The diagnostic module monitors its own internal circuits and the supplemental airbag electrical system wiring (including the impact sensors), the system wiring, the airbag system readiness light, the airbag back up power and the airbag ignitors. Front passenger sensing system The front passenger sensing system is designed to meet the regulatory requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208 and is designed to disable (will not inflate) the front passenger's frontal airbag under certain conditions. The front passenger sensing system works with sensors that are part of the front passenger's seat and safety belt. The sensors are designed to detect the presence of a properly seated occupant and determine if the front passenger's frontal airbag should be enabled (may inflate) or disabled (will not inflate). The front passenger sensing system will disable (will not inflate) the front passenger's frontal airbag if: • the front passenger seat is unoccupied, or has small/medium objects in the front seat, • the system determines that an infant is present in a rear-facing infant seat that is installed according to the manufacturer's instructions, • the system determines that a small child is present in a forward-facing child restraint that is installed according to the manufacturer's instructions, • the system determines that a small child is present in a booster seat, • a front passenger takes his/her weight off of the seat for a period of time, • a child or a small person occupies the front passenger seat. 143 2009 Sable (mgo) Owners Guide, 2nd Printing USA (fus)
