through body groundsB18andB27.
If this signal or lock signal from remote controller is received by the time control unit, the theft warning sys-
tem will arm automatically.
When arming the theft warning system, time control unit terminal

18supplies ground intermittently to ter-
minal

opening the trunk lid or back door

opening the hood

unlocking door without using the multi-remote controller

switching the ignition ON without a NATS registered key

triggering the ultra sonic sensors

smashing the back door or rear side quarter window (wagon model only).
