The airbag system checks a short between sensors in order to operate an impact sensor. Among the PAD Switch and PAD Indicator if there is a short among them, DTC code would be set.
If you strike or spin the SRSCM at the IG "ON" state, the seat-belt pretensioner, curtain-airbag or side-airbag could be unfolded and bring on danger. Handle it with care.
If there is a short between PAD Switch and PAD Indicator's circuit, this DTC would be set. For example, if there is a short between PAD Switch and PAD Indicator's circuit, this DTC would be set and recorde in the ACU. At this time, the ACU makes warning lamp turn on to let a driver know.
