DTC B1180/17 Short in Driver Side Squib 2nd Step Circuit
DESCRIPTION
The driver side squib 2nd step circuit consists of the center airbag sensor assembly, the spiral cable and the steering pad.
The circuit instructs the SRS to deploy when deployment conditions are met.
DTC B1180/17 is recorded when a short circuit is detected in the driver side squib 2nd step circuit

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.
