please helppp....

2006 explorer 4.0 abs, rsc lights.

i had some times abs and rsc lights come on and car brakes by itself as traction control activate at normal driving and got b1676 and c1175.

after some time both lights abs and rsc lights keep on and only c1175 which is rear left abs sensor circuit faluire.

changed the abs sensor with new one and same problem still there.

i've checked the abs sensor connector self test voltage when turn on ignition its only 8 voltage.
other abs sensors is reading 12 voltage.
so may be poor abs module connector contacts.

tried to disconnect the abs module connector but cannot.

please help how to disconnect it with photos please if possible.

Please don't ignore and Thanks alot in advance

i changed the sensor it self but same problem still there....
when turn on ignition, abs module send self test voltage to each sensor to check it, for all 12 volt but for this sensor its only 8v so poor contact in abs module connector but i cant remove it to clean it....
please help....

So poor ground contact maybe /....
What I meant is that in the rear you have ABS tone rings on the half shafts. If one of them is cracked, it will cause similar issues as well. Rotate the shaft and observe for cracks.

i already checked the ring on the cv joint but it seems good....
using the obd2, the abs senaor reading is qorking fine for the other 3 wheels, but zero for the left rear and got c1175.
thats why i think its the abs module connector poor contact inside.
but unfortunately cant disconnect it.....
