received
The theft deterrent
controller doesn't receive
the communication request
signal from the electrojet
controller.
Check whether the theft deterrent controller's 8-core plug is 1.
well connected.
Check whether the wire harness connecting the A5 pin (R 2.
wire) of the 8-core plug and electrojet is well connected, is
not short circuited, and is not poorly connected.
Replace the alarm (please refer to immobilizer system 3.
component replacement). Check whether the above failures
exists. If they do not, the fault most likely exists in the alarm.
Replace the electrojet (please refer to immobilizer system 4.
component replacement). Check whether the above failures
exists. If not, the fault most likely exists in the electrojet.
B3060Illegal key
message is
received
No transponder
identification code stored in
the theft deterrent controller.
Use the scanner to carry out the "learning keys" function.
B3061The
communication
with the key is
interrupted
The transponder
can not establish
communication with the
theft deterrent controller,
the communication
is interrupted, or the
communicating data is
incorrect. The electrojet
key is not identical to the
transponder's.
Check whether the theft deterrent coil is correct as specified 1.
in Article 1.
Check whether the transponder is new or not matching. 2.
Rematch it if it is not matched;
If the transponder has been matched, make sure to check 3.
whether the transponder has been changed, or the electrojet
changed or reset
• If the transponder has been changed, then it cannot be used
again, and must be replaced with a new one and then re-
matched
• If the transponder hasn't been changed and only the
electrojet has been reset, then it only needs to matched again.
• If the transponder has not been changed but the electrojet
has been changed, make sure the replacing electrojet
is new or has been reset. If the substituted electrojet is
matched but not yet reset, then it must be replaced with a
new or reset one and then 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

(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.
