ENTRY AND START SYSTEM(for Entry Function) Driver Side Door Entry Lock and Unlock Functions do not Operate

DESCRIPTION

When the driver door entry lock and unlock functions do not operate, one of the following may be malfunctioning: 1) power door lock control system; 2) front door outside handle assembly (for driver side electrical key antenna); or 3) certification ECU (smart key ECU assembly).

CAUTION / NOTICE / HINT

Note


  • The entry and start system (for entry function) uses a multiplex communication system (LIN communication system) and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting Click here. Troubleshoot the entry and start system (for entry function) after confirming that the communication system is functioning properly.

  • When using the intelligent tester with the engine switch off to troubleshoot: Connect the intelligent tester to the DLC3, and turn a courtesy light switch on and off at 1.5-second intervals until communication between the tester and vehicle begins

  • Check that there are no electrical key transmitters in the vehicle.

  • Before performing the inspection, check that DTC B1242 (wireless door lock control) is not output Click here.

  • When checking the entry lock operation multiple times, the lock operation may be limited to 2 consecutive operations depending on the settings. In order to perform the entry lock operation 3 or more times, an unlock operation must be performed once (any type of unlock operation is sufficient). However, only consecutive entry lock operations are limited. Using the wireless lock or other types of lock operations, it is possible to perform consecutive lock operations without this limitation.

  • Before replacing the certification ECU (smart key ECU assembly), refer to the entry and start system (for entry function) Click here.

  • After repair, confirm DTC not reoccur with performing the "DTC Output Confirmation Operation".

PROCEDURE


  1. CHECK POWER DOOR LOCK OPERATION


    1. When the door control switch on the power window regulator master switch assembly is operated, check that the doors unlock and lock according to switch operation Click here.

      OK
      Door locks operate normally.

    NG

    GO TO POWER DOOR LOCK CONTROL SYSTEM (PROCEED TO PROBLEM SYMPTOMS TABLE) Click here

    OK

  2. CHECK WAVE ENVIRONMENT

      *B for RHD
      *a Approximately 0.3 m (0.98 ft.)

      Bring the electrical key transmitter near the front door outside handle assembly, and perform a driver door entry lock and unlock operation check.

      Note

      If the key is brought within 0.2 m (0.656 ft.) of the door outside handle assembly, communication is not possible.

      Tech Tips


      • When the electrical key transmitter is brought near the front door outside handle assembly, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.

      • If the operation is normal, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.

      Note

      Perform this check with the vehicle is stopped.


      1. Connect the intelligent tester to the DLC3.

      2. Turn the engine switch on (IG).

      3. Turn the intelligent tester on.

      4. Enter the following menus: Body / Entry & Start / Key Communication Check / Overhead + Driver Side.

      5. When the electrical key transmitter is in the position shown in the illustration, check that the wireless door lock buzzer sounds.
