DTC B0101/14 Open in D Squib Circuit
CIRCUIT DESCRIPTION
The D squib circuit consists of the airbag sensor assembly, spiral cable and steering wheel pad.
It causes the airbag to deploy when the airbag deployment conditions are satisfied.
For details of the function of each component, see OPERATION on page RS±2.
DTC B0101/14 is recorded when an open is detected in the D squib circuit.
