AIRBAG SYSTEM, Diagnostic DTC:B1660/43

DESCRIPTION

The passenger airbag ON/OFF indicator circuit consists of the airbag sensor assembly and passenger airbag ON/OFF indicator (clock assembly).

The passenger airbag ON/OFF indicator indicates the operation condition of the instrument panel passenger airbag assembly and front seat airbag sub-assembly RH.

DTC B1660/43 is stored when a malfunction is detected in the passenger airbag ON/OFF indicator circuit.
