Air Bag Control Module: Description and Operation
CIRCUIT OPERATION
Two different circuits supply battery voltage from the fuse block to the Airbag Control Module (ACM), they are F14 and F23. The F14 and F23
circuits are connected to separate bus bars internal to the fuse block. Different circuits from the Power Distribution Center (PDC) and the ignition
switch supply battery voltage to the fuse block bus bars.
The F23 circuit supplies battery voltage to the ACM only when the ignition switch is in the RUN position. The F14 circuit powers the ACM when
the ignition switch is in either the START or RUN position.
A bus bar internal to the ignition switch connects the A1 circuit from the PDC to the A21 circuit when the switch is in either the START or RUN
position. The A21 circuit supplies battery voltage to the fuse block bus bar that feeds the F14 circuit. A 40 amp fuse in the PDC, cavity 19,
protects the Al and A21 circuits. A 10 amp fuse in cavity 9 of the fuse block protects the F14 circuit.
When the ignition switch is in the RUN position, it connects the A2 circuit from the PDC to the A22 circuit. The A22 circuit supplies battery
voltage to the fuse block bus bar that feeds the F23 circuit. A 30 amp fuse in cavity 12 of the PDC protects the A2 and A22 circuits. A 10 amp
fuse in cavity 5 of the fuse block protects the F23 circuit.
The ACM has a case ground, and an external dedicated ground, circuit Z6.
