Door Side Airbag Sensor RH Initialization Incomplete (B1693/81,B1698/82)
DESCRIPTION
The circuit for the side collision sensor LH or RH (to determine deployment of
the front seat side airbag LH or RH and curtain shield airbag LH or RH) is composed
of the center airbag sensor, rear airbag sensor LH or RH and side airbag sensor ...
