least 60 seconds.
(e) Check the DTCs (see page DI±1147).
OK:
DTC B1625/22 is output.A
DTC B1620/21 is output.B
DTC B1620/21 and B1625/22 are not
output.C
HINT:
Codes other than DTC B1620/21 and B1625/22 may be output
at this time, but they are not related to this check.
A Replace airbag sensor assembly
(see page RS±82).
B Replace side airbag sensor assembly LH
(see page RS±92).
C
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 (see page DI±1137).
