Front Door Pressure Sensor Threshold Malfunction (RH) |
DESCRIPTION
The side collision sensor RH circuit (bus 1) consists of the airbag sensor assembly, side airbag pressure sensor RH and side No. 2 airbag sensor RH.
The side airbag pressure sensor RH and side No. 2 airbag sensor RH detect impacts to the vehicle and send signals to the airbag sensor assembly to determine if the airbags and pretensioners should be deployed.
These DTCs are stored when a malfunction is detected in the side airbag pressure sensor RH.
