DESCRIPTION AND OPERATION
AIRBAG CONTROL MODULE (ACM)
Two different circuits supply battery voltage from
the fuse block to the Airbag Control Module (ACM),
F15 and F25. The F15 and F25 circuits are connected
to separate bus bars internal to the fuse block. Dif-
ferent circuits from the Power Distribution Center
(PDC) and ignition switch supply battery voltage to
the fuse block bus bars.
The F25 circuit supplies battery voltage to the
ACM only when the ignition switch is in the RUN
position. The F15 circuit powers the ACM when the
ignition switch is in either the START or RUN posi-
tion.
An internal bus bar in the ignition switch connects
the A1 circuit from the PDC to the A21 circuit when
the switch is either the START or RUN position. The
A21 circuit supplies battery voltage to the bus bar in
the fuse block that feeds the F15 circuit. A 30 amp
fuse in the PDC protects the A1 and A21 circuits. A
10 amp fuse in the fuse block, cavity 9, protects the
F15 circuit.
When the ignition switch is in the RUN position, it
connects the A2 circuit from the PDC to the A22 cir-
cuit. The A22 circuit supplies battery voltage to the
fuse block bus bar that feeds the F25 circuit. A 40
amp fuse in the PDC protects the A2 and A22 cir-
cuits. A 10 amp fuse in the fuse block, cavity 5, pro-
tects the F25 circuit.
Circuits D1 and D2 are connected to the CCD Bus
and the ACM. The CCD bus is used to provide com-
munications between modules and the universal data
link connector.
The ACM has a case ground and an external dedi-
cated ground, circuit Z6. The dedicated ground con-
nects to the instrument panel right center support.
AIRBAG IMPACT SENSOR
The Airbag system uses a sensor internal to the
Airbag Control Module (ACM) to detect impact. For
information regarding operation of this sensor, refer
to the appropriate group of the Service Manual.
AIRBAG SQUIB (AIRBAG IGNITER)
DRIVERS SIDE AIRBAG
Two circuits, R43 and R45, connect the ACM to the
drivers side airbag module squib (igniter) after pass-
ing through the clock spring connector. Circuit R43
from cavity 3 of the ACM 4-way connector connects
to the squib. Circuit R45 from cavity 4 of the ACM
4-way connector connects to the squib. R43 and R45
are a twisted pair of wires.
PASSENGERS SIDE AIRBAG
Two circuits, R42 and R44, connect the ACM to the
passengers side airbag module squib (igniter). Circuit
R42 from cavity 1 of the ACM 4-way connector con-
nects to the squib. Circuit R44 from cavity 2 of the
ACM 4- way connector connects to the squib. R42
and R44 are a twisted pair of wires.
Circuits R50 and R51 are connected from the ACM
to the passangers airbag. These circuits are used to
monitor the pressure switch.
AIRBAG WARNING LAMP
The Airbag Warning lamp is used to alert the oper-
ator of a problem with the Airbag system. The lamp
is illuminated when the Airbag Control Module
(ACM) grounds the R41 circuit. Refer to the appro-
priate section of the Service Manual or Diagnostic
Test Procedures Manual to diagnosis this system.
HELPFUL INFORMATION
²Check for blown fuses in the circuit that connect
to the ignition switch and those that connect to the
ACM.
²While the bus bars in the fuse block power the
ACM, they also feed additional components on sepa-
rate fuse protected circuits.
²The ACM has a case ground and an external
dedicated ground. The dedicated ground connects to
the instrument panel right center support.
