Safety Belt Pretensioners
As part of the SRS the safety belt buckles are equipped with pretensioners. The safety belt buckle pretensioners remove excess slack from the safety belt webbing. The pretensioners are activated by the restraints control module (RCM) when the module detects a crash event force exceeding a programmed limit. The safety belt buckle pretensioners are not interchangeable from vehicles built up to 03/2002 to vehicles built 03/2002 onward.
