Can't read VIN

Please forgive me if this is a re-post - browser crashed posting

I have built a stand-alone scanner, which works great. I can read
values, read DTCs, clear DTCs etc but one request won't work...

When I send a mode $09 PID $02 (Read VIN) I get no reply at all.
The values I'm sending (after connecting to 0x33) are :-

$68,$6a,$F1,$09,$02,$ce
But I get no reply.

However if I send
$68,$6a,$F1,$01,$0d,$d1 - get vehcile speed, this works fine.

Any ideas anyone?
