3 CHECK FRONT PASSENGER AIRBAG ASSY(P SQUIB)
(a) Turn the ignition switch to the LOCK position.
(b) Disconnect the negative (-) terminal cable from the bat-
tery, and wait for at least 90 seconds.
(c) Connect the connector to the front passenger airbag
assy.
(d) Connect the negative (-) terminal cable to the battery,
and wait for at least 2 seconds.
(e) Turn the ignition switch to the ON position, and wait for at
least 60 seconds.
(f) Clear the DTCs stored in memory (see page 05-1215).
(g) Turn the ignition switch to the LOCK position.
(h) Turn the ignition switch to the ON position, and wait for at
least 60 seconds.
(i) Check the DTCs (see page 05-1215).
OK:
DTC B0105/53 is not output.
HINT:
Codes other than code B0105/53 may be output at this time, but
they are not related to this check.

USE SIMULATION METHOD TO CHECK
HINT:
Before performing the simulation method, check that the airbag sensor assy center is in check mode
(see page 05-1218).
Perform the simulation method by selecting the check mode with the hand-held tester (see page
05-1218).
After selecting the check mode, perform the simulation method by wiggling each connector of the air-
bag system or driving the vehicle on a city or rough road (see page 05-1218).
