PROBLEM SYMPTOMS TABLE
HINT:
- If a problem occurs in certain locations or at certain times of day, check for the possibility of wave interference.
- When the electrical key transmitter sub-assembly is brought near a door control receiver (RF band), door outside handle assembly (LF band), indoor electrical key antenna (LF band) or any of the electrical key antennas (LF band), the possibility of wave interference decreases. By doing this, whether wave interference is causing the problem can be checked.

If multiple suspected areas are listed, the potential causes of the symptoms are listed in order of probability in the "Suspected Area" column of the table. Check each symptom by checking the suspected areas in the order they are listed. Replace parts as necessary.
