Immobilizer System
Immobilizer system composition
This vehicle's engine immobilizer system consists of a theft deterrent ECU assembly, a theft deterrent coil as-
sembly, and two theft deterrent converter assemblies. The theft deterrent coil assembly is put on the head of
ignition lock cylinder, with the other end connected to the theft deterrent ECU assembly. The two theft deterrent
converter assemblies are separately installed inside the plastic handles\
of the two keys.
1. Position diagram
All the components of immobilizer system are assembled on the overall vehicle except for the theft deterrent
converter assemblies inside the keys. They achieve communication functions via the wire harness connections.
The following figure shows the position of each component in the overall\
vehicle.
Theft deterrent controller
Ignition lock key
Theft deterrent coil
Steering column
2. Theft deterrent controller
The theft deterrent controller assembly mainly consists of a microprocessor and peripheral components. It com-
municates with the password transmitter assembly and engine ECU. The theft deterrent controller assembly
communicates with the engine ECU via the W wire, while communicating with the theft deterrent transponder
assembly via radio frequency. The theft deterrent controller connects with the scanner via the K wire. Through
the scanner, it can initiate matching, state controlling, and malfunction diagnosti\
c on the immobilizer system.
3. Theft deterrent coil
The theft deterrent coil assembly is installed on the ignition lock cylinder, the other end of wire harness
plug is connected to the theft deterrent controller assembly. The theft deterrent coil assembly can generate
an electromagnetic field to achieve communication between the theft deterrent controller assembly and the
password transmitter assembly.
4. Transponder
The theft deterrent transponder is installed inside the key handle. It has no power supply, maintains a small size,
and long use life. It acquires electric energy and transmission signals using the stimulation of the electromagnetic
field generated by the theft deterrent coil, so as to communicate with t\
he theft deterrent controller assembly.

not necessarily mean that engine start failure is due to a immobilizer system malfunction. The reasons for start-
ing engine failures are numerous, including factors like fuel, gas, fire, electricity, wires, etc. If the engine cannot
start, first check if the immobilizer system is working normally. This can be judged by looking at the flashing
theft deterrent indicator lamp which is located on the dashboard in front of the driver seat: Insert the key into the
lock cylinder and turn it to the "ON" position. If a legal key is used to start the engine, once the warning lamp is
connected to the ON end and the transponder is confirmed, the LED will remain unlit. Then when the ON end is
disconnected and the key is pulled out, the LED will shine for 0.25 s and darken for 4 s, as to act as a warning.
If an illegal key is used to start up the engine or there is something wrong with the system, the alarm indicator
lamp will shine for 0.25 s and darken for 4 s. If all is normal, then check the other parts of the engine. If abnor-
mal, first perform immobilizer system troubleshooting. A scanner can be used to judge if the immobilizer system
is working normally, but the precondition is that the scanner must be able to establish communication with the
theft deterrent controller.
1. If communication cannot be established, consider the following:
(a) Check whether the battery voltage is higher than 9 V
(b) Check whether the scanner plug is well contacted to the vehicle socket
(c) Use a multimeter to check whether the 7 pin of the OBD-II plug (diagnostic plug) is connected to the theft
deterrent controller's A7 pin
(d) Check whether the power supply of the theft deterrent controller is normal. (Use a multimeter to measure
whether the voltage of the theft deterrent controller's socket A1 pin and A2 pin is higher than 9 V)
(e) Then adopt the substitution method, which is to replace the theft deterrent controller to check if there is
anything wrong with the theft deterrent controller.
• If the failure is related to the theft deterrent controller, change it and initiate re-matching.
• If the failure has nothing to do with the theft deterrent controller, remove the electronic controller which
is connected to the alarm's K wire, such as the ABS controller, engine electrojet controller, airbag ECU
assembly, etc., as to ascertain if the present fault is caused by the wire harness connected with the theft
deterrent controller's K wire.
2. If communication can be established
Connect the scanner to the vehicle diagnostic port. Insert the key into the steering lock, and turn it to the "ON"
position, then select the scanner to check the immobilizer system's trou\
ble code.
3. Security system troubleshooting
Investigate the problem and perform troubleshooting according to the tro\
uble code on the scanner:

pins. The normal resistance is about 5-30 Ω. If the resistance
is close to zero, that means the coil has been short circuited.
If the resistance is infinite, then it means the coil's circuit is
open. Measure the resistance between pins B1 and B3, and
B2 and B3, normally they are infinite. If the resistance gains
a certain value, then it means the coil is short circuited or
leaking electricity.
If there is nothing wrong with the coil, the next step is to 4.

