B1622

DTC B1622/81 Lost communication with Side Airbag Sensor RH

DESCRIPTION

Detection Condition:

for DTC B1620 and B1625:
The side airbag sensor LH and RH consists of the safing sensor, the diagnostic circuit, the lateral deceleration sensor, etc.

If the center airbag sensor receives signals from the lateral deceleration sensor, it determines whether the SRS should be activated.

DTC B1620/21 or B1625/22 is recorded when a malfunction is detected in the side airbag sensor LH or RH circuit.

for DTC B1622 and B1627:
The circuit for the side collision sensor RH or LH (to determine deployment of the front seat side airbag RH or LH, rear seat side airbag RH or LH, and curtain shield airbag RH or LH) is composed of the center airbag sensor, side airbag sensor RH or LH, and rear airbag sensor RH or LH.

The side airbag sensor RH or LH, and rear airbag sensor RH or LH detect impacts to the vehicle and send signals to the center airbag sensor to determine if the airbag should be deployed.

DTC B1622 or B1627 is recorded when a malfunction is detected in the circuit for the side collision sensor RH or LH (to determine deployment of the front seat side airbag RH or LH, rear seat side airbag RH or LH, and curtain shield airbag RH or LH).

INSPECTION PROCEDURE

NOTE: After the engine switch is turned off, the HDD navigation system requires approximately 6 minutes to record various types of memory and settings. As a result, after turning the engine switch off, wait 6 minutes or more before disconnecting the cable from the negative (-) battery terminal.
