AFS Light Flashing: Bad shocks to blame?
Been waiting for suspension parts to arrive. Took the car out today and out of nowhere the afs off light starts blinking. Would the rear shocks needing replaced cause this since the sensor is located back There? I haven't touched anything. Sensor looks intact.

probably worn out headlight leveling sensor
There are many AFS flashing threads on here and how to repair. Here's one of them... https://www.clublexus.com/forums/ls-...afs-light.html

Not likely. Most likely 1 worn out (out of 2) auto-leveling sensors on the driver's side of the vehicle. There's 1 at the front driver's side wheel/suspension, and 1 at the rear driver's wheel/side suspension. They don't last forever due to the rheostat/circuit always moving as the the suspension moves.

In the meantime, your headlights will probably default to a very 'low' aiming/position.
Good luck!

I saw those but many people said they only lasted a few months and burned out prematurely. I may buy one of those and put it on my stock linkage as a spare for down the road. the lexus oem lasted 12 years and 95k miles so I won't mind spending the money to not ever deal with it again.

with the new sensor i am going to apply white lithium grease to all pivot points on the linkage and then around the sensor housing. ive even thought about wrapping a balloon over the sensor for an extra seal. i have the whole sensor removed in the meantime and zip tied a ziploc bag around the connector to keep any dirt and moisture out.

Can't be sure about where/how moisture gets into the sensor, but:
the two I've fixed seemed to have moisture entering through the electrical connector leads; they are molded into the housing, but apparently that isn't moisture proof.
The poor conductivity has been between the springs (corroded, both times only 1 of the 3) and the brass contact down in the spring hole which is actually the end of the male lug that passes out through the housing.
Solution has been to clean up the springs and the contact down in the hole, stretch the springs a little for insurance, and finally confirm connection with an ohmmeter before putting the cover back on.
Then, for what it's worth, I pack the electrical socket with dielectric grease before plugging the harness back in.
This is a place Lexus should have used those moisture resistant plugs we see elsewhere around the car.
(The o-ring that seals the cover is surely not the issue; it's identical to what I work with for a living, and I feel sure no moisture is getting past that o-ring.)
It feels great to avoid a $300+ part replacement for 20 minutes of work in the drive
I haven't seen evidence of moisture getting in through the rotating arm passage either.
