Belt TENSIONER System

At the onset of an impact event, each tensioner uses a pyrotechnic device which is triggered simultaneously with the airbags to rapidly retract the seat belts. With the slack removed, the occupant's forward motion in an impact will be reduced as will the likelihood of contacting interior components.

The ORC monitors the seat belt tensioner circuit and reports active and stored Diagnostic Trouble Codes (DTC's) if any problem is found.

Once a vehicle has been in an accident, the tensioner will have a Gravel/Grinding  sound to it after the tensioner has been put into use. This must be replaced along with any deployed airbags and broken or damaged parts.
