AFS malfunction
Hi, I've got AFS issue, error code B2416 - the system is not working, AFS OFF light flashes on dashboard.
- Firstly I replaced rear AFS sensor because there was no voltage reading for it and a wire harness aswell (also fixed existing ABS issue instantly).
- The voltage reading for rear AFS sensor is back. AFS OFF still flashes.
- Secondly I replaced broken front AFS bar. No change on dashboard.
- The AFS OFF light still flashes and the readings from ECU are as below. Anyone can advise where to look now ??

1.The rear sensor showed the same voltage values despite the car was being jacked etc. and the front sensor values were changing properly along with car position.
2. I checked the mechanical connection: rear AFS sensor vs lever. And I found it: while I had changed the rear sensor earlier I did not properly attached it to the lever (there is this rectangle shape connection between lever and the sensor + nut).
3. The rear sensor sent constantly 4,5V signal which was read as an error by ECU = AFS OFF error.
4.After proper attachment the AFS error is gone! Solved
There is a very useful topic where I found clues where to look for and propoer values for voltage signals: https://www.clublexus.com/forums/gs-...50-07-a-3.html

I simply started the car, and pulled the AFS fuse as the car is running so the lights point straight. To me i feel its useless option, once you pull the fuse, the light on the dash goes away. But if you pull the fuse with the car off, then the lights will point down
