Inspection

Self Diagnosis With GDS
Smart key system defects can be quickly diagnosed with the GDS. GDS operates actuator quickly to monitor, input/output value and self diagnosis.
The following three features will be major problem in SMART KEY system.

1. | Problem in SMART KEY unit input.

2. | Problem in SMART KEY unit.

3. | Problem in SMART KEY unit output.

The following three diagnostic solutions will be the main solution process to a majority of concerns.

1. | SMART KEY unit Input problem : switch diagnosis

2. | SMART KEY unit problem : communication diagnosis

3. | SMART KEY unit Output problem : antenna and switch output diagnosis

Switch Diagnosis

1. | Connect the cable of GDS to the data link connector in driver side crash pad lower panel, turn the power on GDS.

2. | Select the vehicle model and then SMART KEY system.

3. | Select the "SMART KEY unit".

4. | After IG ON, select the "Current data".

5. | You can see the situation of each switch on scanner after connecting the "current data" process.

Display | Description
FL Toggle switch | ON : Push button is ON in the driver door handle.
FR Toggle switch | ON : Push button is ON in the assist door handle.
Trunk switch | ON : Trunk button is ON.
Gear P Position | ON : Shift lever is P position.
IGN 1 | ON : IGN switch is IG position.
ACC | ON : IGN switch is ACC position.
Push Knob switch | ON : Push knob switch is ON.
External Buzzer | ON : Buzzer is ON.

Communication Diagnosis With GDS (Self Diagnosis)

1. | Communication diagnosis checks that the each linked components operates normal.

2. | Connect the cable of GDS to the data link connector in driver side crash pad lower panel.

3. | After IG ON, select the "DTC".

Antenna Actuation Diagnosis

1. | Connect the cable of GDS to the data link connector in driver side crash pad lower panel.

2. | After IG ON, select the "ACTUATION TEST".

3. | Set the smart key near the related antenna and operate it with a GDS.

4. | If the LED of smart key is blinking, the smart key is normal.

5. | If the LED of smart key is not blinking, check the voltage of smart key battery.

6. | Antenna actuation

A. | INTERIOR Antenna 1

B. | INTERIOR Antenna 2

C. | Trunk antenna

D. | BUMPER/Antenna

E. | DRV_DR Antenna

F. | AST_DR Antenna

Antenna Status Check

1. | Connect the cable of GDS to the data link connector in driver side crash pad lower panel.

2. | Select the "Antenna Status Check".

3. | After IG ON, select the "Antenna Status Check".

4. | Set the smart key near the related antenna and operate it with a GDS.

5. | If the smart key runs normal , the related antenna, smart key(transmission, reception) and exterior receiver are normal.

6. | Antenna status

A. | INTERIOR Antenna 1

B. | INTERIOR Antenna 2

C. | Trunk antenna

D. | BUMPER/Antenna

E. | DRV_DR Antenna

F. | AST_DR Antenna

Serial Communication Status Check

1. | Connect the cable of GDS to the data link connector in driver side crash pad lower panel.

2. | Select the "Serial Communication Line Check".

3. | After IG ON, select the "Receiver Communication Line Check".

4. | Check the serial communication line with a GDS.

5. | If the smart key runs normal, the communication of smart key unit, exterior receiver are normal.

6. | If the smart key runs abnormal, check the following items.

A. | Disconnection or no response of the exterior receiver communication line.

B. | The exterior receiver communication line disconnection and ground connection.

Interior Antenna Actuation Check

1. | Set the smart key in the following shade area and check the IG ON.

2. | If the ignition is ON, the antenna runs normal.

3. | Check the interior antenna ignition mode.

4. | Set the smart key in the following shade area and actuate the antenna. Check the LED of smart key is blinking.

5. | If the LED of smart key is not blinking, check the antenna in shade area.

FOB Status Check

1. | Connect the cable of GDS to the data link connector in driver side crash pad lower panel.

2. | After IG ON, select the "FOB KEY STATUS INFO".

Smart Key Status Check

1. | Connect the cable of GDS to the data link connector in driver side crash pad lower panel.

2. | After IG ON, select the "SMK STATUS INFO".

PDM Status Check

1. | Connect the cable of GDS to the data link connector in driver side crash pad lower panel.

2. | After IG ON, select the "PDM STATUS INFO".

Neutralization Status Check

1. | Connect the cable of GDS to the data link connector in driver side crash pad lower panel.

2. | After IG ON, select the "Neutralization mode".
