INSPECTION PROCEDURE

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.

PROCEDURE


  1. CHECK POWER DOOR LOCK OPERATION


    1. When the door control switch on the 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


    1. A011BB4E01

      Bring the electrical key transmitter near the front door outside handle assembly (for driver side), 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 (for driver side), 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.

      OK
      Entry functions operate normally.
