Default Automatic Sound Levelizer (ASL) button disappeared! And Nav disc Q.

I need your advice:

1. Three days ago, I started my 2002 LS430 and turned on the CD. No sound. So I tried FM and AM, still no sound. Then I noticed that the ASL button had disappeared. I also noticed that the green/blue indicator in the bass/mid/treble columns had also disappeared.

Is there something I can do myself to retrieve these? or do i have to have a Lexus dealer fix it?

I didn't realize that driving a car without a radio would be this boring!

2. Another question, so if I have this disc, which version do i have, GEN 4?

To upgrade the NAV, is 7.1 the latest version that will still allow me to override?

What is the latest GEN today that is compatible with 2002 LS430?

Hi

Try the diagnostics menu and see what faults come up... (the following is for UK spec but I think they are very similar)

To access the Diagnostic Menu on the touch screen do the following.

1. Gear selector in park.
2. Handbrake on.
3. Ignition to ACC, (or start the engine if you want to do a speed check etc) wait for navi screen to power up, click "I Agree" (or buy the Vias Ipod or dvd lead and it does it for you)
4. Press and HOLD the OPTION button and AT THE SAME TIME...
5. Turn headlights from off to sidelights five times i.e. off/side/off/side/off.
6. To exit the menu, turn off the ignition, car will then behave as normal.

You will then get this screen displayed, it shows if there are any faults stored in the ECU, mine below I presume means there are no faults...

Click the image to open in full size.

If you press Menu you will go to this screen

Click the image to open in full size.

Follow your way through the options and you get more screens,

This one shows satellites locked onto, and location etc

Click the image to open in full size.

There is one to test all the buttons (I'm pressing the AUDIO button here in case you didn't guess!!)

Click the image to open in full size.

This one shows battery, speed, ignition, lights and parking brake.

Click the image to open in full size.

These next two check colours

These next two allow you to test the touch screen, I have touched the first 5 bars on each one (sorry the second is a bit out of focus)

Click the image to open in full size.

Vehicle signal and sensor test. If you start the engine instead of just switching the ignition on you can drive away and check your speed via the sat nav in MPH or KPH

Click the image to open in full size.

I don't think there is anything you can mess up in looking at this but please do it at your own risk, I have played with mine a few times now with no ill effects.

This is for the 2001-2003 LS430. The later cars will be a bit different but I think the access method is the same

I don't know what any of the fault codes would be but maybe a Google of them would help....

Good Luck

Pete.

Nice Hayland

I knew about the diagnostic screen by was too afraid to menu down into it as I may mess something up. This is the first time I see what it looks like with your images

Haylands, thank you so much for the reply. This is what I love about this car and this forum. Great car + great help goes a long way.

I'll try and let you know what happens.

Just wonder how people get a hold of these sequences to access these hidden menus.

Now that I know how to access these hidden screens, I'll be accessing them even when there's nothing wrong. .. why? .. because I can.

I think 4 in that pic represents the version of the disc, not the generation of the navi system. Your '02 has a gen3 (discs are labeled gen2/3), so you can still upgrade to 7.1 map disc and have the override available.

Lexusthai,
My audio is doing the same thing yours was doing although mine works when it's cold (mostly) and the sound will come on occasionally when it has been on for 5-30 minutes, with the disappearing buttons and options on the NAV audio screen. Did it end up being your amp that was the issue or something else. I'm trying to fix this because like you said no tunes makes it boring. All the audio issues I can find posts for indicate amp issues but none reference the missing buttons. Please let us know what you did to fix it. Thanks
