The Telltale Lamp indicates the Passenger Airbag(PAB) enable disable status based on occupant status of passenger
seat. If the passenger seat is occupied with child (or child seat), the Passenger Airbag is disabled and the Telltale
Lamp is turned ON to inform the driver that the PAB is disabled.
As soon as operating voltage is applied to the SRSCM ignition input, the SRSCM activates telltale lamp prove out.
OCS will send an indeterminate status to the SRSCM as a default setting for passenger airbag deployment during the
prove out period. After crash if OCS gets reset and sends the indeterminate status, the telltale lamp will be ON as long
as the occupant status is in the indeterminate status. Occupant status information and telltale ststus are as below
table.

Description
The supplemental restraint system (SRS) is designed to supplement the seat belt to help reduce the risk or severity of
injury to the driver and passenger by activating and deploying the driver, passenger, side airbag and belt pretensioner
in certain frontal or side collisions.
The SRS (Airbag) consists of : a driver side airbag module located in the center of the steering wheel, which contains
the folded cushion and an inflator unit ; a passenger side airbag module located in the passenger side crash pad
containsthe folded cushion assembled with inflator unit ; side airbag modules located in the driver and passenger seat
contain the folded cushion and an inflator unit ; curtain airbag modules located inside of the headliner which contains
folded cushions and inflator units. The Passenger Occupant classification System (OCS) utilizes bladder placed
between the passenger seat cushion and suspension to measure the occupant’s loading force on the vehicle seat. Seat
Track Position Sensor (STPS) located in driver and passenger seat interfaces with SRSCM and will help in determining
whether to suppress either stage of a multistage airbag system. SRSCM is located under the center console. The
impact sensing function of the SRSCM is carried out by electronic accelerometer that continuously measure the
vehicle's acceleration and delivers a corresponding signal through amplifying and filtering circuitry to the
microprocessor.
