1. Disconnect the wire from the terminal «minus» battery.
2. Remove the instrument panel trim (see «Disassembly and assembly of the instrument panel»).
3. Remove the two screws securing the immobilizer control unit...
4.... remove the immobilizer unit from the installation site...
5.... disconnect the wiring harness connector from the terminals of the immobilizer control unit and remove the unit from the car. 6. Install the immobilizer control unit on the vehicle in the reverse order of removal. After replacing a faulty immobilizer with a new one, it is necessary to carry out the system learning procedure (see «Learning immobilizer keys»). To do this, use the learning key from the faulty immobilizer.
The APS-6 immobilizer allows the engine to be started without a learning procedure. Such an engine start can only be carried out with the learning key that was previously used when activating the anti-theft function of the engine control unit installed on the vehicle.
Start the engine as follows:
- close all doors;
- turn on the ignition with the learning key, but do not start the engine;
- turn off the ignition (the immobilizer indicator lamp should start flashing rapidly);
- no later than 6 s after switching off the ignition (while the lamp is flashing) turn the ignition back on with the learning key and start the engine.
