With the reliability of VZ replacing the ecm can be a bit of a pain.
All you need is the PIM and ECM from a donor (If the engine computer isn't already stuffed, it's hit and miss sometimes).
Rip the PIM eeprom.

Hook these up and go thru the ECM and PIM resets, don't have to link them to anything to do this.
Both are clear and ready to install, If you know the security code for the original PIM (and it hasn't already been changed) hook that back up and link the blank ECM to the car.
If you have the code for vin from holden, you could rewrite the eeprom with the correct code for the next poor sucker that has to do it after resetting the ecm.
Most already know how to get the BCM code to do this.
2 more that are not a security concern, the vehicles have gone to heaven
