does anyone know if this works on a 2001 Gs300 with the Pioneer system? With ASL on, I press CD (DISC) three times while holding numbers 1 & 6, followed by holding the AM button for a few seconds, and i get a "P190" on the screen, not "AUDIO". anyone else get this, did i do something wrong?

I know it's been a while but I tried this yday and got the same output P190, P360 and P440. I guess this is to diagnose faulty hardware. However, I did find this http://www.larsdennert.com/lexusis/radiodiag.pdf , hope this helps. I wish it did work and had the option to change radio settings.

this just workd on my 99 GS3... hold down 1&6 and press CD 3times... you'll see P190... wait for beeps, then press and hold AM for a few secs... AUDIO, then proceed w/ L, R, W, P1, P2, & L respectively... I, like the original poster preferred everything set to "0" or "flat"
good luck
good luck

Doesn't work on Australian 1995 LS400?
Hi, I know this is an old thread but I tried it on my 1995 Australian delivered RHD LS400 and couldn't get it to work.
I have the "Lexus Premium Sound System" which I believe is the Pioneer system.
LexGS3 confirmed it worked for non nav systems and GRAND_LS_4 confirmed it worked for LS400.
I followed LexGS3's instructions for non nav but fell at the first hurdle.
I didn't see 1-190 displayed as described by GRAND_LS_4 nor did I see AUDIO displayed.
What am I doing wrong?
Does the stereo need to be in a certain state before starting? I tried it with the stereo off, playing CD or playing radio and in each case the CD, AM, 1 and 6 buttons did what they would normally do.
I don't think this would make any difference but I have an FM Modulator installed. It was turned off throughout my testing.
I don't want to blow my doors off but I'm keen to experiment with the settings.
Any suggestions from the audio gurus??
btw I have some of the cool "unused" features described by girvan in his original post.
rear seat audio controls - volume and channel only
adjustable antenna height.- the antenna goes up or down a little bit when you switch between AM and FM

Did some searching and couldn't find any updated info to put here.
Has anyone found a way to get into the audio mode on an 01+ GS300 NON NAV Pioneer Premium system?
Holding down 1+6 and pressing DISC 3 times will get you into the diag mode where it shows the 3 P-codes. Holding AM does not change into audio mode. I played around with a few other buttons and combinations and could not figure it out. Would this be something that Lexus would've taken out or changed for some reason?
