Hatchback without VSC (from 07/2011)

SUPPLEMENTAL RESTRAINT SYSTEMS: AIRBAG SYSTEM (for Hatchback without VSC): B1660/43: Passenger Airbag ON/OFF Indicator Circuit Malfunction
B1660/43 - Passenger Airbag ON/OFF Indicator Circuit Malfunction

DESCRIPTION

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

The passenger airbag ON/OFF indicator indicates the operation condition of the front passenger airbag.

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