 REMOVAL AND INSTALLATION 

M1524013500523

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 air bag modules. If faulty, replace it.

•

Do not drop the air bag modules or allow contact with water, grease or oil. Replace it if a 
dent, crack, deformation or rust is detected.

•

The removed air bag module should be stored in a clean, dry place with the deployment 
surface facing up. Do not place anything on top of it.

•

Do not expose the air bag modules to temperatures over 93

°

C.

•

After deployment of an air bag, the air bag module has been replaced with a new one.

•

Wear gloves and safety glasses when handling air bags that have already deployed.

•

An undeployed air bag module should only be disposed of in accordance with the proce-
dures (Refer to

CAUTION

• Never measure the curtain air bag module cir-

cuit resistance even with the specified tester. 
Measuring the circuit resistance with a tester 
causes accidental air bag deployment due to 
current that flows or static, resulting in seri-
ous personal injury.

• When replacing the parts, discard the old 

parts after deploying the air bag according to 
the specified procedure (Refer to 

P.52B-289

).

• There must be no abnormality to the curtain 

air bag deployment section of headlining.

1. Crack, dent or deformation to inflator surface
2. Torn air bag
3. Damaged connector, deformation of terminal, 

and harness binding
