Safety airbag system
T-52
Check of safety airbag module
The safety airbag module checked with an
ohmmeter may cause the safety airbag to release and
result in serious personnel injury. Hence, do not
check the safety airbag module by use of an
ohmmeter. The faults of safety airbag system shall
be detected with the On Board Diagnostics (OBD).
Operation of safety airbag module
When handling the safety airbag module not yet
released under working state, it may accidentally
release and result in serious personnel injury. When
carrying the safety airbag module not yet released
under working state, keep the front face outward, so
as to prevent the accidental release of airbag and
reduce the possibility of injury.
It is very dangerous to make the safety airbag
module not yet released face down under working
state. The release of safety airbag module may result
in serious personnel injury. The front face shall be
set upward, which will reduce the action scope of
module in case of accidental release of airbag.
Operation of lateral safety airbag module
When the lateral safety airbag module released due
to a collision, the internal padding frame of seat
backrest etc, may be damaged. If the seat backrest is
repeatedly used and the lateral safety airbag module
is unable to normally release, a severe accident may
have occurred, thus, when the lateral safety airbag
module releases, the lateral safety airbag module
and the padding frame of seat backrest shall be
replaced by new ones. After the maintenance,
confirm that the seat is correctly installed and fixed
by use of proper harness.
Operation of SAS unit
In case, where the ignition switch is not turn off, the
disconnection of SAS unit connector or the removal
of SAS unit may release the safety airbag module,
and result in serious personnel injury. Prior to
disconnecting the SAS unit connector or remove the
SAS unit, turn the ignition switch to the LOCK
position, and then remove the negative cable of
battery and wait for more than 1min to exhaust the
energy of SAS unit stored in the standby power
supply.
It is dangerous to connect with the connector of
SAS unit without tightly installed the SAS unit on
the vehicle. The impact sensor in the control module
may send the electric signal to the safety airbag
module, release the safety airbag module and cause
serious personnel injury, thus install tightly the
control module on the vehicle prior to connecting
the connector. For the assembly of the vehicles with
the single-point sensor, once the safety airbag
module released due to accident or other reasons,
the SAS unit must be replaced by a new one, even if
there were no surface damage on the used SAS unit.
The used SAS unit may have been internally
damaged and lead to abnormal operation and cause
serious personnel injury, even death. The used
single-point SAS unit is unable to carry out the
bench test or self test on the operation of lateral
safety airbag sensor. In case, where the ignition
switch is not turned off, the disconnection of the
