8B - 2 CHIME/BUZZER
CHIME/BUZZER (Continued)
LOW WASH INDICATOR
The Front Control Module (FCM) monitors the
washer reservoir. When the fluid is low the FCM
transmits a J1850 message over the bus. The instru-
ment cluster will chime and illuminate the LOW
WASH indicator. The indicator will remain on until
the fluid level is corrected.
AIR BAG
The Instrument Cluster monitors air bag system
via the J1850 bus communications from the air bag
module. The air bag module will transmit a message
once per second, over the J1850 bus, as to whether
the warning indicator should be on or off. The warn-
ing indicator indicates a part of the air bag system is
inoperative and needs to be serviced. It does not
indicate that the air bag system will not deploy. If
the instrument cluster does not receive a message
from the air bag module for 3 consecutive seconds,
the Instrument will illuminate the warning indicator.
The air bag module transmits a J1850 message
requesting the instrument cluster to perform a bulb
check each time the ignition is turned to the on posi-
tion
