AIR BAG SYSTEM
11) Wiring Harness Connectors
If the sensing and diagnostic module (SDM) electrical connector is not attached properly, a built
in shorting bar will connect the wire from airbag warning lamp with the SDM ground wire. This
turns on the AIRBAG indicator.
To prevent deployment during servicing, additional shorting bars are located in following
locations:
Driver airbag module connector
Passenger airbag module connector
Driver and passenger side airbag module connector
SDM wiring harness connector
Contact coil connector to airbag wiring harness ·
·
·
·
·
The shorting bar is only a backup safety device. Always disable the supplemental restraints
system (SRS) before beginning any service procedure.
12) Belt Pretensioner
The belt pretensioner enables to retract the driver and the passenger seat belt webbing to
reduce any personal impact when accounted a frontal collision.

Frontal impact against a solid concrete wall at over 25 km/h or near-frontal impact
within 30 degrees from the center of the vehicle at both corners ·

Underbody impact from the road surface; impact against the curb at a very high speed;
dropping impact onto the road surface with a large angle ·
The air bag does not inflate when:
Rollover, side impact or rear impact ·
The air bag seldom inflates when:
Weak impact in which the sensor is unable to detect (under the inflation requirements)
