AIRBAG SYSTEM, Diagnostic DTC:B1620, B1625

DTC Code DTC Name
B1620 Side Airbag Sensor RH Circuit Malfunction
B1625 Front Passenger Side - Side Airbag Sensor

DESCRIPTION

The configuration of the side airbag sensor LH is the same as that of the RH.

When the center airbag sensor assembly receives signals from the frontal deceleration sensor, it determines whether or not the SRS should be activated.

DTC B1620 is set when a malfunction is detected in the driver's side side airbag sensor circuit.

DTC B1625 is set when a malfunction is detected in the passenger's side side airbag sensor circuit.

DTC No. DTC Detecting Conditions Trouble Areas
