When the electrical key transmitter is brought near the indoor electrical key antenna, 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 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.
OK:
Engine can be started.
