4 Check D squib.
PREPARATION:
(a) Turn the ignition switch to LOCK.
(b) Disconnect negative (-) terminal cable from the battery,
and wait at least for 90 seconds.
(c) Connect the steering wheel pad connector.
(d) Connect negative (-) terminal cable to the battery, and
wait at least for 2 seconds.
CHECK:
(a) Turn the ignition switch to ACC or ON, and wait at least
for 20 seconds.
(b) Clear the DTC stored in memory
(See step 5 on page DI-349).
(c) Turn the ignition switch to LOCK, and wait at least for 20
seconds.
(d) Turn the ignition switch to ACC or ON, and wait at least
for 20 seconds.
(e) Check the DTC (See page DI-349).
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
detected by the simulation method, replace all SRS components including the wire harness.

age between D+ and body ground.
OK:
Voltage: 0 V
NG Repair or replace spiral cable.
OK
6 Check harness between airbag sensor assembly and spiral cable.
CHECK:
(a) Turn the ignition switch to ON.
(b) For the connector (on the spiral cable side) between the
spiral cable and airbag sensor assembly, measure the
voltage between D+ and body ground.
OK:
Voltage: 0 V
NG Repair or replace harness between airbag sen-
sor assembly and spiral cable.
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

INSPECTION PROCEDURE
1 Prepare for inspection.
PREPARATION:
(a) Disconnect negative (-) terminal cable from the battery,
and wait at least for 90 seconds.
(b) Remove the steering wheel pad (See page SR-12).
(c) Disconnect the connector of the front passenger airbag
assembly (See page RS-28).
(d) Disconnect the connector of the side airbag assembly RH
and LH (See page RS-42 and RS-56).
(e) Disconnect the connector of the seat belt pretensioner
RH and LH (See page BO-128).
(f) Disconnect the connectors of the airbag sensor assembly
(See page RS-63 and RS-68).
(g) Disconnect the connector of the front airbag sensor RH
and LH (See page RS-73).
(h) Disconnect the connector of the side airbag sensor as-
sembly RH and LH (See page RS-78).

2 Check source voltage.
PREPARATION:
Connect negative (-) terminal cable to the battery.
CHECK:
(a) Turn ignition switch ON.
(b) Measure the voltage between body ground and each of
IG2 and ACC on the sensor and operate electric system
(defogger, wiper, headlight, heater blower, etc.).
OK:
Voltage: 10 - 14 V
NG Check harness between battery and airbag sen-
sor assembly, and check 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 side airbag assembly connectors.
(e) Connect the seat belt pretensioner connectors.
(f) Connect the airbag sensor assembly connectors.
(g) Connect the front airbag sensor connectors.
(h) Connect the side airbag sensor assembly connectors.
(i) Turn the ignition switch to ON.
CHECK:
Operate electric system (defogger, wiper, headlight, heater
blower, etc.) and check that SRS warning light goes off.
NO Check for DTCs. If a DTC is output, perform trou-
bleshooting for the DTC. If a normal code is out-
put, 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.

14. INSTALL NO.1 TIMING BELT COVER
(a) Check that the timing belt cover gaskets have cracks or
peeling, etc.
If the gasket has cracks or peeling, etc., replace it using these
steps:
Using a screwdriver and gasket scraper, remove all
the old gasket material.
Thoroughly clean all components to remove all the
loose material.
Remove the backing paper from a new gasket and
install the gasket evenly to the part of the timing belt
cover shaded black in the illustration.
NOTICE:
When joining 2 gaskets, do not leave a gap between them.
Cut off any excess gasket.
After installing the gasket, press down on it so that
the adhesive firmly sticks to the timing belt cover.
(b) Install the timing belt cover with the 4 bolts.
