CIRCUIT DESCRIPTION
The airbag sensor assy center consists of the airbag sensor, the safing sensor, the drive circuit, the diagnosis
circuit and the ignition control, etc.
If the airbag sensor assy center receives signals from the airbag sensor, it judges whether or not the SRS
should be activated.
DTC B1100/31 is recorded when a malfunction in the airbag sensor assy center i\
s detected.
