Inspection
I. The inspection for airbag module at the side of
driver could be divided into three situations:
Automobile is not impacted, automobile is impacted but
airbag does not explode, and automobile is impacted and
airbag explodes.
1. Automobile is not impacted:
a. Make malfunction diagnostic inspection,
b. Check the safety airbag assembled on steering wheel
with your eyes,
including following items mainly:
Check whether the airbag has any cut, small crack or the surface and concave slot of airbag has
obvious changed color.
2. Automobile is impacted but airbag does not explode:
a. Make malfunction diagnostic inspection,
b. Check the disassembled safety airbag with your eyes, including following items mainly:
Check whether the airbag has any cut, small crack or the surface and concave slot of airbag has
obvious changed color.
Check whether wiring harness has any cut, crack or joint has any flaw,
Check whether steering wheel has distorted,
Check whether the plug and wiring harness of helix cable has been damaged, the loudspeaker wiring
harness plug and wiring harness has been damaged or distorted,
Check whether contacting board of steering wheel loudspeaker button has been distorted (if it has
been distorted, it is necessary to change with new safety airbag module, forbid repairing it),
Interruption situation could happen between safety airbag module and steering wheel lower defend-
ing cover, and when new airbag module is assembled on steering wheel, its surrounding clearance
must be even (Assemble and disassemble of driver airbag module should accord with correct step to
work).

necting bolts at the two sides of airbag module in wheel
hub bolt holes of wheel. Adjust the fixed position of airbag
module to make the joint hang in the wheel hub hole of
wheel. Wiring harness should be tightened. The metal
surface of airbag assembly must face the downside to
prevent wiring harness from breaking for airbag
explosion, explosive force will throw airbag to air to hurt
human or surrounding things. Airbag explosion will leave
track for surrounding things, so used wheel should be
scraped.
