The RCM (restraints control 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).
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the airbag has deployed, the airbag will not function again
and must be replaced immediately. If the airbag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
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,
The front passenger sensing system will turn off the passenger seat side
airbag if:
• the seat is empty and safety belt is unbuckled.
