Diagnose 

 

Inspection of SRS diagnostic system 

When the SRS is powered on, airbag SDM will turn on warning light and start a self-checking, 
during which the warning light will flash for 6 seconds with a frequency of 1Hz. Any fault 
detected by SDM will activate airbag warning light, and the fault will be stored to SDM 
memory. SDM will check SRS fault each time it is powered on. A fault will be marked by 
SDM if it is detected consecutively for five times. A fault diagnosis testing cycle lasts for 400 
ms, therefore it takes SDM 2 seconds (400ms X 5 times) to confirm a fault. If a marked fault 
continues, the warning light will keep on, this is called a “current fault”. If a marked fault 
does not appear in the following 25 consecutive testing cycle (400ms X 25 = 10 seconds), it 
will be unmarked, this is called a “historical fault”. 

Diagnose with Diagnostic tester 

Diagnostic tester reads data in SDM memory for continuous data communication. A 
diagnostic tester is able to read fault code in memory and clear part of stored data after 
maintenance, but is unable to clear internal faults such as collision record and arithmetic data 
fault. 

To properly operate the diagnostic tester, first turn off ignition switch, and connect diagnostic 
tester with OBDII connector, then turn on ignition switch. Next steps please refer to 
instruction manual of diagnostic tester.

Maintenance and Service of SRS System

 

Warning:  

In case engine is stopped and fuse is taken off, the SDM will provides sufficient voltage for 1 
minute to activate airbag. If airbag is still connected, do not start maintenance operation 
within one minute after power supply to SDM is switched off. If airbag is disconnected, the 
maintenance may be started right away without waiting for 1 minute to be discharged. Any 
failure in temporary disconnection of SRS during maintenance will result in mistrigger of 
airbag, personal injuries and critical SRS damages.

2.  Turn ignition switch to locked position and take out the key 
3.  Take out airbag fuse from fuse box and wait for at least 1 minute to discharge SDM 

capacitor

Connecting Airbag 
1.  Insert airbag fuse into fuse box 
2.  Turn ignition switch to on position, airbag indicator light will be turned on for 6 seconds 

and then goes out. If the indicator light does not work in accordance with the foregoing, 
please refer to “Check with SRS Diagnostic System” part of this manual. 

Warning: Keep away from airbag when turning on ignition switch to avoid personal injuries. 

 
Operation, Installation and Diagnosis 

 Airbag shall not be placed in ambient temperatures higher than 65ºC (149ºF) 
 After falling from a height of 0.9 meter (3 feet) or higher, the airbag and SDM shall not 

be used again. 

 When replacing SDM, the arrow on SDM shall always point to forward direction of 

vehicle. 

 SDM must be installed horizontally on the installing surface, and must be parallel to 

vehicle body coordinate axes. 

 To avoid diagnostic fault code, do not supply power to airbag before all system 

components are properly connected. Or the airbag shall be powered in accordance with 
special requirements of diagnostic tester if any. 

 Any SRS system diagnosis must be started with SRS diagnostic system. SRS diagnostic 

system inspection will check for correct indicating functions and select correct method to 
diagnose any SRS fault. Omission of this step may result in longer diagnostic hours or 
inaccurate part replacement. 

 
Repair and Check after Accident 

Warning: any repair of vehicle structure shall resume the original shape. For triggered airbag, 
SDM and airbag shall be replaced with measurement of steering post dimension. 

 Any damaged SRS part or mount point must be replaced. 
 Never use SRS parts from other vehicles (except new SRS parts from the vehicle of the 

same model). 

 Do not try to repair hairspring, airbag and safety belts. Should any defect be found, these 

parts must be replaced. 

Check replaced SRS part number or marks. Airbag gas generator with the same look may 
have a different internal structure. 

 
Replacing Airbag Parts after Activation in Accident 
All SRS parts must be replaced after airbag is activated in a collision accident. Powder-like 
residue may be found on airbag surface after activation, which may include cereal starch and 
products of chemical reaction (used to lubricate airbag when inflating).
