DTC B1141/33 Side Airbag Sensor Assembly (LH)
Malfunction
CIRCUIT DESCRIPTION
The side airbag sensor assembly (LH) consists of the safing sensor, diagnosis circuit and lateral deceleration
sensor, etc.
It receives signals from the lateral deceleration sensor, judges whether or not the SRS must be activated,
and diagnosis system malfunction.
DTC B1141/33 is recorded when occurrence of a malfunction in the side airbag sensor assembly (LH) is
detected.
