LS V8-3.9L VIN A (2003)
WARNING:
-
Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module.
This will reduce the risk of injury in the event of an accidental deployment.
-
Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
-
The safety belt pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when
handling a safety belt buckle pretensioner or safety belt retractor pretensioner. Never probe a pretensioner electrical connector. Doing so
could result in pretensioner or air bag deployment and could result in personal injury.
-
The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could
result in injury and possible violation of vehicle safety standards.
CAUTION: If replacing only the front passenger seat cushion trim cover, the occupant classification sensor must be rezeroed.
NOTE:
-
Occupant classification sensor (OCS) system components (seat cushion foam pad, bladder with pressure sensor and electronic control unit [ECU])
are calibrated to each other and are serviced as an assembly. The OCS system components are not to be installed separately. If a new OCS system,
OCS system component or seat cushion foam pad are needed, a new OCS system service kit (seat cushion foam pad, bladder with pressure sensor
and electronic control unit) must be installed as an assembly.
-
To identify between a production OCS system and a service OCS system (OCS service kit) inspect the ECU electrical connector. A production
OCS system allows the disconnect of the ECU electrical connector. A service OCS system (OCS service kit) has the ECU electrical connector
glued to the ECU, it cannot and should not be disconnected or altered.
-
When installing a new occupant classification sensor (OCS) service kit, refer to Air Bag Systems for the OCS service kit installation procedure.
1. WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing
or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or
striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood
latches.
The first row side impact sensors are located at or near the base of the B-pillars.
The second row side impact sensors (if equipped) are located at or near the base of the C-pillars.
To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect
auxiliary batteries and power supplies (if equipped).
Disconnect the battery ground cable and wait at least one minute.
2. WARNING: To reduce the risk of serious personal injury, read and follow all warnings, cautions, notes, and instructions in the
supplemental restraint system (SRS) deactivation/reactivation procedure.
Deactivate the supplemental restraint system (SRS).
3. WARNING: To reduce the risk of serious personal injury, read and follow all warnings, cautions, notes, and instructions in the seat
removal and installation procedure.
Remove the passenger seat.
