Wow... more issues? My M37S has been relatively trouble free. Much more reliable than my Volvo was. Glad to help out!

Interesting. I have not replaced a single bulb on my M37S.

Replace the actuator with the M35 actuator I bought from eBay and the lights are off. Drove 7 miles no lights.

So my steering wheel is slightly crooked, should I get an alignment done tomorrow?

If the light does come back on let us know because you calibrate the rear steering angle sensor yourself. You have to line the sensor up with the slit on the actuator, then while your multimeter is connected to the cable pins turn the sensor. The values should change and you just have to get them to read 2.4.

Update on my 2011 M37S $WAS issue:

(1) I took my car to an independent shop who has the ability to calibrate the Front Steering Angle Sensor.
(2) They calibrated it and cleared all Codes. Drove the car 30 miles. No Codes.
(3) I am pleased to say the car is fixed! I have driven it an additional 45 minutes or about 25 miles.
(4) The real problem was the Front Steering Angle Sensor Connector. It must have been bumped loose. I disconnected it and reconnected it and I was able to clear Code C1930.

Infiniti Motors and my local Infiniti Dealer should be embarrassed that they wanted to first replace the ABS Actuator and then the Rear Steering Rack. Neither would have fixed the problem.

I have found a reasonably priced Code Reader that can Calibrate the Front Steering Angle Sensor (and a lot of other stuff). It is made by Autel and runs $350 or so.

Thanks,

Happy M37SJoe

Want to thank everyone on this forum....my 4WAS on my 2011 M37S recently failed, but because of this forum, it was not costly or challenging for me to have repaired.

Before I bought my car in September of 2019 (had 96K miles on it) I did a lot of reserach on it (here and elesewhere) and as a result of that I did something I never do....I bought an extended warranty. This car is my commuter and as such, I didn't want any hassle or time spent for me wrenching on it (I have MANY more vehiciles that occupy that space for me). For $2500 it covered me for 5 years or 60k miles. Car has been trouble free for almost 40k miles and the past 2+ years.

Until about 8 weeks ago. I started getting intermittent dash lights on for the 4WAS. Would come on, then go off. By the way it was driving could tell it was failing. Additionally, my driver side power mirror wouldn't fold in or adjust and was loose. I took it into the dealer, they diagnosed the rear steering gear/motor assembly was bad. Warranty company honored it and along with the mirror repair and alignment....all it cost me was my $100 deductible. Cost the warranty company $10,750. After having it for 3 weeks, I got it back from the dealer on Friday. All fixed and good to go.

So thank you to this forum!!! And if you can....at least for this car....buy that warranty!!!

Carry on gents.....

Thanks!

Mine came in at
1-4. .93
1-2. 1.27
1-3. 1.27

I have codes c1138, and c1130 if any one can point me in the right direction it will be much appreciated. I removed the motor from the steering rack and ran current to it and it spun.

Hi guys , I purchased a used M37S 2012 about 5 month ago from a guy who has the car for 2 years and he doesn’t know nothing about the car . So when I got the car he mentioned something about the light (4Was) and he said he never was able to figure it out.
When I got the car I jacked up the rear end and I have removed the cover off the motor ( hicas motor located on the back steering rack) and cleaned it up and nothing really happened the check engine lights stayed on and then I went on eBay and I found a complete rack with a motor and everything was good condition bought it and installed it and I still have the light on and my steering is about 15 degrees off to the right . I did a complete alignment on the car and then the light went away and the light will come back only after I drive the car for like one minute but when I turn the car off and turn it back on the light will go away until I start Driving but now about a week ago the light will always stay on and the steering wheel is off always .
I love the car but it’s really starting to get to me especially that no one really has a good diagnosis method to start somewhere . Any help would be extremely appreciated
The codes are :
P3800
C1138
P0209
I have a suspicion of the front HICAS steering shaft but I don’t really have a good way to troubleshoot it.
Is there any scan tool out there can actually troubleshoot this system besides the factory scan tool ??

I never used a multimeter. I attempted but did it wrong so I gave up. I aligned the sensor with the slit in the actuator which ended being North and South angle. Then I turned clockwise (reading your post, so thanks) slowly a bit and then started the car. I kept turning and starting until the lights were off, lol. Trail and error. I plan on making a YouTube video as I still have the cables and M35 rack with motor so may help someone. Got 4 wheel alignment done this past Friday at the dealership. Still no lights. Thanks for your help.

Hello bud ,
Have you made a video yet ?
