B1022 OCCUPANT SENS C/U

Description

INFOID:0000000003367349

DTC B1022 [COMM FAIL] OCCUPANT SENS C/U

Suppresses the deployment of front passenger air bag when the condition of passenger seat is empty or child
and child-seat. And turns on front passenger air bag OFF indicator (Cut-off telltale) lamp when the condition of
passenger seat is child-seat and child. In case of malfunction the blinking of the air bag warning lamp reports
the malfunction to driver and by the on board self-diagnosis system or electro-diagnosis tester CONSULT-lll
can detect the cause.

OPERATION

This unit classifies occupant in passenger seat and detects electrical malfunction in Occupant Classification
System (OCS) and transmits malfunction information to air bag control unit.

STRUCTURE

It is integrated into the seat sensor mat and detects the occupants and Occupant Classification System (OCS)
control unit that classifies the occupants.

INSTALLATION

 Occupant Classification System (OCS) control unit is installed in the passenger seat cushion.
