I just got this 2000 rx 300 a few weeks ago and ever since I got it; the drivers seat memory has not functioned correctly. It will not retain memory settings correctly. Every time i set it up; then press each of the 2 memory buttons; nothing happens. What can i do to try and resolve this? Is there a way to reset the controller for the memory to see if that will resolve this? Or could it be something else more complex that I may have to shell out big bucks to a dealer to fix? Thanks, Matt

Just to confirm, you are saving the seat settings by holding the "Set" button and then pressing either "1" or "2" correct? Do you hear a beep confirming it saved?

matts6887

Yes, i do hear a beep/tone to confirm that it supposedly saved; but yet; when i press the 2 different buttons; nothing happens.

You need to be in Park to recall the setting.

If it fails try disconnecting the battery for about 20 mins. This will wipe out old seat and radio settings too. You can try to reprogram and see what happens.

is there any way to wipe out the old settings without disconnecting the battery? as i would rather not have to go through and reset the radio presets again if its possible to avoid doing so.

with the Key in the "on" position and not have the brake pressed.

What about this?

salimshah

If some one knew, they would have responded. Setting radio again is inconvenient but not hard.

Anyone have any ideas on this also other than having to disconnect the battery to reset the memory seat controller?

Afraid not... Mine stopped working shortly after I got my RX, and the only real fix is to replace the seat memory computer mounted under the drivers seat. Kind of a pain, so I've learned to live with the lack of seat memory. You can try pulling the ECU fuse. It uses the dome light 10amp fuse and the 15amp ECU-IG fuse.

Where are these fuses located? Are they in the engine compartment like on some vehicles; or are they inside?

Also; in terms of the seat memory computer; how can i get access to this to maybe at the very least inspect the wiring and maybe see if a wire(s) are possibly crimped somehow or there is a loose connection or something of the like?

2KHarrier

Look at the fuse block behind the coin compartment, to the left of the steering wheel. Pull that little compartment out, and you'll see the block back there. Look at the diagram to match up the fuses.

The seat ECU is under the driver's seat. You have to remove the plastic shroud from around the seat assembly, and then you can access the ECU and it's harness. I have not physically removed it, so you're venturing into uncharted waters here.....

Thanks. I will take a look when i have a moment and see if i can get it to work at all. I would rather not shell out big $$ at a dealer to have them get the part for me if i need a new one but i dont see any alternative unless someone else has any ideas.
