"Lights ON" warning chime
The TAIL fuse supplies battery voltage to the "lights ON" input of the electronic time and alarm control module with the light switch in PARK or HEAD. Battery voltage is sensed by the door input of the electronic time and alarm control module at all times unless any door is opened, closing the door jamb switch and grounding the circuit. If the "lights ON" input senses battery voltage and the door input senses ground, the electronic time and alarm control module will sound the warning chime continuously, indicating that the lights have been left ON.

"Fasten belts" warning chime
The seat belt switch and driver's and right front shoulder belt switches are open if the corresponding safety belts are buckled. If electronic time and alarm control module detects a ground at either terminal C220/6 (shoulder belt input) or terminal C220/7 (lap belt input),the module will sound the warning chime six (6) times and illuminate the FASTEN BELTS indicator until all belt switches are open again, indicating that all seat belts are attached properly.

"Key in ignition" warning chime
With the key in the ignition, the key in ignition switch closes and supplies battery voltage to terminal 18 (key in ignition input) of the electronic time and alarm control module. If any door is opened, and terminal 20 (door open input) of the electronic time and alarm control module is grounded, at the same time terminal 18 (key in ignition input) has battery voltage, the warning chime will sound continuously, indicating the key has been left in the ignition.

Ignition key light operation
When the key in ignition switch is open (indicating that the key is not in the ignition), and any door jamb switch is closed (indicating that a door has opened), the electronic time and alarm control module will light the ignition key light. The light will stay lit for 30 seconds or until the ignition key is turned to ACC.
