1. DTC B0093[09] DTC description
The rear side airbag sensor detects a side collision and converts it into electrical signals. The SRS control unit supplies power to the rear side airbag sensor. When the rear side airbag sensor detects an impact more than or equal to a predetermined level, the impact is converted into electrical signals and transmitted to the SRS control unit. The SRS control unit deploys the SRS airbag according to the electrical signals sent from the rear side airbag sensor. If the SRS control unit detects a malfunction in the power supply circuit or ground circuit of the passenger rear side airbag sensor, the DTC is set.
