DTC
B1100/31
AIRBAG SENSOR ASSY MALFUNCTION
CIRCUIT DESCRIPTION
The airbag sensor assy center consists of a airbag sensor assy center, safing sensor, drive circuit, diagnosis
circuit and ignition control, etc.
It receives signals from the airbag sensor, judges whether or not the SRS must be activated, and detects
diagnosis system malfunction.
DTC B1100/31 is recorded when occurrence of a malfunction in the airbag sensor assy center is detected.
DTC No.
