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.
SST 09843-18060
OK: DTC B1181/18 is not output. HINT: Codes other than DTC B1181/18 may be output at this time, but they are not related to this check.
Go to step 2
REPLACE STEERING PAD
2 CHECK DRIVER SIDE SQUIB 2ND STEP CIRCUIT
