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:

multimeter to check the resistance between the B1 and B2
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.
check the theft deterrent controller. Adopt the substitution
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.

SRS airbag warning lamp inspection
1. When the ignition switch is set to the ON position, check if the SRS warning lamp remains on for 6-7 s.
2. If the SRS warning lamp shuts off after 6-7 s, this is normal.
3. Except for the items listed above, diagnostic inspection is still needed\
.
System diagnosis
Airbag ECU will initiate a series of diagnostic test cycles to check if the airbag system functions are ready for
use. This diagnostic test can guard against the restraint system's faulty execution and at the same time guarantee
prompt execution in a collision. If a malfunction appears, airbag ECU will store the appropriate trouble code and
light up the warning lamp to point out the malfunction, as to make maint\
enance more convenient.
Diagnostic interface
Troubleshooting
Basic processes of the malfunction diagnostic
There are two SRS-ECU malfunctions types classified by time: current malfunction and history malfunction.
The malfunction types categorized by property are: external malfunction \
and internal malfunction.
Current malfunction trouble codes and history malfunction trouble codes may exist at the same time. External
malfunction trouble codes can be eliminated with a diagnostic instrument, but the internal malfunction trouble
codes cannot be cleared unless the SRS-ECU is changed.
Caution: After installing a new SRS airbag system electronic control unit, the airbag system warning
lamp will remain on for 6-7 s when the ignition switch is set to the ON position. This indicates that
the SRS airbag is operating properly. At this point, the system does not need to be inspected and
repaired. Aside from this case however, the system should be diagnosed and repaired.

Malfunction judgment
1. Malfunction record (trouble code storage)
After the ECU performs the diagnostic test cycle in order to verify a malfunction, the SRS-ECU will store the
relevant code, the initial detection time, the final detection time, and the number of times it occurred in the
EEPROM.
The SRS-ECU can store 16 codes at most.
