.

AIR BAG MODULE CHECK

DANGER

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, and possible serious personal injury.

WARNING

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

P.52B-254

).

1. Check the pad cover for dents, cracks or deformation.
2. Check the connectors for damage, the terminals for 

deformation, and the harness for binding.

WARNING

[SRS is a safety related item, therefore there shall be no 
attempt to repair any component or wiring harness related 
to SRS] 

3. Check the air bag inflator case 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 steering wheel. 

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

instrument panel and front deck crossmember and check fit 
and alignment.

DANGER

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, and possible serious personal injury.

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-254

).

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

deformation.

2. Check the connector for damage, the terminals for 

deformation, and the harness for binding.

CLOCK SPRING CHECK

If any malfunction is found in the following inspections, replace 
the clock spring with a new one.
1. Check the connectors and protective tube for damage, and 

the terminals for deformation.

WARNING

[SRS is a safety related item, therefore there shall be no 
attempt to repair any component or wiring harness related 
to SRS] 

2. Visually check the case for damage.

3. Check to see that there is a charge (continuity) between the 

C-306 clock spring connector terminal 1 and C-304 horn 
switch.

4.  Insert the special tool (MB991222) from behind the airbag 

module connector of the C-305 driver's side.

5.  As shown in the figure, connect the circuit tester to the 

special tool (MB991222) and check to see that there is a

SIDE IMPACT SENSOR

M1524004600317

REMOVAL AND INSTALLATION

A side impact sensor is installed behind the center pillar trim on both driver and passenger sides of the vehi-
cle.

WARNING

•

Never attempt to disassemble or repair the side impact sensor. If faulty, replace it. 

•

Do not drop or subject the side impact sensor to impact or vibration. Replace the side 
impact sensor, if dents, cracking, deformation, or rust are present. 

•

Replace the side impact sensor after the air bag has deployed. 

NOTE: The illustration above shows the side impact 
sensor (RH). The position of the side impact sensor 
(LH) is symmetrical to this.

Pre-removal Operation
• Turn the ignition key to the "LOCK" (OFF) position.
