USING ANTI-THEFT SYSTEM APS-4
On cars equipped with the APS-4 car anti-theft system (immobilizer), it is possible to switch it to an active state, in which starting the engine will be possible only with a code key, and thereby provide additional protection of the car from unauthorized use by immobilizing the engine. The set of coded keys, additionally supplied to the car, contains two black keys - working and one red - training. The keys are marked “APS-4”.
First of all, you should make sure that the anti-theft system is connected and inactive. To do this, close all the car doors except the driver's door, get into the car and close the driver's door. The interior light should remain on for another 12 seconds after the driver's door is closed, and then go out smoothly. Turn on the ignition, the system status indicator LED should light up and stay lit until the ignition is on. In this case, you can proceed to the procedure for transferring the anti-theft system to the active state, i.e. carry out the so-called “coding” of the system with code keys, which then become individual for each anti-theft system. If, when the ignition is turned on, the system status indicator LED blinks at a frequency of 2 times per second, this means that the anti-theft system on your car has already been switched to an active state earlier and you should proceed to the “Disarming” section.
ATTENTION!
If, when you turn on the ignition, the system status indicator LED does not light up, but flashes at a frequency of 1 time per second for 20 seconds, this means the following:
1. There is no electrical connection between the engine control controller and the immobilizer unit. The connection in the engine control system harness should be checked.
2. The engine control controller was previously taught code keys with another immobilizer unit. The engine will not start. You should contact a service station.
If, when the ignition is turned on, the LED does not light up, but flashes at a frequency of 5 times per second for 20 seconds, this means an error in the immobilizer unit. If this blinking does not disappear the next time the ignition is turned on, you should contact a service station.
Warning: you will have to register the keys!
Read and analyze the following:
- you can activate Valet mode on the APS-4 immobilizer only using the red training key;
- You can also disable Valet mode by using the learning key rather than any other key;
- The main thing is that the “shutdown” procedure is combined with “writing user keys”;
- If the user's keys are not registered when Valet mode is disabled, the immobilizer will not recognize them!
Usually it all ends with the service mode being disabled, but they forget to register the keys. And then there is only one key left to use: the key of learning. How are you.
