Review
The 10AS Anti-Theft System monitors the condition of all hinged body panels for unauthorized opening. The system also monitors attempts to enter the cabin. Depending on the market, the vehicle may be equipped with a battery-backed siren or an anti-theft siren.
The software of the active anti-theft system is installed in the anti-theft system module. The anti-theft module also controls the following functions:
- passive anti-theft system (engine immobilizer). For more information, see chapter: Anti-theft system - passive (419-01B Anti-theft system - passive, Description and function).
- central locking. For more information, see the chapter: Handles, locks, latches and entry systems (501-14 Handles, locks, latches and entry systems, Description and function).
- interior lighting. For more information, see chapter: Interior lighting (417-02 Interior lighting, Description and principle of operation).
- light alarm. For more information, see the chapter: Outdoor Lighting (417-01 Outdoor lighting, Description and principle of operation).
To activate the active anti-theft system, you must press the lock button on the remote control or insert the key into the driver's door lock. When using the remote control, the perimeter and volume protection systems are activated simultaneously. When using the key, only the perimeter security system is activated.
Anti-theft module
The anti-theft system module is located behind the instrument panel and receives continuous power from the battery through the battery electrical junction box (BJB). The control unit consists of a radio frequency receiver (RF) and antennas for receiving signals from the remote control.
Depending on the market, the module will operate at one of two frequencies. The operating frequency is indicated on the label on the module case. The table below shows the frequencies for each market.
Frequency | Markets |
433 MHz | Europe, Gulf States, South Africa |
315 MHz | North America, Southeast Asia, Japan, Australia |
In addition, the anti-theft system module contains a built-in inertial switch. In the event of a collision severe enough to trigger the inertial switch, with the ignition in position II, the anti-theft module will unlock all doors and turn on the hazard warning lights. The anti-theft module will operate in this mode for 2 minutes. To turn off the warning lights and restore normal operation of the anti-theft system module after 2 minutes, turn the ignition switch to position 0 and then back to position II.
Remote control
The remote control is used to turn the anti-theft system on and off. The remote control has buttons for locking and unlocking. The remote control housing contains a printed circuit board for transmitting radio signals and a power source.
The radio code of the remote control consists of 2 parts. The first part is a fixed code unique to this remote. The second part is a floating code that changes according to a given algorithm. The code is received by the anti-theft system module, which is able to store the data of 4 different remote controls.
If the battery power of the remote control falls below a certain level, the remote control sends an additional radio code to the anti-theft system module. The signal is sent to the instrument panel indicator, which flashes twice every 0.5 seconds, informing the driver to replace the battery in the remote control.
Siren with battery backup
Depending on the market, the vehicle may be equipped with a battery-backed siren. Siren with battery backup installed behind the headlight (left) front wing. The battery-backed siren is tamper-proof and, as the name suggests, has its own power supply. This allows it to work even when the vehicle battery is disconnected. To increase the degree of protection, all siren wires are black.
If the siren is disconnected without first deactivating it, it will turn on and work for 4 minutes 30 seconds (if not turned off before). The alarm signal during this period will consist of 30-second continuous beeps at intervals of 5 seconds.
To deactivate a battery-backed siren for later disconnection, follow these steps:
- turn the ignition switch to position II, then back to position 0,
- disconnect the vehicle battery within 17 seconds after turning off the ignition,
- Disconnect the battery backup siren.
if disconnection of the battery caused the autonomous siren to sound, it can be reset by turning the ignition switch to position II, provided that the remote control is on the same ring as the key, or in close proximity to the ignition switch.
If the activation of the autonomous siren is caused by the activation of the perimeter or volume security systems, the reset methods are as follows:
- pressing a button on the remote control;
- turning the ignition switch to position II, provided that the remote control is on the same ring as the key, or in close proximity to the ignition switch.
Alarm siren
Vehicles not equipped with a battery backup siren are equipped with an anti-theft alarm siren. The theft alarm siren is located behind the headlight of the right front fender RH. The anti-theft siren is energized by the anti-theft system module through a relay located under the driver's seat.
