DTCB1100/31AIRBAG SENSOR ASSY CENTER MALFUNCTION
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.
DTC No.DTC Detecting ConditionTrouble Area

HINT:
When a malfunction code other than code B1100/31 is displayed at the same time, first repair the malfunction
indicated by the malfunction code other than code B1100/31.
