Check the signal levels on the processor during reading according to the table

IRQ maybe = GND, but you need +9v

post a pic of cluster if i remember correctly you have to cut a strip to be a ble to read mcu

Have you connected an external 12V power to the programmer?
Check the IRQ line, maybe it is shorted to GND
