Reset 2002 Astra-G ECM Using OPCOM 2012V 1.59

OPCOM 2012V firmware 1.59 is mainly designed for almost all Opel vehicles diagnostics, even new cars with CAN-BUS based diagnostic, such as Vectra-C, Astra-H and Zafira-B.

The following part is about how OPCOM 2012V Can OBD2 Opel reset ECM (Engine Control Module) for 2012 Astra-G. You need to set ECM back to its factory default state prior to have a replacement/resetting. Under this case, you can install it into another car.

Hook up OPCOM scan tool to your vehicle and laptop;

You can check that the vehicle is immobilizer equipped – the Immobilizer Function Programmed is grey or not;

Open up the Immobilizer;

Go to “IMMO2 Special Functions”, and you will see “Reset Engine Control Module” function is available;

Click on the button and the swap will start.

Important Note:

1. After using this function, you may not be able to start the engine.

2. Each factory default state Engine ECU has some limited running time without immobilizer (max 10 attempts to be exact). After that number, the Engine ECU will lock itself, and no more start is allowed without a fully functioning immobilizer.

3. before you swap or replace any immobilizer related component (Engine ECU, Immobilizer ECU), you have to reset them first.

The arming of the immobilizer has some delay (usually 5-10 min), so within five or ten minutes, you may be able to start the car. But after this delay expires, you won’t be able to start the engine at all, as the immobilizer will lock the vehicle. An indicator light (SVS, or MIL) will be flashing on the dash, showing an immobilizer related problem.
