if you have problem with reading release(lift) reset pin. If still problem, try to release another pin like TDO, RDI, PD4, PD3, ...
In the past I had the same problem and I tried to release some pins and after I had success!

good luck

Use upa or carprog etc.. lift reset pin and IRQ pin than read it.

The easiest way is to desolder mcu, put in adapter and read.

Friend
Only lift RESET pin and IRQ pin than read it easly

[aandroma]

When you desolder mcu you have to connect a xctall on osc1 and osc2 pin otherwise you never read mcu

Remove ecu from board.
Use adapter hc05.
Xprog MCU 68hc05b32.

You no need desolder mcu. Only lift reset and irq pin than read it. İt is very simple and easy
