AIR BAG MODULE CHECK

WARNING

•

If any component damage is found during the
following inspection, replace the air bag module
with a new one. Dispose of the old one according
to the specified procedure. (Refer to

P.52B-77

.)

•

Never attempt to measure the circuit resistance of
the air bag modules (squib) even if you are using
the specified tester. If the circuit resistance is
measured with a tester, accidental air bag
deployment will result in serious personal injury.

1. Check the pad cover for dents, cracks or deformation.

2. Check the connectors for damage, the terminals for

deformation, and the harness for binds.

3. Check the air bag inflator vase for dents, cracks or

deformation.

4. Install the air bag module (driver's side) to the steering

wheel and check fit and alignment with the wheel.

5. Install the air bag module (front passenger's side) to the

instrument panel and crossmember and check fit and
alignment.

6. Install the air bag module cover (front passenger's side) to

the instrument panel to check fit and alignment.

WARNING

•

If any improper part is found during the following
inspection, replace the front seatback assembly
with a new one. Dispose of the old one according
to the specified procedure. (Refer to

P.52B-77

.)

•

Never attempt to measure the circuit resistance of
the air bag module (squib) even if you are using
the specified tester. If the circuit resistance is
measured with a tester, accidental air bag
deployment will result in serious personal injury.

1. Check the air bag module deployment section for dents or

deformation.

2. Check connector for damage, terminals for deformation, and

harness for binds.

CLOCK SPRING CHECK
If any malfunction is found in steps 1 through 4, replace the
clock spring with a new one.
1. Check the connectors and protective tube for damage, and

the terminals for deformation.

2. Visually check the case for damage.

3. Align the paint mark of special tool MB991613 connector

number 4 with the notch in clock spring connector number 2
(arrow in the illustration) to connect the connectors number
2 and 4.

4. Measure the resistance between the terminals 22 and 23 of

special tool MB991613 connector number 5.

DANGER

Wait at least 60 seconds after disconnecting the
battery cable before doing any further work. (Refer to

P.52B-15

.)

WARNING

Battery posts, terminals and related accessories
contain lead and lead compounds. WASH HANDS
AFTER HANDLING.

Disconnect the negative (

−

) battery cable from the battery and

tape the terminal to prevent accidental connection and air bag
deployment.

INSTALLATION SERVICE POINTS

>>A<< PRE-INSTALLATION INSPECTION
Check the side impact sensor for dents, breakage and bending
and measure the resistance between the terminals, even when
installing a new side impact sensor.

>>B<< SIDE IMPACT SENSOR INSTALLATION

WARNING

If the side impact sensor is not installed securely and
correctly, the side air bag may not operate normally.

Securely connect the connector.

>>C<< POST-INSTALLATION INSPECTION

1. Reconnect the negative (

−

) battery cable.

2. Turn the ignition switch to "ON" position.
3. Does the "SRS" warning light illuminate for approximately 7

seconds, and then remain off for at least 5 seconds after
turning "OFF"?

4. If yes, the SRS system is functioning properly. If no, refer to

P.52B-55
