Seat Memory

[Fergus the dog]

Hi all Lexus LS400 Owners

I just purchased a 194 LS 400, knowing that the seat memroy doesn't work, althought the electric seats / mirrors etc do.

Does anyone out there know what the problem is, I assume there is a memory chip somewhere on the car.

I'm awaiting a workshop manual / CD

Thanks

you have the 2 buttons and the set on the drivers door,

set the seat for driving position and mirrors/ steering wheel,

press the set button and hold then button 1 keep held till you hear a beep to confirm its stored,

now do the same with button 2 but obviously for exiting the car,

ignition has to be on but engine not started

Thanks,

However I know how to set them, the point is it won't do it, it doesn't bleep

Check the fuses on the junction block on the right near the drivers feet

Check that the 'dome' fuse is OK .....this is in the big fuse box under the bonnet

The power seat ECU is shown as on the floor under the seat.

Memory info is sent to it from the tilt and telescopic ECU shown as under the dash just behind the wheel.

There is also a position sensor on each motor.

Hope this gives you a clue where to start!!!! :duh:

does the auto steering work ok if not it has an effect on the seat memory?? are you pressing the break peddle while trying to set the seat memory up if so "don't" because it wont set up?? are you turning the ignition on full without starting the engine if not you cant set the memory up.

im new to the Lexus even though im a mechanic and the electrical thing are tricky but im getting there

Hi

Thanks for the response, the auto steering works fine, like all the other electrics, only the memory isn't.

Also doing exactly what you say regarding setting the seat positiins etc
