Immobilizer System

Removal/Installation of Immobilizer

System

Description

System

Components

The engine immobilizer system consists of the
following three parts: the immobilizer controller,
the key with embedded transponder and the
immobilizer coil.

PEPS forwarding configuration models are
integrated in the Intelligent Key PCB board.

Transponder

Each key has a transponder, which is a passive
electronic chip. During the system operation, it
works together with the coil to complete the
encryption and authentication between the
transponder and the immobilizer controller. The
effective information transmission distance of the
transponder is 2cm-3cm. The transponder is a
passive component, without being powered by the
battery. The above figure shows the transponder in
kind and its mounting position in the key.

Notice:

Because the transponder key is a precision
component, please pay attention to the following
points in use:

1. Don’t throw or tap the key, or do other

actions to produce sudden impact on it.

2. Don’t keep the key in high temperature

condition for a long time.

3. Don’t put the key into the washer for cleaning.

4. Don’t keep the key in the magnetic or

electromagnetic environment

Immobilizer

coil

-------------------------------------------------------------------------------------------------------------------------------------------------------------

Electrical System 3D-34

The immobilizer coil, mounted on the ignition
lock cylinder, is connected with the immobilizer
controller via the harness, which undertaken the
transmission of signals and energy between the
immobilizer controller and the transponder.

Immobilizer controller (IMMO)

The immobilizer controller is a electronic
control module consisting of the
microprocessor and various semiconductor
components and is the core component of the
immobilizer system.

Electrical Schematic Diagram

Anti-theft system electrical schematics (without
PEPS)

Anti-theft system electrical schematics (with PEPS)

System Operating Principle

After the key with a transponder is inserted into the
ignition lock and it is turned from OFF to ON, the
immobilizer controller is awakened entering the
wireless authentication status; at this time, the
immobilizer controller outputs energy and data to
the transponder via the coil. The transponder that
installed in the key receives the wireless signal and
transmits the encrypted ID signal back to the
controller via the coil. The controller decodes the
signal and compares the received ID with the
internal stored ID. If they are the same, the
wireless authentication is passed. If not, the
controller ends the identification and enters the
sleep mode.

After passing the wireless identification, the
immobilizer controller and the engine ECM will

conduct the mutual encryption and authentication.
They will compare the stored PIN with the key
respectively. If they are the same, the ECM can
start the engine successfully. If different, the ECM
won’t start the engine.

Some models, burglar match with PEPS function
keys and PEPS mainly through intelligent control
module, PEPS control module and anti-theft
controller uses an internal algorithm using UMC
between HITAG2 encryption and authentication
algorithms, security controls and engine ECM is
encrypted authentication, only the smart key and
anti-theft controller (or PEPS and security
controller), two anti-theft security authentication
between the controller and the engine ECM
through after all, it allows the engine to start the
engine ECM normal.

Immobilizer Indicator Lamp

The immobilizer indicator lamp, which is
controlled by the immobilizer controller, can
display different status of the immobilizer system:

After the vehicle is electrified and the key
is located at ACC, the immobilizer
controller is still under the standby mode;
at this time, 5S cycle indicator flashes, each
cycle indicator light 250ms;

With the key turned to ON, if the
authentication between the immobilizer
controller and the key fails, 0.5s cycle
indicator flashing lights each cycle 250ms;

With the key turned to ON, if the
authentication succeeds, the indicator lamp
goes out.

Harness

Connector

The immobilizer controller is equipped with a 10-
pin connector, shown as follows:

Electrical System 3D-32

Diagnostic Procedure

If the vehicle is sent back to the maintenance center, check whether the battery voltage is between 9V-
16V. If it is, go to the next step; if not, charge the battery to the voltage of 9V-16V and then go to the
next step.

Next step

Turn the key to ON and connect with the diagnostic instrument to establish the communication with
the IMMO. If the disgnostic instrument can read out the IMMO message, go to the next step; if not,
check the connection between the diagnostic instrument and the relevant vehicle harness. Use the
diagnostic instrument to communicate with other modules to ensure whether it is normal. If it is
normal, go to the step 6; if not, contact with the diagnostic instrument supplier.

Use the diagnostic instrument to read the IMMO fault code and record it. After finished, clear the DTC

and turn the key to OFF.

Disconnect the diagnostic instrument, repeat the steps 2 and 3 and compare the recorded DTCs.
If the DTC reoccurs, go to the step 7 by referring to the DTC Analysis List“ in the Chapter 7.
If the DTC does not reoccur, go to the next step.

Restart the vehicle. If it can be normally started, go to the step 9.
If it cannot, go to the next step.

By referring to the DTC Analysis List“ in the Chapter 6, if the fault symptom is already described in
the list, go to the next step; if not, check the other components related to the vehicle starting.

Perform the thorough troubleshooting for the system; replace parts or components and conduct the
system matching, etc.

Disconnect the diagnostic instrument and restart the vehicle to check whether the system operation is
normal or not. If it is normal, go to the next step; if not, go to the step 7.

Reconnect the diagnostic instrument and clear the IMMO or ECM DTCs. End

Next step

procedure applies to the condition that the
engine ECU, the immobilizer controller and
the key are all new. If only one key requires
to be added, start from the step 13. If the key
is lost, execute the “deleting all keys”
command to delete all the former matched

necessary to duplicate a new key, add it via
the “adding a new key” command.

Electrical System 3D-34

Function Description

System function: it must be equipped with an ECU; the ECU
of a SENSOR system shall not match with left and right
SENSORs (any one of SENSORs can match with any one of
hosts).

1. Operating Conditions of Radar System
1-2 Self-inspection Function
1-2-1. In case of failure of one sensor, the buzzer sounds for
2 times; in case of failure of two or more sensors, the buzzer
sounds for 3 times.

1-2-2. In case of a normal system, the buzzer sounds for 1
time.

The system is normal.

One sensor breaks down.

Remarks: tolerance shall
be ±50 us.

Two or more sensors break

down.

2. The detection principle is as follows: when an ultrasonic
wave meets any objects, a reflected wave will be received by
the SENSOR; and then the control box can obtain the
distance based on the duration from transmitting of the
ultrasonic wave and receiving of the reflected wave (speed of
sound is 330 meters/s), in order to alert drivers to obstacles
behind.

physical characteristics, position, angle, size and texture of
objects, or a place with a complicated background rather
than abnormal system.
6. Incapable of detection or poor detection may occur in case
of the following poor places or obstacles:
6-1 Fine objects such as wire meshes or ropes;
6-2 Driving on a road fulll with grasses or a rugged road;
6-3 Texture or surface texture tending to absorb sound wave;
6-4 Detector surface with foreign matters;
6-5 Existence of ultrasonic wave noise, metallic sound and
emission sound of high pressure gas at the same frequency;
6-6  Obstacles such as acute angled reflectors and tapered
objects.

Analysis of Common Failures

When the ignition lock is at the "ON" position and
the gearlever is at the reverse gear:

a) in case of one abnormal sensor, the buzzer

sounds for two times with "BI, BI";

b) In case of two or more abnormal sensors, the

buzzer sounds for three times with "BI, BI,
BI" and the system dose not operate.

At this moment, inspect the sensors to

determine whether they are damaged or whether
connection is wrong or disconnected. In case of
any damaged components, corresponding new
components shall be used for replacement.
