Guys - I really need some help here. My rear struts needed to be replaced and I didn't want to take it to the dealer - I thought I might save a few bucks going somewhere else - how hard can it be to replace struts...?

So after the shop finishes with the struts, while I'm waiting on the car, they tell me they're having trouble resetting the AFS system. Eventually, I learn that the problem they're having is that the AFS OFF light is blinking.

You can turn AFS OFF on the drop down panel left of the steering wheel. But the manual indicates that if the light is blinking then the system has failed.

While they're trying to figure it out, the driver side headlight bulb goes out. Replaced that ($175) thinking that might be the AFS problem. But no...light begins blinking again.

Anybody had this issue? Is there a way to reset it? Any way this could be related to replacement of the rear struts (with adaptive sport suspension system...)

Any input would be appreciated. I'm probably going to the dealer now - but if anybody has any idea what's happening here, it would be a big help!

Thanks,
jasontucker
Update here... Nobody responded but I thought I'd post an update in case anybody else runs into this... I found some info on this forum for similar problems with some LS and RX models. They all pointed to a faulty ride height sensor that is attached to the rear axle.

Since I just had my rear struts replaced, which so happen to also be connected to the rear axle...I thought I'd take it back to the shop and have them check the ride height sensor.

Problem solved... When the rear struts are removed, the rear axle dangles. When it dangles, it pulls down on the actuator arm that is attached to the sensor. When the new strut was installed, the arm went down rather than back up. (i.e. picture an elbow that should be bent up and to the right being bent down and to the left).

Makes the car think the rear end is dragging the ground...

Disconnected. Reconnected correctly. AFS OFF light is OFF!!! Whew...

Congrats to you, I know the feeling on trying to save a buck then to have the sensors go a-wall.

Had the same problem when I had the brakes replaced. After I changed I had to take back to the dealer to have them reset sensors, still cheaper then having dealer replace breaks, but I almost had a heart attack!
