Side Air Bag Satellite Sensor

INFOID:0000000009269113

The side air bag satellite sensors are located on the center pillar LH

and RH next to the seat belt pretensioners. The side air bag satellite

sensors send signals to the air bag diagnosis sensor unit during a

side collision. These sensors may be identified by yellow connec-

tors.

Door Satellite Sensor

INFOID:0000000009269114

The front door satellite sensors are located in the driver and passen-

ger doors. The front door satellite sensors send signals to the air bag

diagnosis sensor unit during a side collision. These sensors may be

identified by yellow connectors.

SRS Component Connectors

INFOID:0000000009269115

DIRECT CONNECT

The following SRS components use direct-connect style harness connectors.

• Driver front air bag module

• Passenger front air bag module

• LH side curtain air bag module

• RH side curtain air bag module

• Front LH seat belt pre-tensioner

• Front RH seat belt pre-tensioner

Always pull up to release locking tab prior to removing connector from SRS component.

Always push down to lock locking tab after installing connector to

SRS component. When locked, the locking tab is level with the con-

nector housing.

SLIDE DOUBLE LOCKING

• A new style slide double locking type connector is used on certain systems and components, especially

those related to airbag control systems.

• The slide double locking type connectors help prevent incomplete locking and accidental looseness or dis-

connection.

• The slide double locking type connectors are disconnected by pushing or pulling the slider. Refer to the fig-

ure below.

• The air bag deploys if the air bag diagnosis sensor unit is activated while the ignition switch is in the ON or

START position.

• The collision modes for which supplemental restraint systems are activated are different among the SRS

systems. For example, the driver air bag module, front passenger air bag module and front seat belt pre-ten-

sioners are activated in a frontal collision but not in a side collision.

OCCUPANT CLASSIFICATION SYSTEM : System Diagram

INFOID:0000000009269118

OCCUPANT CLASSIFICATION SYSTEM : System Description

INFOID:0000000009269119

The occupant classification system (OCS) identifies different size occupants, out of position occupants, and

detects if child seat is present in the front passenger seat. The OCS control unit (2) receives inputs from the

occupant classification sensors (1) (located inside the passenger seat cushion assembly). Depending on clas-

sification of the passenger, the OCS sends a signal to the air bag diagnosis sensor unit. The air bag diagnosis

sensor unit uses this signal and the seat belt buckle switch RH signal to determine deployment or non deploy-

ment of the passenger front air bag in the event of a collision. Depending on the signals received, the air bag

diagnosis sensor unit can disable the passenger front air bag completely. The OCS (weight sensors) must be

set to zero point using CONSULT after servicing the OCS system.

NOTE:

• CONSULT can be used to confirm when “zero point reset” for OCS is complete.

• Always perform zero point reset after the removal and installation of the seat or when disconnecting the

OCS control unit harness connector even if zero point reset has been completed in the past.

• If zero point reset is incomplete, the passenger air bag will be disabled and the passenger air bag off indica-

tor will be ON.

• In case of customer concern, CONSULT can be used to confirm the passenger air bag status (readiness).