approach, replace it with a non-matched new theft deterrent
controller or an theft deterrent controller which has been
reset (please refer to the immobilizer system component
replacement). Insert the key into the ignition lock and turn it
to the "ON" position and read the trouble code. If there is no
9000 failure, it means the replaced controller has an internal
malfunction, and the new replaced controller must be re-
matched.

4. Security system component replacement
When a failure appears in one of the immobilizer system components, this component must be replaced. After
the replacement, perform matching on the immobilizer system again.
Only changing the coil
There is no need to match the immobilizer system again.
Only changing the key (theft deterrent transponder assembly)
(a) Get the vehicle's PIN code from the code located inside the burglar-proof classified envelope
(b) Connect the scanner with the vehicle's diagnostic connection
(c) Insert the key into the ignition lock and turn it to the "ON" position
(d) Check whether the key is legal and matched. If it is illegal or already been matched, then it cannot be
matched again, but will have to be replaced
(e) Input the PIN code with the scanner
(f) Erase the damaged lost key's information
(g) Match the new key according to the scanner's prompt
(h) If it is necessary to match another key, insert the key, and after resetting the scanner, operate according to
steps c, d, e, and g.
Caution: Make sure the key is legal and hasn't been matched before learning the key. Otherwise, the
immobilizer system won’t successfully match or the scanner will display that it has been matched but
the electrojet's validation is not available.
Only replacing the theft deterrent controller assembly
(a) Get the vehicle's PIN code from the code inside the burglar-proof classified envelope
(b) Turn off the ignition switch, and replace with an unmatched new theft deterrent controller or reset the theft
deterrent controller
(c) Insert the key into the ignition lock and turn it to the ON position
(d) Input the PIN code with the scanner
(e) Match the theft deterrent controller assembly according to the scanner prompts
(f) Because the theft deterrent controller is new, there is no VIN and original key information stored in it. It
will need the VIN inputted and must be matched with the original key, otherwise the original key will not
work.
Caution:
(a) Replace the new alarm remote controller or reset the alarm remote controller, or the alarm re-
mote controller system matching can not be completed.
(b) Select "Read EMS to alarm remote controller", not "Read alarm remote controller to EMS", or it
will make the transponder inoperable.
Only replacing the engine ECU
(a) Get the vehicle's PIN code from the code inside the burglar-proof classified envelope
(b) Turn off the ignition switch, and replace with a new non-matched or reset ECU
(c) Insert the key into the ignition lock and turn it to the ON position
(d) Input the PIN code with the scanner
(e) Match the ECU according to the prompts on the scanner, and complete the ECU and theft deterrent
controller matching.
Caution:
(a) Make sure to replace it with a new or reset ECU, otherwise the immobilizer system matching can-
not be completed.
(b) Select the menu of "Read EMS to theft deterrent controller", but not "Read theft deterrent control-
ler to EMS", or it will make the transponder inoperable.
Replacing the theft deterrent controller and EMS controller at the same\
time
If both the theft deterrent controller and EMS controller need to be changed at the same time, then the transpon-
der that has been matched must also be replaced, otherwise the immobilizer system matching cannot be com-
pleted. The immobilizer system needs to be re-matched after being replace.
Matching after sales stage
Problems caused by lost keys or immobilizer system failures requires a duplicate key, replaced parts, etc. These
problems cannot be solved without re-matching the immobilizer system's parts. During the matching, input the
correct PIN code with scanner. Specific possible problems and matching methods the maintenance station may
encounter are as follows:
1. Match an empty key:
(a) Properly connect the engine ECU and the theft deterrent controller, and then insert the key to be matched,
and switch the ignition switch to the ON position

