By the driver's rear tire where the sway bar bolts too there is a sensor for ride height, it should be vertical and upright. Check the harness as well. Slight slight possibility that may have shifted the sensor, maybe an undercarriage wash might have made it rotate on the joint. Worth the look

When I lowered mine the Check headlight system warning light came on after install. I checked the sensor in the rear but it looks fine to me. Below is a pic What do you think?

After a couple of cups of coffe, my hands were itching do do stuff, so I jacked the rear up pulled the 20mm spacers off pulled extended lugs off, rolled both rear quarters and installed the back wheels
couple of bottom wheel pics have 20mm spacers on the car, it was too much for me

Sorry to drag this one back, 2011 ISF here.
- Had this issue yesterday right after washing the car.
- It also happened once before 4-5 months ago during a heavy rainstorm, but it went away after restarting the car.
- No suspension changes, so in my case, it is due to something getting wet due to a car wash.
Car is on OEM shocks and struts, no suspension modifications.
- Headlights, turn signals, high beams, fog lights all function normally with the error.
- Checked the front and rear sensors and they are set according to the diagrams above and in other posts.
The sensors have not been moved/touched for months after moving the "rear sensor" so that it points higher than stock.
Set the rear sensor to the "middle" mark and issue remains.
Disconnected car battery, issue remains.
- Photos and videos of the issue attached.
Video of issue:
Checking if anyone else has had this issue? The issue only presented itself first during a heavy rainstorm when driving around. Then again yesterday after a car wash. Didn't do anything different nor have changes done for months either.
So was wondering which "electrical" part needs to be looked at/replaced.
Thanks for anyone's input.

Did you inspector the connector and wiring that attaches to the sensors arm.??
It should unplug, can't remember.. If it does and checks out OK.. See if you can apply some connector grease to keep out moisture or etc.. Also try to trace the wiring harness..
