Audible Warning Device: Description and Operation
Ignition key reminder alarm
The ignition key reminder alarm sounds to alert the driver that the ignition key is in the ignition key cylinder when one of the doors is opened.
When the ignition switch is at LOCK or ACC, battery positive voltage is applied to the CPU via the key in the ignition switch. When one of the
doors is opened, ground is applied to the CPU via the door switch. When the CPU receives these signals, it sounds the ignition key reminder
alarm.
Lights-on reminder alarm
The lights-on reminder alarm sounds to alert the driver that the vehicle lights are on when one of the doors is opened. When the ignition switch is
at LOCK or ACC, battery positive voltage is removed from the CPU ignition input. When the headlight switch is left in the first or second
position, battery positive voltage is applied to the CPU via the headlight switch. When the CPU receives these signals, it sounds the lights-on
reminder alarm.
