INSPECTION

M1524047400059

CAUTION

• Never measure circuit resistance in the air bag modules 

(squib) 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 serious personal injury.

• When replacing the parts, discard the old parts after 

deploying the air bag according to the specified proce-
dure (Refer to 

P.52B-417

).

If any malfunction is found in the following inspections, replace 
the air bag module with a new one.

1. Check the harness and connector for damage and the ter-

minal for deformation.

2. Check the air bag inflator cases for dents, cracks or defor-

mation.

3. Check the air bag module for proper installation.
