Smart Key Diagnostic Inspection

Self-Diagnosis Using GDS: Smart key system defects can be quickly diagnosed using GDS. GDS operates the actuator quickly to monitor the input/output value and self-diagnosis. The following three functions will be a major concern in the SMART KEY system.

1. 1
   SMART KEY Device Input Problem.
2. 2
   SMART KEY Unit Problem.
3. 3
   SMART KEY Device Output Problem.
4. 4
   SMART KEY Unit Input Problem: Switch Diagnosis
5. 5
   SMART KEY Unit Problem: Communication Diagnosis
6. 6
   SMART KEY Unit Output Problem: Antenna and Switch Diagnosis

16. 16
    With the ignition switched ON, select "ACTUATOR TEST".

    

17. 17
    Place the smart key near the corresponding antenna and operate it using GDS.

    

18. 18
    If the smart key LED blinks, the smart key is normal.
19. 19
    If the Smart Key LED does not blink, check the voltage of the Smart Key battery.

28. 28
    Select "Serial Link Check".

    

29. 29
    With the ignition switched ON, select "Receiver Communication Line Check".

    

30. 30
    Check the serial communication line using the GDS.
31. 31
    If the smart key operates normally, communication of the smart key unit, external receiver and ESCL is normal.
32. 32
    If the smart key does not operate normally, check the following items.

    A.	Open circuit or no response from the external receiver communication line.

    B.	Short of the external receiver communication line to ground.

    C.	Open circuit in ESCL or no response.

    D.	Short to ground in ESCL.

33. 33
    Place the smart key in the following blind zone and check IG ON.

    

34. 34
    If the ignition is on, the antenna operates normally.
35. 35
    Check the ignition mode of the internal antenna.
36. 36
    Place the smart key in the following blind zone and activate the antenna. Make sure the smart key LED blinks.

    

37. 37
    If the smart key LED does not blink, check the antenna in the blind zone.

    

38. 38
    Connect the GDS cable to the data link connector in the driver's side lower panel.
39. 39
    After turning the ignition ON, select "KEY FOB STATUS INFO".

    

    

40. 40
    Connect the GDS cable to the data link connector in the driver's side lower panel.
41. 41
