SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-154

INSTALLATION SERVICE POINTS
>>A<< PRE-INSTALLATION INSPECTION

WARNING

Dispose of air bag modules only according 
to the specified procedure (Refer to 

P.52B-162

).

1. When installing the new air bag modules, refer to 

“INSPECTION” (

P.52B-155

).

2. Connect the negative (

−) battery cable.

CAUTION

To prevent damage to M.U.T.-III, always turn the 
ignition, switch to the “LOCK” (OFF) position 
before connecting or disconnecting M.U.T.-III.
3. Connect M.U.T.-III to the diagnosis connector.
4. Turn the ignition switch to the “ON” position.
5. Check diagnosis codes using M.U.T.-III to ensure 

that the SRS operates properly.
Confirm that the diagnosis codes other than 71, 
81, 3A and 4A are not set.

DANGER

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

P.52B-5

.)

6. Turn the ignition switch to the "LOCK" (OFF) 

position. 

7. Disconnect the negative (

−) battery cable and 

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

>>B<< CURTAIN AIR BAG HARNESS 
INSTALLATION

CAUTION

• Secure the harness clip certainly and return it 

to the back side of air bag.

• Connect the connector with the inflator cer-

tainly.

>>C<< CURTAIN AIR BAG MODULE 
INSTALLATION

CAUTION

•

Take care not to contort the curtain air bag when 

installing it.

• Take care that the surrounding components 

do not trap the air bag.

• Take care that the front pillar trim clips or 

other do not trap the strap.

Hang the strap on the strap guide.

>>D<< POST-INSTALLATION 
INSPECTION

INSPECTION

M1524014900074

FRONT SEATBACK ASSEMBLY WITH 
SIDE-AIRBAG MODULE CHECK

WARNING

•

If any improper part is found during the fol-

lowing inspection, replace the front seat-
back assembly with a new one. Dispose 
of the old one according to the specified 
procedure (Refer to 

P.52B-162

).

•

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.

CURTAIN AIR BAG MODULE CHECK

WARNING

•

If any improper part is found during the fol-

lowing inspection, replace the curtain air 
bag module (squib) assembly with a new 
one. Dispose of the old one according to 
the specified procedure (Refer to 

P.52B-162

).

•

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 that the curtain air bag deployment part of 

the headlining is normal.

2. Check the inflator surface for cracks, dents or 

deformations.

3. Check the air bag for breakage.
4. Check the connector for damage, the terminal for 

deformation and the harness for binding.

SIDE IMPACT SENSOR

REMOVAL AND INSTALLATION

M1524004600771

WARNING

•

Disconnect the negative battery terminal and wait for 60 seconds or more before starting 
work. Furthermore, the disconnected battery terminal should be covered with tape to 
insulate it.

•

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

•

Do not drop or subject the side impact sensors to impact or vibration. If denting, cracking, 
deformation, or rust are discovered in the side impact sensors, replace it with a new front 
impact sensor. Discard the old one.

•

After deployment of an air bag, replace the side impact sensors with a new one.

•

Never use an ohmmeter on or near the side impact sensors, and use only the special test 
equipment described on 

P.52B-9

.

NOTE: The figure shows the side impact sensor 
(LH).

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

• Disconnect the Negative Battery Terminal.
