Hi folks.
I recently got myself an RX300 2004, which has a suspension fault.
The symptoms:
The height is stuck at its lowest.
The green indicating light on the dash is a neutral. The height selection switch does nothing to change this.
When I turn the ignition on I don’t hear the pump running.
I intend checking if the pump is getting any electrical power, but I’d like to know if it’s always powered when the ignition is on or just when needed.
This then leads me look for a relay that it’s powered through. I assume it must be as it’s quite a heavy motor.
Hi, it is difficult for us to help as this forum is mostly Americans, and we never had the air suspension, and a lot of the service manuals sold here do not cover features unavailable here. I will see if I can find any schematics for the air suspension. Could you post a picture of the button that is supposed to activate it? It may be easier to find a schematic for the air suspension of a LX or GX.
edit: it looks like I misspoke. Air suspension was available it seems. You may find some info in the following thread:
I've now managed to trace the + side of my relat to the connector behind the panel in front of the driver's knee.
It's a direct wire on to the ECU with no other connections.
I've concluded that the ECU must be faulty, so decided to look for a replacement.
This has given me another issue.
My part number is 89293-48012 but the part I can get is 89293-48013. Note the last digit.
Can anyone tell me if these are interchangable? Mine is from a 2004 and the later is from a 2007.
It is too expensive to fix air suspension on such a car,I did replace it with regular strut/spring kind and all good to go,it was plug and play no need for modifications,my car is 2004 RX 330 USA model
