Here you go guzzy, hope this helps. 08 GS350 no current code, but B2416 height sensor control in history.
Thanks a lot Rick!! You know I cant read the trouble codes on my car with TS despite it says 4 for the number of trouble codes, when i try to read them i get:
"Error Code: 0x91020324
It's possible the requested function will work if you try again."
I can see you have 1 code, TS let you read the code?
Run the Health Check on the main screen. All DTCs will be displayed on the Health Check Results screen. That's where I got mine. Still learning the TS software, a lot to learn.
Thanks a lot RICK!!!! will check all that, first try to pull out the codes and then check the connections to the AFS ECU to see if I have a faulty module
Alright, finally got to pull out the DTC code thanks to my man Rickdestik! I have the code B2416. I found a pdf to troubleshoot it and see what could it be, crossing fingers not to have a bad afs ECU.
Rick, you mentioned you had this code in history, how did you solve it?
Code in history means that the code occurred at some time in the past, so nothing to solve. No info on when. What ever caused it was resolved. That was the 1 code in the data that I posted.
oh, ok! I thought that code was thrown when the car was in your possession. On the weekend I will try to solve the issue checking the condition of the AFS ECU and the sensors themselves. I am wondering how much will that AFS ECU cost, I cant find it anywhere.
Btw, thanks again for the TS tip! learning new things from hat software everyday!
List of computers for 08 GS in the following link. Everything is in alphabetical order and headlight computers (yes there appears to be at least 3) are about 80 items down. None are cheap. Go further and check the seat belt and steering computers - ouch, but everything from the dealer is expensive. BTW this is in the Electrical/Switch & Relay & Computer area of parts.
I would check the height sensors first as they are external and in the elements. Something could have happened to the height sensors when tire, brake or suspension work is was done.
Good luck and let me know how it turns out as I may be dealing with a similar situation one day.
Issue was easier than I thought, happen to be that the rear height sensor lever was positioned in a wrong way by previous owner or who knows, making the AFS ECU read a constant 4.5V value no matter the position of the suspension.
Anything above 4.5V from any of the sensors is going to make the AFS ECU to throw an error code, more likely the B2416.
If B2412 or B2413 trouble codes are being read, its most likely the sensors are not working or there is a short in the line and sensor reading is 0.00V
Here is the Rear sensor value when the AFS LIGHT BLINKING was happening:
This is how the sensor lever was positioned when reading constant 4.5V:
And this how it should be, with the lever elbow pointing up!
And this is the reading from the rear sensor after installing it right:
So happy to see my dash like this, no afs off light blinking!
Next step is to find a flat surface where to park my car and tune the front and rear lever position, if it helps anyone here are the values to be expect from both sensors according the the lever angles:
Front sensor, located at the front left wheel area:
Rear sensor, located on the left rear wheel area:
And finally, here is a document to troubleshoot the AFS system, hope it helps someone in the future:
I understand that your issue was different than mine, but since you spent so much time troubleshooting, I was hoping you would have an idea or could send me down the correct path in fixing my afs issue..
My lights do not level (didn't even know they did this) when starting the car. The afs light does not come on or blink and appears fine, until I turn the steering wheel, then the afs light starts blinking and continues to do so until the car is turned off. The stored codes that I did get through techstream are B2412 and B2413.
I have access to Techstream, but do not fully understand the software or what I should be doing. I did a live data and did notice that no matter what the value for "steering sens center pos" did not change at all and stayed at -9.0 when moving the wheel.. As far as I could tell, I was unable to move either left or right lights, I tried clicking them on through the live test, but they wouldn't switch from off in techstream, same thing happened when I tried to level them.

what model/year GS do you own? Did you ever replaced the headlights? Have you removed them from the car to be sure you have the swivel motors? I would make a test trying to move them with TS to see if the motors are connected or present.
