DESCRIPTION
The front collision sensor circuit (front airbag sensor RH circuit and front airbag sensor LH circuit) is composed of the center airbag sensor assembly, front airbag sensor RH and front airbag sensor LH.
The front airbag sensor RH or front airbag sensor LH detect impacts to the vehicle and send signals to the center airbag sensor assembly to determine if the airbag should be deployed.
DTC B161A/8A is stored when a malfunction is detected in the front collision sensor circuit (front airbag sensor RH circuit and front airbag sensor LH circuit).

CHECK DTC |
(a) Turn the ignition switch to ON, and wait for at least 60 seconds.
(b) Turn the ignition switch off.
HINT:
If a communication error occurs, DTCs for both LH and RH sides will be stored simultaneously. To identify the malfunctioning area, turn the ignition switch off and then to ON again.
(c) Turn the ignition switch to ON, and wait for at least 60 seconds.
(d) Check for DTCs (See page ).
