the SRS airbag system status. 

 

 

PAB front passenger airbag module, located under the instrument panel in front 
of the front passenger, for protecting the front passenger by popping in case of 
front impact

  

 

DAB driver airbag module, located in the middle of the instrument panel, for 
protecting the driver by popping in case of front impact

 

SAB front side airbag modules, located inside the driver seat and the front 
passenger seat, for protecting the driver and the front passenger by popping in 
case of side impact

 

 

CAB side air curtain modules, located below the ceiling above the left and right 
side wall, for protecting the front and rear occupants’ heads by popping out the 
airbag in case of side impact

 

 

     

 

CLOCK SPRING, located below the steering wheel, for connecting the DFAB, 
horn, steering wheel button and so on to the main harness

 

 

   

 

Airbag ECU, located at the central passage below the instrument panel, for 
controlling the ignition of the airbag system and testing the entire system status

 

Front Impact Sensor. Vehicle body front portion in the middle part, for acquiring 
X-direction acceleration signal. 

Side Impact Sensor. Located in the lower B-pillar body, so each one for 
collecting Y direction of the acceleration signal. 

Airbag Fault Check 

After the ignition switch is turned from OFF to ON (hereinafter referred to as turning on the 
power switch), the airbag fault indicator lamp flickers 6 times and then goes out without 
coming on again, indicating the airbag system is normal, which requires no maintenance to 
the airbag system.  

If the airbag status indicator lamp does not come on, or is always on or is flashing, after the 
power switch is turned on, it is indicated there is fault in the airbag system, which requires 
maintenance to the airbag system.

Warning for Maintenance 

About the component disassembly 

The disassembly and re-assembly of the airbag 
system parts may result in the system failure and 
possibly cause serious injury or even death in case 
of an accident; therefore, do not disassemble any 
part of the airbag system. 

 

About the harness maintenance 

The incorrect maintenance to the wiring harness of 

the airbag system may accidentally release the 
airbags or the seat belt pretensioners, causing 
serious injury. If there is system harness fault, you 
should replace the harness instead of repairing it.  

 

About checking the airbag module 

Checking the airbag module with ohmmeter may 
make the airbag release, causing serious personal 
injury; therefore, do not use an ohmmeter to check 
the airbag module and you should use the OBD 
system to diagnose the airbag system failure. 

 

About operating the airbag module 

Handling the unreleased airbag in operating 
condition may make the airbag released 
unexpectedly, causing serious injury. When 
handling the unreleased airbag in operating 
condition, be sure to make its front surface towards 
outside, so as to reduce the possibility of injury 
when the airbag is released. 

 

It is dangerous to place the unreleased airbag 
module facing downward. If the airbag module is 
released, the airbag movement may result in 
serious personal injury; therefore, you should place 

 

Airbags and Restraint System 3B-25 

 

the front surface facing upward, so as to reduce the 
range of motion in case of the unexpected release 
of the airbag. 

 

About operating the side airbag module 

When the side airbag module is released against 
impact, the interior backing and skeleton of the 
seat back may be damaged. If the seat back is to be 
reused, the side airbag module is properly not able 
to be released normally, resulting in a serious 
accident; therefore, if the side airbag module is 
released, the side airbag module and also the 
backing, skeleton and trim plate of the seat back 
must be replaced with new parts. After 
maintenance, please make sure the seat is correctly 
installed and fixed. 

About operating the SAS unit 

With the ignition switch not turned off, 
disconnecting the SAS unit connector or removing 
the SAS unit may make the airbag module released, 
causing serious personal injury. Before the SAS 
unit connector is disconnected or the SAS unit is 
removed, turn the ignition switch to the LOCK 
position, and then remove the negative cable of the 
battery and wait for over 1min. to have the SAS 
unit standby power exhausted.  

It is very dangerous to connect the SAS unit 
connector if the SAS unit is insecurely installed on 
the vehicle, because the crash sensor in the control 
module may deliver the electrical signal to the 
airbag module to make the airbag module released, 
resulting in serious personal injury; therefore, 
please have the control module securely installed 
on the vehicle before connecting the connector. 

For the vehicle equipped with a single-point sensor, 
once the airbag module is released due to an 
accident or other reasons, the SAS unit must be 
replaced with a new one, even if the surface of the 
used SAS is without damage. The used SAS unit 
may have internal damage that may cause 
abnormal operation, resulting in serious injury or 
even death. The used single-point SAS unit should 
not be subject to the bench test. Self-check the 
operation of the airbag sensor.  

With the ignition switch not turned off, 
disconnecting the side airbag sensor connector or 
removing the side airbag sensor may make the side 

airbag sensor operating and then the side airbag 
module released, causing serious personal injury. 
Before the side airbag sensor connector is 
disconnected or the side airbag sensor is removed, 
turn the ignition switch to the LOCK position, and 
then remove the negative cable of the battery and 
wait for over 1min to have the SAS control module 
standby power exhausted. 

Don’t make the side airbag sensor subject to 
vibration or have the sensor disassembled, for that 
may make the side airbag module released 
unexpectedly, causing personal injury or serious 
accident due to abnormal operation. The sensor is 
integrated in the side airbag module; the module 
may have problem, such as internal fault, after the 
side airbag module is released. Even though there 
is no outside damage or distortion, adopting the 
used side airbag sensor shall make the side airbag 
module unable to operate normally, causing 
serious personal injury; therefore, please replace 
the used sensor with a new one. The side airbag 
sensor should be not subject to bench test. Self-
check the pretensioner seat belt.  

Checking the pretensioner seat belt with ohmmeter 
may make the airbag release, causing serious 
personal injury; therefore, do not use an ohmmeter 
to check the pretensioner seat belt and you should 
use the OBD system to diagnose the pretensioner 
seat belt failure.

 

 

About operating the parts 

Prevent the parts from being contaminated with 
water, oil or grease, or else the airbag module and 
the pretensioner seat belt cannot be released and 
expanded, causing serious personal injury. Using a 
screwdriver, etc. into the airbag module connector 
or the pretensioner seat belt may make the 
connector damaged and the airbag module or the 
seat belt pretensioner released abnormally, causing 
serious injury; therefore, don’t insert any foreign 
object into the connector. 

 

Airbags and Restraint System 3B-26 

 

 

About reusing parts  

Even if the airbag module or pretensioner seat belt 
is not released in the collision, and its surface is 
not damaged, the interior may have been damaged, 
causing incorrect operation that may result in 
serious personal injury. Therefore, self-check the 
undamaged airbag module or pretensioner seat belt 
to determine whether it is reusable or not.
