DTC B1140/32 Side and Curtain Shield Airbag Sensor
Assembly RH Malfunction
CIRCUIT DESCRIPTION
The side and curtain shield airbag sensor assembly RH 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 detects diagnosis system malfunction.
DTC B1140/32 is recorded when occurrence of a malfunction in the side and curtain shield airbag sensor
assembly RH is detected.
