SEAT BELT FORCE LIMITER
DIAGNOSTIC
REQUIREMENTS
SYSTEM FAULT RECOGNITION
SYSTEM FAULT RECOVERY
32
The front seatbelt force limiter is designed to reduce
the restraining force of the seatbelt webbing to the
occupant's chest during a collision. If the collision
force reaches a certain value, the torsion bar in the
pretensioning seatbelt system deforms and allows a
small webbing to be extracted from the seat belt, thus,
reducing the restraining force on the occupant
The SRSCM shall start the self-diagnostic during the
power on. The SRSCM qualifies a fault when the fault
has been detected for the period or number of
samples listed in the DTC List.
If a fault has been qualified, the SRSCM stores the
fault codes in EEPROM and turns on the SRI.
A fault is "dequalified" when the fault has not been
detected for the period or number of samples listed in
the Fault Code List. If no other faults are active, the
SRI turns OFF. This status is called "historic fault."
The SRSCM sets active faults and historic faults as
soon as the fault condition is no longer present.
AND ERASE
The Hi-Scan Pro may erase system faults and active and
historic trouble codes. But if the cause of a current
fault is not corrected, the fault will again be recorded as
an active fault with a new "first detected" time.
Belt Pretensioner only deployment fault code is
erasable using the Hi-Scan Pro unless the indication
counter reaches its maximum reusable value of 6.
