INSPECTION PROCEDURES
1 Preparation.
PREPARATION:
(a) Disconnect negative (-) terminal cable from the battery,
and wait at least 90 seconds.
(b) Remove the steering wheel pad (See SR Section).
(c) Disconnect the connector of front passenger airbag as-
sembly (See page RS-21).
(d) DIsconnect the connector of airbag sensor assembly
(See page RS-33).
CAUTION:
Store the steering wheel pad with the front surface facing
upward.
2 Check source voltage.
PREPARATION:
(a) Connect negative (-) terminal cable to the battery.
(b) Turn the ignition switch ON.
CHECK:
Measure the voltage at IG2 or ACC on sensor and operate elec-
tric system. (defogger, wiper, headlight, heater blower, etc)
OK:
Voltage: 10 - 14 V
NG Check the harness between battery and airbag
sensor assembly, and check the battery and
charging system.
OK

3 Does SRS warning light turn off ?
PREPARATION:
(a) Turn the ignition switch to LOCK.
(b) Connect the steering wheel pad connector.
(c) Connect the front passenger airbag assembly connector.
(d) Connect the airbag sensor assembly connector.
(e) Turn the ignition switch ON.
CHECK:
Operate electric system checked in (defogger, wiper, headlight,
heater blower, etc.) and check that SRS warning light goes off.
NO Check for DTCs. If a DTC is output, trouble-
shooting for the DTC. If a normal code is output,
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 the simulation method to check.
