I folks.
I have an RX300 2004 on which the suspension won't raise.
So I tested the relay whci was fine (I have 2).
I then tested the pump by shorting the relay connections. Pump works fine.
I replaced the ECU for the suspention, but still the suspention won't run the pump.
I have diagnostic software but there is no fault showing.
I've removed the battery power for 30 minutes.
I've taken ALL of the level sensors off and cleaned inside them and also checked them using a multimeter. All the values were the same.
I've checked all the connection to the sensors.

Still after all this, the pump won't run and I get a light on the dash flashing AFS (Automatic Froantlight Sensor)

Does anyone know of a solution?

to check this sensor first.

Dingus

Sorry iMSQ I don't understand your post.

Dingus

I should have said. I have AFS flashing on my dash.
Only think I haven't checked is the over pressure switch on the reservior.
Now I need to find the tank.

IMHO, car body leveling system (as well as headlights auto-leveling) will be turned off if any level sensor has died

Dingus

iMSQ. Thanks for that. I thought if one died the other 3 would work, so haven’t look at that option.
This at least gives my something to try.

Thanks

iMSQ.
I just had another thought.
Does the ECU look for a good signal from each sensor? If so I could disconnect each one in turn to find the faulty one.
However, if it doesn't I'd need to investigate in a different way.

Usually, there are 2 body level sensors in a car.
