When I turn switch on ( no engine start ) the light of 4X4 will keep flashing all the time! When I start engine light will keep flashing all the time. ABS light also is on, when I scanned it, I found code of C1185 but I cannot clear it.
Any advice please. Thanks

There is no code c1185 there is 1155 and 45. See picture on how to fix it it may be a bad left front wheel speed sensor. If not then you have to check ABS unit to see if it is getting and sending power. Do not test the speed sensor with it connected to spindle it may fail if you do. See pictures.

For some reason I looked up the wrong truck sorry. This may be an ABS unit need replacing. See picture on how to check for that code. It will tell you very quickly the problem.

That may be a tie in with ABS problem if you scanned it and did not get any P codes may be the reason.

I am thinking about the transmission sensors. Do you agree with me?

No ABS can effect traction control and 4x4 operation. If you do not get any P type codes then it may be the ABS and until that is fixed you cannot tell. Or you can re-scan and if you get a P code then get back to us.

Good morning
but customer informed me that ABS light is ON long time ago,
4X4 light started flashing only one week ago.
So, I think There are no relationship between the 2 faults.
