DTC B1162/81 SHORT IN CURTAIN SHIELD SQUIB (RH) CIRCUIT (TO GROUND)
CIRCUIT DESCRIPTION
The curtain shield squib RH circuit consists of the airbag sensor assy cent\
er and the curtain shield airbag
assy RH.
This circuit actuates the SRS to deploy when the SRS deployment conditio\
ns are fulfilled.
DTC B1162/81 is recorded when a short to ground is detected in the curtain shi\
eld squib RH circuit.
