Just found the following error messages , i'm searching for similar messages for AF.
At least these messages confirm that pules for driving aperture should be checked by TMP19 .
"Front-curtain Run Time Out"
"Aperture Control Pulse Error"
"Irregular Pulse Cycle Detected"
"Electronically-controlled Aperture Lens, Max Aperture Reset Error"
"Electronically-controlled Aperture Lens, Aperture Control Error"
"Aperture Control Over Run Error"
"Aperture Control Under Run Error"

Schematic refer to JAA32651, I didn't found what it is. At least it is no zoom lens, so must be simular. Or ?
It has no VR.
