DTC B1141/33 SIDE AIRBAG SENSOR ASSY (LH)
MALFUNCTION
CIRCUIT DESCRIPTION
The side airbag sensor assy LH consists of the safing sensor, diagnosis circuit and lateral deceleration sen-
sor, etc.
It receives signals from the lateral deceleration sensor, judges whether or not the SRS must be activated,
and detects diagnosis system malfunction.
DTC B1141/33 is recorded when occurrence of a malfunction in the side airbag sensor assy LH is detected.
