It is 2002 LS430 with 101K miles. Battery died (I have no idea) re-charged (Battery is good according to autozone) car starts and ride as normal but All lights from dashboard are on. Check VSC, triangle warning, ABS, Battery lights are on and AC not working and Turn lights are not workings. (emergency flashers are working) thanks for your time and in advance for your tips to solve this issues. Thanks

Alternator

Checked already and it is charging fine and the car is running smooth. Thanks.

Have you checked all your fuses?
Hazard and turn signals might run on a different fuse.

By any chance was the battery jumped backwards?
How did you check the alternator?
Load tested it?

jayalaba

YES Nad1370, I did check all the fuses in 4 places and everything looks fine. You are correct Hazard and turn fuses are different. Jumped backwards? you mean + - wrong? No. connected in correct + and -. Autozone did the check. First checked without running then checked while running and said, the batter is charging from alternator with correct amount of power. Thanks. Lets say the alternator is not good, how come the AC will fail? How about turn lights?

Nad1370

Well it looks like you have multiple circuits that went haywire after the battery went dead.
When you say your AC not working, is it no blower, blows but not cold and ac light is on, AC doesnt turn on, AC light flashes when pressed...etc.
You also mentioned your Batt light is on even when idling.
Have you put a meter on the battery while at idle and see what kind of voltage its putting out?

jayalaba

Nad1370, The AC is not completely working. No blowing or any lights, No turn on. Nothing at all. Yes the battery light is on when idling along with abs, check vsc off lights. I didn't check or ask the numbers when they testing the battery. I will update first thing in the morning tomorrow. They said the battery is good after charged at the store ( I gave the dead condition). I replaced and got the lights then ran to store to make sure about alternator and they tested.

Nad1370

Ok.
Without a wiring diagram, we are dead in the water.
You said you already checked all fuses, fusible links and relays.

With these multiple circuit problems, all i can think of is a junction block where these circuits meets.
I would start at the junction block where these circuits are.
Also when checking fuses, do you just pull it out and look if its not blown or actually put a test light to it and see if there is power on those fuses.
Fuse could look good but if there is no power flowing to it when it should, then thats a problem.

I didn't check with any fuse meter Brother. I pulled and made sure no black or blown then put it back. Is there any particular place or location to check where the circuits meets? So, I would take your suggestion as advice and check all the fuses with meter tomorrow.

Nad1370

Lets start with that then.
-- Re-check all your fuses that are affected with your issue with a meter/test light.
-- Key ON of course.

jayalaba

Sure and Thanks. I will update.

If your car has NAV there's a hidden service menu that will give you real time data on battery voltage both with the car running and off- The video doesn't show it but from the main menu hit DISPLAY CHECK then VEHICLE SIGNAL CHECK.
I would check this often, cold warm running off etc, as it may reveal something Autozone missed during the 10 minutes in their parking lot. The electrical system of a 430 is rather robust and the alternator not only maintains battery voltage but also provides power to all of the MANY computers and electronic components.
If the battery died once the alternator isn't doing it's job. Turn on every accessory that currently works, headlights stereo etc, and let the car run parked. Watch the battery voltage from the hidden menu as the lower idling RPM's will barely maintain proper voltage. If the battery dies again the alternator is more than likely the culprit.

UPDATE: FIXED. I bought YAE sensor for $20 in junk yard and replaced. No more VSC off, abs, Battery lights. It is piece of cake to replace. It is located under the upholder. I follow the video to remove the panels. Thanks all.