Downloaded from www.Manualslib.com manuals search engine GWFLORID Maintenance Manual192
(b) Input the PIN code and the key matching instructions with the scanner
(c) If the PIN code is correct, after receiving the key matching instructions, transponder learning will be
complete
(d) Switch off the ignition switch
2. Check the key quantity:
Check the alarm's currently matched key quantity and matchable key quantity with the scanner .
3. Match the theft deterrent controller:
(a) Properly connect the engine ECU and the theft deterrent controller
(b) Input the PIN code and theft deterrent controller matching instructions with the scanner
(c) If the PIN code is correct, after receiving the theft deterrent controller matching instructions, matching will
be complete.
After theft deterrent controller matching is done, it needs to re-learn each key if the original key is still to be
used. If the original key will not be in use any more, then it needs to \
rematch the new key.
4. Match the engine ECU
(a) Properly connect the engine ECU and the theft deterrent controller.
(b) Input the PIN code and engine ECU matching instruction with the scanner.
(c) If the PIN code and instructions are correct, the matching process will be completed automatically.
5. PIN code scan-resisting strategy
From the matching process above, it's apparently that the PIN code is a security code for the matching process.
This code is passed to the vehicle owner in document format during the sales service. If it is lost accidentally,
the customer service staff can check the vehicle identification code stored in the theft deterrent controller with a
scanner, and then send it to the authorized staff in the factory to check the PIN code. In order to prevent someone
from illegally scanning the PIN code, it uses a forced time-delay method to prevent divulgence of information.

Caution: Please do not place anything on the auxiliary airbag, as to avoid accidents while deploying
the airbag.
Operation essentials
1. Driver side airbag and steering wheel removal
Caution: The following operations should only be performed after the battery's negative (-) terminal
has been disconnected, and after the ignition switch key has been pulled\
out for 60 s.
(a) Remove the mounting screws from the two holes under the steering wheel bottom cap, and lightly pick up
the driver side airbag module.
(b) Pull out the deployed airbag module's wire harness and the horn line, and remove the airbag module\
.
Attention: Diagnose the airbag module's circuit with an electrical measuring instruments but do not
dismantle it. Face the bottom of the removed passenger side airbag upwards and store it in a clean
and dry place.
(c) Remove the steering wheel mounting bolt on the steering column.
Caution: Due to the over-tight occlusion of the spline and column, the steering wheel and steering
column may be hard to separate, in which case make sure not to use force to remove the steering
wheel. The correct method is to tighten the screw into the column just a bit, and then pull up the
steering wheel (because the steering wheel bottom is connected to the clock spring, if force is used to
remove it, it may damage it).
2. Clock spring removal
(a) After steering wheel removal is completed, remove the combination switch hood.
(b) Pull out the dashboard wire harness connectors under the clock spring.
(c) Take off the clock spring.
Caution: Store the removed clock spring in a clean and dry place.
3. Installation notes
(a) Inspection before installation, inspection of driver side airbag module.
(b) Inspect the new airbag or clock spring before installing them.
4. Driver side airbag module inspection
Inspect each of the following items. If any faults are found, replace with a new corresponding airbag module
part. Discard the old components after they have been deployed in the pr\
oper order.
(a) Whether the cover sunken or depressed, cracked, or deformed.
(b) Whether the wire harness has broken connectors and deformed terminals.
(c) Whether the gas generator's housing is sunken or depressed, cracked, or deformed.
(d) Airbag module installation status.
Caution: The specified measuring instrument cannot measure the airbag module (tube rupture) circuit
resistance. Test the resistance with a testing instrument. There is an electric current in the tube rup-
ture which may lead to accidental deployment due to static electricity a\
nd cause serious accidents.
5. Clock spring inspection
Inspect each of the following items. If any fault is found, replace with\
a new clock spring.
