DTCB0101/14OPEN IN D SQUIB CIRCUIT
CIRCUIT DESCRIPTION
The D squib circuit consists of the airbag sensor assy center, the spiral cable sub±assy and the horn button
assy.
This circuit actuates the SRS to deploy when the SRS deployment conditions a\
re fulfilled.
DTC B0101/14 is recorded when an open circuit is detected in the D squib\
circuit.

(e)Clear the stored DTCs in the memory (See page
05±1184).
(f) Turn the ignition switch to the LOCK position.
(g) Turn the ignition switch to the ON position, and wait for at least 10 seconds.
(h)Check the DTCs (See page 05±1184).
OK:
DTC B0101/14 is not output.
HINT:
Codes other than code B0101/14 may be output at this time, but
they are not related to this check.
