Help! M9 Auto ISO setting doesn't work

[griffin]

Help please!
I just acquired my long-wanted M9, it's mint, it's almost new! everything works beautifully, except the Auto-ISO.

I put the setting exactly the same way as on my M8, however no matter what I try, the ISO is locked at 160, even the shutter speed goes down to 1/2 or slower.
Here is what I tried so far:
M9 + Summilux 50mm 1.4 ASPH, 6 bit coded.
reset to default setting
max shutter speed: Lens depended; 1/30s, 1/60s, 1/125s (tried a lot)
Max ISO: 600, 800, 1600, 2500

however, even the shutter goes as low as 1/2 or even 2s, the ISO didn't boost up, still at 160.

also, using the iso button on the back only views the ISO is 160, can't be changed either.

Can someone please help?

thanks!!!!

I figured it out! for some reason, the ISO setting was locked at 160. Regarding what I set @ Max ISO, it won't change.

now change the ISO setting to Auto, everything works fine
