DTC B0111/44 Open in Side Squib (RH) Circuit
(TMC Made)
CIRCUIT DESCRIPTION
The side squib circuit consists of the airbag sensor assembly and side airbag assembly (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±2.
DTC B0111/44 is recorded when an open is detected in the side squib (RH) circuit.
