- through 10 A fuse (No. 33, located in the fuse and fusible link box).
When smart entrance control unit receives LOCK or UNLOCK signal from keyfob, ground is supplied:
- to remote keyless entry relay terminal 2
- through smart entrance control unit terminal 7, and
- to horn relay terminal 2
- through smart entrance control unit terminal 19.
Remote keyless entry relay and horn relay are now energized, and hazard warning lamp flashes and horn sounds as a reminder.
The hazard and horn reminder has C mode (horn chirp mode) and S mode (non-horn chirp mode).
