    CHECK WAVE ENVIRONMENT


    1. A0159GVE01

      Bring the electrical key transmitter near the rear door outside handle LH, and perform a rear door LH entry lock and unlock operation check.

      Note:

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

      Tip:

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

      • If the operation check 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.

      Table 6. Result
