DTC B1161/84 Open in Curtain Shield Squib RH
Circuit
CIRCUIT DESCRIPTION
The curtain shield squib RH circuit consists of the airbag sensor assembly and the curtain shield airbag as-
sembly RH.
It causes the SRS to deploy when the SRS deployment conditions are satisfied.
For details of the function of each component, see OPERATION on page RS-3.
DTC B1161/84 is recorded when an open is detected in the curtain shield squib RH circuit.
