Need some info... 2002 Ford Explorer 4wd Not working
So my buddy's (who is not very net-saavy) 4x4 in his explorer is not working, no light comes on in the dash and won't shift into 4x4. So I offered to scan it for him using my Auto Enginuity with Ford package.
Well, found a couple O2 sensor codes.... but AE wouldn't read the 4x4 system.... said "communication failed" or something to that extent.
Would a bad 4wd Shift Control Module make the AE not be able to communicate with the powertrain and not be able to scan it?
