Rear Defogger/Mirror Defogger

General Description

The system consists of the rear defogger and mirror
defogger switch, the rear defogger & mirror defogger
relay, the rear defogger & mirror defogger and the
Powertrain Control Module (PCM).
When the rear defogger and mirror defogger switch is
turned on with the starter switch on, the rear defogger and
mirror defogger relay is activated and the battery voltage
is applied to the rear defogger and mirror defogger.
The PCM is provided with the timer. When the operation
time of the timer elapses which has been set in advance,
the rear defogger and mirror defogger relay is
automatically deactivated and the rear defogger and
mirror defogger is turned off.
