Warning Devices

The Generic Electronic Module (GEM) and Central Timer Module (CTM) control the following warnings and chimes:
^ Driver safety belt not fastened (warning lamp and repetitive chime).
^ Key-in-ignition (repetitive chime).
^ Headlamp-on warning (repetitive chime).
^ Door ajar (warning lamp and single tone).

The following four distinct chime rates are used to indicate warning:
^ Safety belt warning chime is one chime per second.
^ Key-in-ignition warning is two chimes per second.
^ Headlamp-on warning is four chimes per second.
^ Door ajar warning is a single chime.

Safety Belt Warning Chime
The safety belt warning chime warns that the safety belt is not fastened. The safety belt warning chime will sound when the driver safety belt is not fastened when the ignition switch is turned from the OFF/LOCK or ACC to the RUN or START position.

The safety belt warning chime will stop sounding when:
^ The safety belt is fastened.
^ The ignition switch is switched from the RUN or START to the OFF/LOCK or ACC position.
^ The chime has sounded for six seconds.

The safety belt warning chime inputs are:
^ Ignition switch START position (battery potential on the START [clutch depressed] input).
^ Ignition switch RUN position (battery potential on RUN and RUN/ACC inputs).
^ Driver safety belt switch (grounded when not fastened, open circuit when fastened).

Door Ajar Warning Chime
The door ajar warning chime warns that a door has become ajar. The door ajar warning chime is a single tone with the duration of one second. The chime will sound when:
^ GEM: Driver or passenger door initially becomes ajar while the ignition switch is in the RUN position.
^ CTM: Passenger door initially becomes ajar while the ignition switch is in the RUN position.

The door ajar warning chime inputs are:
^ Ignition switch RUN position (battery potential on both RUN and RUN/ACC inputs).
^ Door ajar switches (open circuit with door closed, grounded with door ajar).

Key-In-Ignition Warning Chime
The key-in-ignition chime warns that the key is still in the ignition when the driver door is ajar. The key-in-ignition warning chime will sound when:
^ GEM: Driver door is ajar, the ignition switch is in the OFF/LOCK or ACC position and the key is in the ignition.
^ CTM: Driver door is ajar, the ignition switch is in the OFF/LOCK, ACC or RUN position and the key is in the ignition.

The key-in-ignition warning chime will stop sounding when:
^ The driver door is closed.
^ The key is removed from the ignition.
^ GEM: Ignition switch is switched to the RUN position.

The key-in-ignition warning chime inputs are:
^ Ignition switch RUN position (battery potential on both RUN and RUN/ACC inputs).
^ Ignition switch ACC position (battery potential on RUN/ACC input only).
^ Key-in-ignition switch (grounded with key-in-ignition, open circuit with key-out).
^ LH door ajar switch (open circuit with door closed, grounded with door ajar).

Headlamps Warning Chime
The headlamps warning chime warns that the headlamps are on while the driver door is ajar. The headlamps warning chime will sound when all the following conditions are met:
^ The driver door is ajar.
^ The headlamp switch is in the PARK or HEAD position.
^ The ignition switch state is in the OFF/LOCK position.
^ Key-out.

The headlamps warning chime will stop sounding when any one of the conditions above are removed. The headlamps warning chime inputs are:
^ Ignition switch OFF/LOCK (open circuit on all ignition inputs).
^ Headlamp switch (battery potential when in PARK or HEAD position, open circuit when in OFF position).
^ Driver door ajar switch (open circuit with door closed, grounded with door ajar).
^ Key-in-ignition switch (grounded with key-in-ignition, open circuit with key-out).

Safety Belt Warning Lamp
The safety belt warning lamp warns that the safety belt is not fastened. The safety belt warning lamp illuminates when it is grounded and turns off when the circuit is open. The safety belt warning lamp will illuminate when the safety belt is not fastened and the ignition switch is turned from the OFF/LOCK or ACC to the RUN or START position.

The safety belt warning lamp will turn off when:
^ The safety belt is fastened.
^ The ignition switch is switched from the RUN or START to the OFF/LOCK or ACC position.
^ After the lamp is illuminated for 61 seconds.

The safety belt warning lamp inputs are:
^ Ignition switch START position (battery potential when in START).
^ Ignition switch RUN position (battery potential on both RUN and RUN/ACC inputs).
^ Driver safety belt switch (grounded when not fastened, open circuit when fastened).

Door Ajar Warning Lamp
The door ajar warning lamp warns that a door is ajar. The door ajar warning lamp illuminates when it is grounded. The door ajar warning lamp will be illuminated when any door initially becomes ajar while the ignition switch is in the RUN or START position.

The door ajar warning lamp will turn off when all doors are closed or the ignition switch is turned to the OFF/LOCK or ACC position. The door ajar warning lamp inputs are:
^ Ignition switch START position (battery potential when in START).
^ Ignition switch RUN position (battery potential on both RUN and RUN/ACC inputs).
^ Door open warning lamp switches (grounded with door ajar, open circuit with door closed).
