Recall - Seat Occupant Sensor Calibration Update
Subject:
Airbag System - Passenger Sensing
# 07182 - (08/22/2007)
Models:
2007 Chevrolet Equinox
2007 Pontiac Torrent
Condition
General Motors has decided that a defect, which relates to motor vehicle
safety, exists in certain 2007 Chevrolet Equinox and Pontiac Torrent vehicles. In these vehicles, the right front passenger seat is built with a passenger
sensing system. When tested with a representative, unrestrained small adult, the system is required to turn the right front passenger's frontal airbag on. An
error in the seat sensor calibration can cause it to fail this test. In the event of a crash severe enough to activate the airbags, the frontal passenger airbag
may not deploy. This could increase the occupant's risk of injury.
In addition, this condition can prevent the airbag from turning off when the seat is occupied by a small child. In the event of a crash, the frontal airbag
could deploy and the child could be killed or seriously injured by the airbag.
The owner manual explains how to use the passenger sensing system. The airbag status indicator displays the status of the airbag. Whenever the front
passenger seat is occupied, the driver should always check the airbag indicator to see if the airbag is on or off. If it is not correct for the situation, the
passenger should be moved to a different seat. A child restraint installed properly in the back seat is the safest place for children.
Correction
Dealers are to reprogram the seat's electronic control unit (ECU).
Vehicles Involved
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address
information has been prepared and will be provided in GMinfoNet Recall Reports. Dealers will not have a report available if they have no involved
vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration
data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you
are urged to limit the use of this report to the follow-up necessary to complete this recall.
Parts Information
No parts are required for this recall.
Service Procedure
Some 2007 Chevrolet Equinox and 2007 Pontiac Torrent vehicles have Passenger Presence Systems (PPS) that will require a new calibration.
The Passenger Presence System (PPS) is used to monitor the weight and pattern of an occupant on the front outboard passenger seat and communicate
the status to the Sensing and Diagnostic module (SDM) whether to enable or suppress the deployment of the passenger airbag. The PPS consists of an
electronic control module (ECU), sensor mat, heated seat element (if equipped), and PASSENGER AIR BAG ON/OFF indicators.
Reprogram the electronic control module (ECU). Refer to the instructions below.
