DIAGNOSIS-SUPPLEMENTAL INFLATABLE RESTRAINT SYSTEM (SRS) 62-1
SUPPLEMENTAL INFLATABLE RESTRAINT SYSTEM

(SRS)

NOTICES

62
1. This type of vehicle is configured with the SRS system. In case of operation not
following the correct steps, it may cause sudden expansion of SRS, and even result
in serious accidents. At the same time, in case of wrong operation for the SRS
system, it may also lead to the failure to work properly.
2. Always confirm to turn off ignition switch to "LOCK" position, and don't carry out the
operation until 90s after disconnecting the battery positive and negative cable. (The
supplemental restraint system is configured with a backup power supply, therefore
if the operation is carried out within 90s after disconnecting the battery positive and
negative cable, it may cause the sudden expansion of SRS.)
3. Never make the horn button assembly exposed in the hot air or open fire.
4. Because it is hard to identify the symptom for the SRS system, diagnostic trouble
code (DTC) will be taken as the most information source when troubleshooting.
Therefore, during troubleshooting for the SRS system, always detect the diagnostic
trouble code (DTC) before disconnecting the battery.
5. Even if the impact is very small and the airbag assembly is not expanded, the horn
button assembly and air bag ECM shall also be checked.
6. If it may have an impact on the SRS control module ECM at the time of
maintenance, always disconnect SRS control module ECM connector firstly.
7. Never use the SRS system parts and components removed from another vehicle. If
the replacement is needed, always use the new parts and components.
8. Never disassemble horn button assembly.
9. If the horn button assembly falls to the ground, or cracks, pits, or other defects
appear on the shell, always replace it with the new parts and components.
10. A high-impedance multimeter shall be used for the system circuit fault check.
11. The parts and components of the SRS system carry the explanatory information
labels, and always follow the precautions on the label in the process of
maintenance.
12. Always check the SRS indicator light after completing the operation of the SRS
system.
13. After disconnecting the battery negative cable, the memory of electronic clock
and audio system will be cleared. All necessary data shall be recorded before
maintenance. At the end of maintenance, reset the audio system and adjust the
electronic clock. Never try to use the backup power supply outside of the vehicle, so
as to avoid the loss of data in each memory of system. The backup power supply
will supply power for the SRS system, it may cause a sudden expansion of SRS at
the time of maintenance.
