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.

MODULE CHECK

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.

) 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"?
