mode but is on for snow, gravel and grass and also normal driving mode.

Error P188B

Here is what I found on that DTC code; P188B - Ford Diagnostic Trouble Code (DTC) Definition, Causes and Diagnosis

Ran the test from this link(here) '14 Explorer Code P188B AWD Clutch Control Circuit Issue

And ohms on 1st test failed and came in at 1.8 ohms so ecu for awd is shot.. will have to use junkyard, new is not available anymore.
Part # bt4a-7h417-eb and will hopefully buy one from junkyard on Monday and will post back

This is what I found out.
Will update when I get it Monday or Tuesday

Did not fix it but I did do the procedure wrong and tested the relay not the other way like the instructions said to do..... may take a bit before I can test again but I will check back with the fix if I find it

 

[6JEFF6]

Check that procedure done absolutely correctly as I pulled cover and rechecked what I did so idk why it would give 2.0 ohm and be not the module as it states it should be.. setting on meter was 0-100k.. guess I'll keep checking maybe 2 things were bad.

 

[6JEFF6]

Odd. Put in and didn't work right away.
Then yesterday it worked a few feet than awd off came on so going to drain ptu and fill.
75w140 synthetic?

 

[6JEFF6]

I won't start a new conversation but hopefully someone will answer...

Changed fluid and put in mud and it jumps/grinds/bucks in rear so I'm assuming it is the rear viscous coupler but cannot find it for sale anywhere? Any input?

Any help would be greatly appreciated

When you said "put in mud" I'm guessing you are referring to the TMS (Terrain Management System) selector? Reads like you changed the fluid by putting mud into it.

Haha ya 75w 140 full synthetic...
Only thing I found for it is a whole center section rear differential from a junkyard for $243 so I bought it.. all parts have been discontinued.. the part seems replaceable so odd it isn't available at all?.. be a while before I put it in though

 

[6JEFF6]

Finally put it in and absolutely perfect... not a terrible job but my dewalt guns were a lifesaver.. now to get the state patrol to release my title...(bought in MN and dealership had fixed from salvaged but never retitled so when I bought it and applied for wi title it needs wi inspection eventhough I had all paperwork etc...)
Never ending fun

Hope this helps someone