When the anti-theft system is triggered, the anti-theft alarm siren emits a pulsing or constant sound signal (depending on market legislation).
Intrusion detection module
The intrusion detection module monitors movements in the vehicle interior. The module is installed:
- on 90/110 station wagon models - at the top of the right RH B-pillar
- on pickups 90/110 - on the upholstery of the ceiling next to the rear-view mirror
- on 130 double cab models, on the right RH side on the headlining, above the front door.
The intrusion detection module generates ultrasonic waves. By measuring the reflected signal, the intrusion detection module first determines "image" car interior, and then calculates whether there is movement in this area.
The intrusion detection module is connected directly to the anti-theft module. When movement is detected in the passenger compartment, the intrusion detection module transmits a pulsed AC voltage signal to the anti-theft system module, activating the alarm.

The anti-theft indicator is located on the instrument panel. The indicator provides a visual indication of the status of the anti-theft system. When the anti-theft system is activated, the indicator flashes quickly (8 Hz) within 10 seconds. During this period, the anti-theft system module activates the system. After 10 seconds, the indicator starts flashing slowly (1 Hz), as a deterrent against thieves. The anti-theft indicator is activated directly by the anti-theft system module.

Work principles
Upon receiving the correct code from the remote control, the anti-theft system module will activate the perimeter and volume security systems. The anti-theft system module also activates the passive engine immobilization system.
For more information, see chapter: Anti-theft system - passive (419-01B Anti-theft system - passive, Description and function).
Once the anti-theft system is enabled, it can operate up to 3 times in any of the activation modes. Perimetric security
Perimetric security is the control of all opened panels (saloon / luggage compartment doors and hood) for unauthorized access. The anti-theft system module monitors the status of all opened panels using a wired connection system.
The driver's door switch and hood switch are connected to the anti-theft system module via separate wires. The remaining panels to be opened are connected in parallel and connected to the anti-theft system module with one cable.
All switches are open. When the panel is opened, the switch contacts close and a ground loop is created. Ground loops are created for all areas of the body except for the hood, for which a ground loop is provided through the anti-theft system module. When the anti-theft module detects a ground loop, it detects that the panel has been opened and activates the alarm.
Surround Guard
Volumetric protection controls the movement in the cabin. When the system is turned on for the first time, the anti-theft module suspends the surround arming for 15 seconds. During this period, the air waves in the cabin subside; this prevents false positives. The anti-theft system module monitors traffic in the vehicle interior using an intrusion detection module. The anti-theft module will only arm the surround if the intrusion detection module detects no vibration for 15 seconds. If motion is detected within 15 seconds, the 15 second delay period starts again at 0.
Surround protection can be deactivated in two ways:
- By locking the driver's door with the key instead of using the RF remote control.
- By locking the car with the remote control while the driver's door is open. If the driver's door is then slammed, only the perimeter security will be activated.
Visual Indicators
NOTE: Visual and audible warnings are country specific.
When the anti-theft system is activated, its module sends a command to turn on the alarm light three times. The hazard warning lights are controlled by 2 anti-theft module commands: one turns on the left LH lights, the other turns on the right RH lights. The light alarm is switched on by a signal from the anti-theft protection module corresponding to the battery voltage. The signal to turn off the lights corresponds to the voltage on "mass".
The anti-theft system module also controls the operation of the corresponding indicator on the instrument panel. At the command of the module, the indicator flashes at a frequency of 8 Hz for 10 seconds, then switches to a frequency of 1 Hz.
If the anti-theft system is triggered, its module turns on the light alarm for 30 seconds at intervals of 0.5 seconds.
Sound signals
If the anti-theft system is triggered, its module activates an audible signal. Depending on the legislation of the market, the sound signal is given by an anti-theft alarm siren, or a siren with battery backup. According to this legislation, the siren may emit a constant or pulsating sound signal.
Depending on the specification of the vehicle, the anti-theft system module powers the battery-backed siren or the anti-theft alarm siren. To activate the siren, the anti-theft system module cuts off power and creates a ground loop.
