Hello. Welcome to Just Answer. Please allow me to assist you (sorry about the delay/having some bad weather here). More than likely, your ride height sensor at the driver rear suspension is faulty or the wire connector is corroded. We see this quite a bit on this vehicle these days. Age, dust & water contribute to this common problem.

The system corrects itself once the car is turned on or running. If it were the sensor wouldn't it "not detect" when it is low?
Expert:  Toyota Service replied 1 month ago.

The sensor determines where the height needs to be. IF the system corrects itself when started, the compressor is bypassing and the sensor is OK. When the compressor bypasses, this allows the system pressure to recede back into the compressor. Soap the compressor. This is where you will probably find the issue.
