BST Trigger Logic

Triggering of the BST requires no additional sensors. The MRS II control module will trigger the BST as follows:

FRONTAL COLLISION:  During a frontal collision that involves deployment of any front air bag, the BST will also be triggered

SIDE IMPACT:  Depending on the severity of the side impact, the BST may also be activated.

REAR IMPACT:  Detection of server rear impact will cause the MRS II to activate the seat belt tensioners and simultaneously activate the BST.
