KNEE 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-417

).

1. Check the inflator surface for cracks, dents or deformations.
2. Check the air bag for breakage.
3. Check the connector for damage, the terminal for 

deformation and the harness for binding.
