Hello . My car ls400 ucf20 2000year.

From one day the power seat, lock, unlock, side mirror, and electric handle are not working.

Memory seats don't work either

The trouble code is left hanging as in the bottom.

B1211 B1212 B1213 B1214 ..

Ask what is wrong and what is diagnosed.

Please understand that the above is a translator.

Which fuse should be checked?

I think I find the answer of your problems but I need to confirm it using my own car before I inform it to you because I only analysed it in the circuit diagram. As I see the diagram there is a common item which causes all of your problems simultaneously.

Incidentally was your problem below already fixed?

Please understand the translation machine.

Thank you for your answer.

As a result of rework of timing belts, existing P1346 code and check vsc are completed.

I have read your articles.

I plan to check it out on Monday with an Obd scan and I feel it is a problem with the multi plex network door computer.

Does the door trim need to be removed and checked?

Or should I check the bottom fuse of the dash?

Please advise me that it is too hard.

So your P1346 issue was caused by the off timing. It would be nice of you to post what was the problem to close your post. A good member here does so always.

Regarding your current problems, I worry that those were caused by some incorrect job while the additional timing belt work was done. The commonly related item to the power seat, lock, unlock, side mirror and steering is the fuse MPX15A and/or failed electrical loads under that, I assume. But my assumption was only done just checking the wiring diagrams. The MPX15A line is supplying +B voltage directly or indirectly to every of those. Unfortunately My Celsior is currently in use by my family member and is not here. So I still can not confirm my assumption is correct or not. I can't fully guarantee it but if you are in a hurry check the fuse MPX15A which is located in the fuse/relay box behind the battery. You also may need to check electrical loads under that too.

Hi, I have a 1995 LS400, the alarm goes off every few days without provocation. I recently had the driver's side rear door actuator replaced. Don't know if this had any effect on this problem, Can I ask for your suggestions on how to fix the problem or perhaps to disable the factory alarm system.
Thanks for your time & knowledge!

Daesunglee

Thank you for your reply.

I was embarrassed.

Suddenly the power seat, door lock, and memory seat were activated yesterday.

I started it today in expectation.

It doesn't work either.

The battery was switched over.

Tomorrow I will go to the factory and inspect the fuses.

Is that necessary?

I always appreciate the answer.

Thank you so much

hello i have a 2000 LS400.
I have some problem.
If i key off, my car’s easy-access is not working.but power is is working
Memory seat button 1,2 is a fool and door unlock button is a fool.
then i lock my car but driver’s position is lock.
First my car’s driver window is not working but other door is open then my car’s driver window is working still passenger’s window is a fool.

individual window switch is working, but driver’s combination switch is not working

p.s
recently replaced battery 80A
Yesterday driver’s combination switch was working for a moment.but today is not working




ps.2
I wrote the above article after I asked my friend to translate it. I hope it makes sense.

Why do you start a new thread next to next asking the same thing?
Also you'd better change the translator. He or she needs some more brush up on writing English.
