LR3/Disco 3
The passenger air bag deactivation indicator is installed on the center switch pack of the instrument panel. When
appropriate, the indicator illuminates to advise front seat occupants that the passenger air bag is disabled. Operation of
the indicator is controlled by the RCM (restraints control module) . The RCM (restraints control module) illuminates the
indicator when:
There is a fault with the passenger air bag firing circuit(s).
The passenger air bag is deactivated with the passenger air bag deactivation switch (where fitted).
Required by passenger seat occupant monitoring (see below).
PASSENGER AIR BAG DEACTIVATION SWITCH (ALL EXCEPT NAS AND
AUSTRALIA)
The passenger air bag deactivation switch provides a method of manually disabling the passenger air bag. The switch is
installed in the front passenger end of the instrument panel and operated by the ignition key.
When the passenger air bag deactivation switch is operated, it changes a ground connection between two pins in the
connectors of the RCM (restraints control module) . When the passenger air bag deactivation switch is selected to OFF,
the RCM (restraints control module) disables the passenger air bag and, if the front passenger seat is occupied,
illuminates the passenger air bag deactivation indicator.
OCCUPANT MONITORING
Occupant monitoring provides the RCM (restraints control module) with the occupancy status of the front passenger seat.
On NAS vehicles, the RCM (restraints control module) uses the occupancy status for control of the passenger air bag
deactivation indicator.
There are two types of occupant monitoring:
In all markets except NAS, vehicles have an occupant detection system.
In NAS markets, vehicles have an occupant classification system.
