I needed to do this because I removed an ECU which had been cowboy fitted by swapping the ECU, immobilizer and key chips from another car.
I wanted to know if anyone had disused how to do this yourself on here.
YOU WILL NEED YOUR USERNAME, PASSWORD, TESTER SERIAL NUMBER AND PASSCODE.I can get the code myself from the ecu using a cheap mpps clone from eBay.

If the customer has lost the car pass with security details, then the pin code must be sought from the dealer. However, the security code can only be programmed once and cannot be erased or overwritten. If a new control unit is fitted, the new unit is not programmed with a code, and must be programmed using the TECH or AD PROGRAMMING SYSTEM. The security code consists of a 4-digit number and can be found on the car pass. The security code cannot be erased or overwritten using the TECH 1, TECH 2 or the AD PROGRAMMING SYSTEM. Car Pass The information that is stored in the control unit includes Security Code, Engine type and transponder code. Each transponder has a different code for security. Transponder (Mounted in key fob) The key fob contains a small electronic circuit (Transponder) which is powered when in close proximity to the control unit using cordless voltage power. It is not possible to change this code once programmed. If a different code is used to that on the CAR PASS, please ensure this is written down and passed to the customer for safe keeping. NOTE : If a new immobiliser ECU is fitted to the vehicle, then the code that is entered will be stored in the memory for any future programming requirements. The control unit can only be re-programmed if the necessary security code is entered, which is found on the customer vehicle information card (CAR PASS). The system uses what is called an IMO (Immobiliser Signal Code) signal to talk to the electronic engine management system, or for Diesel vehicles the Fuel Cut-off Solenoid. If there is a malfunction then the engine check light mounted in the instrument panel will flash. If the signal is incorrect the engine which is allowed to start initially is then switched OFF. If the code is recognised the immobiliser sends the signal and the ECU compares the code with what is programmed. Immobiliser Control Unit The immobilisers function is to transmit the start signal to the engine management ECU after it has read the transponder code. The system is also operated independently from the central locking system, and it’s main function is to inhibit starting. The immobiliser system is independent, and can be diagnosed separately. The first systems were fitted to Petrol vehicles and subsequently fitted to Diesel vehicles from 95½ Model Year. GENERAL OPERATION Introduction The General Motors Immobiliser is used in conjunction with the vehicle engine management electronics to immobilise the vehicle. 7ĪPPLICATIONS GENERAL MOTORS CAN PIN CODE READING PROĭIAGNOSTIC SOCKETS/PORTS OPEL/VAUXHALL/GMHOLDEN = Will read pin code on certain fixed code immobilisers.
