Note: The immobilizer can be activated if the control system ECU has not previously undergone the immobilizer activation procedure.
Warning. Activation must be performed only with the vehicle doors closed.
Sequence of execution
1. Insert the training key into the ignition switch (lock).
2. Turn on the ignition. If the system is not activated, the immobilizer indicator light will light up in the instrument panel after 6 seconds.
Note: After the immobilizer is activated, the lamp will not light.
3. Turn off the ignition. The control lamp should start flashing at a frequency of 5 times/sec. For no more than 6 sec (while the indicator light is flashing) we remove the training key from the ignition switch (lock) and insert the working key. We turn on the ignition, and the immobilizer control unit buzzer should give three beeps.
Comment.
If the sound signals do not sound and the indicator lamp stops flashing, then:
- - the time interval was exceeded (you need to repeat the system activation from the beginning);
- - the working key has already been trained with another system;
- - the anti-theft system is faulty.
4. After waiting for two more beeps, (which the system will give 6 seconds after the last signal), turn off the ignition. While the indicator light is flashing (within 6 sec) we remove the working key from the lock, insert the training key into the lock and turn on the ignition again.
5. After turning on the ignition, the immobilizer control unit buzzer should give three beeps. After waiting for two more beeps, turn off the ignition without removing the key from the lock. After 6 seconds, the buzzer should sound once and the indicator lamp should start flashing at double the speed.
Note: If the sound signal does not sound and the indicator lamp stops flashing, you must reactivate the system from the beginning. If the failure occurs again during execution, it means that the ECU was activated with a different key. To activate the immobilizer, it is necessary to replace the ECU.
6. Within 3 seconds after the last sound signal, turn on the ignition for 2-3 seconds. After turning on the ignition, the system should emit three sound signals and turn off the indicator lamp.
7. Remove the training key.
8. After waiting at least 10 seconds, insert the working key and turn on the ignition:
- a) If after 6 seconds the control lamp does not flash, we perform a test start of the engine. The engine should start;
- b) if the indicator lamp starts blinking, turn off the ignition and wait at least 10 seconds. Turn on the ignition, the indicator should not blink and the engine should start;
- c) if after turning on the ignition, after 6 seconds the control lamp lights up continuously, the learning procedure must be repeated from the beginning.
Note: If the ECU or APS control unit is faulty, to replace them you need to use new "untrained" units, and perform the immobilizer activation process with "your" training key.
