DTC B0111/44 OPEN IN SIDE SQUIB (RH) CIRCUIT
CIRCUIT DESCRIPTION
The side squib RH circuit consists of the airbag sensor assy center and the\
separate type front seat back
assy (side squib RH).
This circuit actuates the SRS to deploy when the SRS deployment conditio\
ns are fulfilled.
DTC B0111/44 is recorded when an open circuit is detected in the side squib RH c\
ircuit.
