4 Does SRS warning light come on?
PREPARATION:
(a) Disconnect the negative (-) terminal cable from the bat-
tery, and wait at least for 90 seconds.
(b) Connect the airbag sensor assembly connector.
(c) Connect the negative (-) terminal cable to the battery,
and wait at least for 2 seconds.
CHECK:
(a) Turn the ignition switch to ON.
(b) Check operation of the SRS warning light.
NO Replace airbag sensor assembly.
YES
From the results of the above inspection, the malfunctioning part can now be considered normal.
To make sure of this, use simulation method to check.
