Only Wireless Control Function is Inoperative [10/2015 - ]: Procedure

  1. CHECK POWER DOOR LOCK OPERATION 
    1. Check the power door lock operation.

      Refer to OPERATION CHECK [12/2012 - ]

    Result: 

    Locked doors do not unlock 

    GO TO POWER DOOR LOCK CONTROL SYSTEM:  HOW TO PROCEED WITH TROUBLESHOOTING [12/2012 - ] 

    Result: 

    Locked doors unlock 

    See step  2

  2. CHECK KEY REMINDER WARNING SYSTEM

      Refer to OPERATION CHECK [12/2012 - ]

    Result: 

    Key reminder warning buzzer does not operates properly 

    GO TO KEY REMINDER WARNING SYSTEM:  HOW TO PROCEED WITH TROUBLESHOOTING [12/2012 - ] 

    Result: 

    Key reminder warning buzzer operates properly 

    See step  3

  3. CHECK DOOR CONTROL TRANSMITTER ASSEMBLY 
    1. When a known good registered door control transmitter assembly is used, check that the wireless functions operate properly.

      Refer to OPERATION CHECK [12/2012 - ] 

      Result

      Result Proceed to
      Wireless door lock/unlock/back door open function operates properly with a known good door control transmitter assembly. A
      Wireless door lock/unlock/back door open function does not operate. B

    Result: 

    B 

    See step  5

    Result:

  5. CHECK WAVE ENVIRONMENT 
    1. Bring the door control transmitter assembly near the door control receiver, and perform a wireless operation check.

      HINT: 

      • When the door control transmitter assembly is brought near the door control receiver, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
      • If the inspection result is that the problem only occurs in certain locations or times of day, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.

    Result: 

    Wireless functions operate properly 

    END (AFFECTED BY WAVE INTERFERENCE) 

    Result: 

    Wireless functions do not operate properly 

    See step  6
