CHECK:
(a) Turn ignition switch to ACC or ON, and wait at least for 20
seconds.
(b) Clear DTC stored in memory.
(See step 5 on page DI±626)
(c) Turn ignition switch to LOCK, and wait at least for 20 se-
conds.

(See page DI±626)
OK:
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

DTC B0105/53 Short in P Squib Circuit
CIRCUIT DESCRIPTION
The P squib circuit consists of the airbag sensor assembly and front passenger airbag assembly.
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 B0105/53 is recorded when a short is detected in the P squib circuit.
