Swapped to my winter setup: Warning light (DSC and ABS disabled)

Back to square one...

Took my X to my indy early friday morning as asked ,been waiting all week to get it in to get this problem fixed plus the oil leak. I was very exited to finally get something going.... So I wait til about 3pm and no news so I decide to give him a call and see what he found so far. Unbelievable: the car was still sitting outside and didn't even take a look at it. He said he would take a look at it Monday...Yeah right!
I took the X back home. I'm probably gonna end up taking it to the dealer , but I'll do the gear flip myself ( not putting the new one right away).

Good plan. Flip the gear and see if the problem persists, if it doesn't, you bought yourself some time and at least you know you have a replacement gear ready to go in.

If the problem persists after flipping the gear, you know you have other issues.

Good luck!

Update:

So I replaced the gear ( I couldn't resist and went with the new gear).

The 4x4 light (DSC) still turns on but AWD actually works. The system doesn't deactivates the AWD like it use to. The ABS works also now (and the light is off) . The only thing that doesn't work is the traction control. If I press the DSC button for a few seconds , the 4x4 light will reset and turn off but a few spins in the snow and the 4x4 light will turn on again and disengage the traction control.

I've also noticed that when I reset the DSC and have the 4x4 light turn off , if I just turn my steering wheel fully left , the 4x4 light turns on instantly.

I know I'll need to clear all the codes and see what new codes pop up but from the description above can we start pin pointing something?

Thx

You need to do left to right lock to lock to reset the steering angle sensor. Maybe that and a reset of the faults would put you back in action.

Rickey , I did the left /right/center but nothing happened. I guess my next move SHOULD be to reset all the faulty codes right?

[bcredliner]

Yes, clear the codes, I am not very confident that will work but if it doesn't the codes that return should be more helpful finding core cause.

UPDATE :

People who followed this thread remember I changed the actuator gear and it did fix part of the problem but after the gear swap , the 4x4 warning light stayed on and the abs on the left front wheel would activate for no reason (on dry) then the system would deactivate the 4x4.

Just got back from the dealer. Yes I went to the dealer again cause I went to an Indy last week and he charged me 50$ to tell me I had a problem and that I should have it aligned cause he saw the angle sensor fault and thought an alignment should be done first before doing anything else. So he sent me away to an alignment place and told me to come back after .....yeah right!
Anyway , dealer reprogrammed the steering angle sensor and voila , problem solved.
They think someone played with the steering wheel while the car was lifted and key in position 2, OR ,another tech said it could be because I changed the actuator gear and for some reason the position changed and sensor couldn't figure it out and "invented" new specs. But left spec was way off according to the angle sensor. They charged me 1hr no parts.

Thanks to everyone who chipped in....

Wow, never would have guessed a wheel speed sensor could throw off the angle sensor...glad you got it fixed!

Angle sensor was off....not sure I understand why you are referring to the speed sensor.
