Metro L3-061 1.0L VIN 6 TBI (1998)
Audible Warning Device: Description and Operation
Ignition Key Warning Alarm
Battery voltage is applied at all times through the DOME Fuse to the Ignition Key Warning Switch. When the ignition key is inserted into the Ignition
Cylinder, the Ignition Key Warning Switch closes and a voltage signal is provided to the Audio Alarm Module. If the LH Front Door is opened, the LH
Front Door Jamb Switch closes and provides a ground signal to the Audio Alarm Module. When these two signals are received, the Audio Alarm
Module activates the ignition key warning alarm (approximately 2 pulses per second). The alarm will continue to sound until either the ignition key is
removed from the Ignition Cylinder or the LH Front Door is closed. The alarm will stop if the Audio Alarm Module receives an ignition ON signal from
the IG-COIL Fuse when the LH Front Door is open.
