My 2004 ls430 has had the AFS light flashing off and on for the last few days.
The manual says see the dealer. Has anyone one else had this happen with their LS???? What was it ????? what did it wind up costing?????

I had that problem once and posted it. It ended up being the rear leveling sensor and cost me about $400 to replace it. After seeing the part and what was replaced, it is an easy do it yourself job if that is the sensor that is causing the problem. Mine was clearly burned from heavy snow and rain.

Funny, I had my sensor replaced just yesterday.
The sensor is located on the LH side (driver's side) of your rear control arm.
The part cost $450 Canadian.
My wiring harness had a broken connector, so my mechanic had to take extra time to
fix the connectors. He packed some extra grease in there, to help keep the connectors stay dry from snow and water.
Total cost was around $525 Cdn.

Interesting, my headlights came back to the correct height.
When your rear height sensor is faulty, the computer automatically aims your
headlights really low. The new sensor makes a huge difference in night driving.

Good luck ... that flashing light is a pain, as is the low headlight beam that
accompanies it. As everyone has said, its an easy fix, but most of the cost is
in the part, not the labour.
