DESCRIPTION
The side collision sensor RH circuit consists of the airbag ECU assembly, side airbag pressure sensor RH and No. 2 side airbag sensor assembly RH.
The side airbag pressure sensor RH detects impacts to the vehicle and sends signals to the airbag ECU assembly to determine if the SRS should be deployed.
These DTCs are stored when a malfunction is detected in the side airbag pressure sensor RH or airbag ECU assembly.
