DI4L3-12
DTC B0103/12 Short in D Squib Circuit (to B+)
CIRCUIT DESCRIPTION
The D squib circuit consists of the airbag sensor assembly, spiral cable and steering wheel pad.
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 B0103/12 is recorded when a B+ short is detected in the D squib circuit.
DTC No. DTC Detecting Condition Trouble Area

H10600 W02043 H10609 DTC B0103/12 is not output.
HINT:
Codes other than code B0103/12 may be output at this time, but
they are not relevant to this check.
NG Replace steering wheel pad.
OK
From the results of the above inspection, the malfunctioning part can now be considered normal.
To make sure of this, use the simulation method to check. If the malfunctioning part can not be
detected by the simulation method, replace all SRS components including the wire harness.
