AIR BAG MODULE AND PRE-TENSIONER SEAT BELT DISPOSAL PROCEDURES

id081000801200

Warning

• A live (undeployed) air bag module or pre-tensioner seat belt may accidentally operate (deploy) 

when it is disposed of and cause serious injury. Always refer to the “AIR BAG MODULE AND PRE-
TENSIONER SEAT BELT DEPLOYMENT PROCEDURES” and dispose of air bag modules and pre-
tensioner seat belts in a deployed condition.

• The air bag modules and the pre-tensioner seat belts are very hot immediately after they are 

deployed. You can be burned. Do not touch an air bag module and pre-tensioner seat belt for at 
least 15 min after deployment.

• Pouring water on the deployed air bag module and pre-tensioner seat belt is dangerous. The water 

will mix with the residual gases to form a gas that can make breathing difficult. Do not pour water 
on the deployed air bag module and pre-tensioner seat belt.

• The deployed air bag module or pre-tensioner seat belt may contain deposits of sodium 

hydroxide, a caustic byproduct of the gas-generated combustion. If this substance gets into your 
eyes or on your hands, it can cause irritation and itching. When handling the deployed air bag 
module and pre-tensioner seat belt, wear gloves and safety glasses.

• Due to the adoption of 2-step deployment control in both the driver and passenger-side air bag 

modules, depending on the impact force, it is possible that inflator No.2 might not operate 
(deploy). Before disposing of the air bag module, always follow the inflator deployment 
procedures and verify the complete operation (deployment) of inflators No.1 and 2.

INSPECTION OF SST (DEPLOYMENT TOOL)

id081000801000

1. Before using the SST (49 H066 002), inspect its 

operation.

Inspection Procedure

1. Follow the steps below to inspect the SST (49 H066 002).

• If not as indicated in the table, replace the SST (49 H066 002) because it has a malfunction.

Warning

• Do not use a malfunctioning SST (49 H066 002), otherwise it could cause the air bag module or 

pre-tensioner seat belt to accidentally operate (deploy).

Caution

• Because the permissible voltage for the SST (49 H066 002) is 12 V, do not connect a 24 V power 

source because it will damage the SST. Always connect only a 12 V power source.
