B3048

The LED has

a short circuit

or open circuit

to the power

supply

The wire harness (A3

pin) connecting to the

immobilizer indicator

(LED) has short circuited to

the battery positive.

Check whether the theft deterrent controller's 8-core plug

wire harness is touching each other.

Check whether the wire harness which connects the 8-core

plug's A3 pin and the immobilizer indicator has short

circuited to the battery positive.

B3055

Transponder

cannot

modulate

or without

transponder

No transponder inside the

key, transponder damage,

and the theft deterrent coil

damage will lead to theft

deterrent controller receiver

failure of the response

signal from the transponder.

Check whether there is transponder in the key.

Check whether the theft deterrent coil is correct as specified

in Article 1.

Replace the transponder (please refer to immobilizer system

component replacement).

B3056

No key

message is

stored in the

theft deterrent

controller

The theft deterrent controller

hasn't been matched or

has no key duplicate, thus

there is no transponder

identification code stored

inside the theft deterrent

controller

Re-learn the keys.

B3057

PIN is not

recognized

by the theft

deterrent

controller

The theft deterrent controller

is new or has been reset.

Set up the safety code and match the theft deterrent controller

again.

B3059

No request

signal from

the electrojet

controller is

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

well connected.

Check whether the wire harness connecting the A5 pin (R

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

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

component replacement). Check whether the above failures

exists. If not, the fault most likely exists in the electrojet.

B3060

Illegal key

message is

received

No transponder

identification code stored in

the theft deterrent controller.

Use the scanner to carry out the "learning keys" function.

B3061

The

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

in Article 1.

Check whether the transponder is new or not matching.

Rematch it if it is not matched;

If the transponder has been matched, make sure to check

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

(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

(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

(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

GWFLORID Maintenance Manual

192

(b) Input the PIN code and the key matching instructions with the scanner

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

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.

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.
