INSPECTION PROCEDURE
HINT:
1 CHECK STEERING PAD (DRIVER SIDE SQUIB 2ND STEP)
CAUTION: Never connect a tester to the steering pad (driver side squib 2nd step) for measurement, as this may lead to a serious injury due to airbag deployment.
NOTICE: Do not forcibly insert the SST into the terminals of the connector when connecting.
Insert the SST straight into the terminals of the connector.
