and SDM plate, or it cannot be fixed securely.)
– Check connector or lead wire of SDM for scorching, melting or damage.
– Check SDM connector and terminals for tightness.
– Check if SDM sets a DTC and is judged as malfunctioning according to the diagnostic flow. • Air bag wire harness and connections
– Check for damages, deformities or poor connections.
Refer to “Inspection of Intermittent and Poor
Connections”.
– Check wire harness clamps for tightness.
– For air bag harness including in instrument panel harness replacement, refer to “Passenger Air Bag

• When placing seat belt pretensioner on workbench or other surface, be sure to lay
it with its exhaust hole (1) side facing up. It
is also prohibited to put something on seat
belt pretensioner.
Otherwise, personal injury may result.
6) Set air bag (inflator) module or seat belt pretensioner
as follows.
• For driver air bag (inflator) module
