IMMOBILIZERS GM
GM's immobilization system is called IMMOBILIZER (immobilizer), and was introduced in Brazil in August 1996 with the VECTRA B
The fault warning light in the immobilizer is the same as electronic fuel injection. When you turn the ignition key, if it is flashing means problems in the immobilizer. If it is on, normal operation.
The vehicle came from the factory with two keys, however can be encoded up to 5 keys.
This encoding can only be done with the help of a tracking device, and so has no master key.

GM has two types of immobilizers
1) In the first model that VECTRA B team; OMEGA 4.1 L and 2.2 L; CORSA 98-2001; TIGRA 97 to 99, may be placed new control units used, or simply by making the timing
2 °) In the second model that equips CELTIC 2000-2001; ZAFIRA ASTRA 200-2001 and 98-2001, the plants used must be erased before receiving new programming

CODING KEY IGNITION WITH TRANSPONDER:
To key the ignition key must be kept in the hands CARD INFO. It is a card that comes with the vehicle, which contained the immobilizer code, key code and radio code and No. chassis. Now the password immobilizer hands in between with a diagnostic device in the vehicle
To key the ignition key must be kept in the hands CARD INFO. It is a card that comes with the vehicle, which contained the immobilizer code, key code and radio code and No. chassis. Now the password immobilizer hands in between with a diagnostic device in the vehicle
and following the steps determined by the device from the encoding of the keys.
It is important to remember that when you make a new key encryption, the former should also be encoded, otherwise it will not make the car run.
The new OMEGA key only accepts a schedule, and you can not reprogram them. If the client has not INFO CARD, a request may be made by the vehicle manufacturer through a dealership, or electronic resources.
Remember that the first GM vehicles with immobilizer came with key transponder just docked and that was common in the event of key loss lose transponder. Today the newest models comes with the pasted transponder.

INJECTION ELECTRONIC MODULE (ECU)
The injection module can be replaced by another new or used.
However it is necessary to do the encoding and for this the help of a device is required. Enter the immobilizer function, and key code ownership, follow the procedures provided by the diagnostic equipment.
If the control unit recognizes an abnormality in the immobilizer, a failure which can be seen either by a tracker to also making a jumper between pins A and B or 5:06 (for the VECTR B) of the existing diagnostic connector will be recorded the vehicle.
In the case of NEW ASTRA, ZAFIRA CELTA and you can only see the flaws with a tracker Faults can be: Code 143 - communication error between the center of the immobilizer and the ECU Code 144 - key code not recognized
Code 145- key code not recognized

IMMOBILIZER
is coupled with the coil / antenna and can be replaced. The central new or reset immobilizer, this virgin and accepts a unique entry code. However this code can be any number. Serious preferably the old code that has marked the INFO CARD, because that way it will be easier to memorize .
Grave first to central immobilizer then the keys and only then the central injection. In the second generation immobilizer as is the case of the NEW ASTRA, ZAFIRA Celtic and the new code should necessarily be the same as the above, because the injection core has been coded with this code.
The CORSA FAMILY immobilizer whip is the same for cars with or without this safety feature, since these models immobilizer is optional. If the vehicle come without the factory immobilizer, it will be made a jumper between pins 6 and 7 of immobilizer central whip to the central command can get the speed sensor signal. Where this information is the fault light comes on and the vehicle begins to die slowing.

EMERGENCY STARTING
At GM line, only the NEW OMEGA has emergency start in crash case the immobilizer. To make it work, follow the procedure:
Turn the ignition key without starting for a period of two (2) hours.
When the alarm fault lamp is flashing off, start the engine. This lamp is located in the on-board computer switch.
