Operation CHARM: Car repair manuals for everyone.

Chime Warning

There are six audible warning chimes and four warning lights that the GEM controls. The GEM performs a prove out on all GEM controlled warning light miniature bulbs (except the seat belt and door ajar) by turning on the miniature bulb for two seconds after the ignition switch is turned to RUN from START. The warning chimes and lamps are described below.

Tone Request
A single tone will be provided each time a ground signal is received from the message center. A one-second tone will sound for warning indications from the message center. A tone will sound for each message center button depressed.

Headlamp On Warning
A chime sounds when the exterior lamps are on (parking, license plate, and headlamps and all of the following conditions are met:
^ Ignition switch in the OFF position.
^ There is no key in the ignition switch.
^ The driver front door is ajar (or open).

Door Ajar Warning
When at least one door is ajar and the key is in the RUN position, the door ajar cluster lamp is activated and remains on until all doors are closed. A warning tone will sound once any time the key is in the ignition switch and any door is open. The GEM's flexibility allows customizing of different warnings; for example, a steady tone for a driver door ajar.

Driver Seat Belt Warning
If the driver seat belt is unbuckled when the ignition switch is moved from START to RUN, a chime sounds for 6 seconds (or until the driver seat belt is buckled) and a warning light is turned on for 61 seconds (or until the driver seat belt is buckled).

Key In Ignition Warning
Any time the key is in the ignition switch in the OFF or ACCY position and the driver door is open, the module sounds a chime (120 chimes per minute) until either the key is removed from the ignition or the driver door is closed.
