SRS airbag warning lamp inspection
1. When the ignition switch is set to the ON position, check if the SRS warning lamp remains on for 6-7 s.
2. If the SRS warning lamp shuts off after 6-7 s, this is normal.
3. Except for the items listed above, diagnostic inspection is still needed\
.
System diagnosis
Airbag ECU will initiate a series of diagnostic test cycles to check if the airbag system functions are ready for
use. This diagnostic test can guard against the restraint system's faulty execution and at the same time guarantee
prompt execution in a collision. If a malfunction appears, airbag ECU will store the appropriate trouble code and
light up the warning lamp to point out the malfunction, as to make maint\
enance more convenient.
Diagnostic interface
Troubleshooting
Basic processes of the malfunction diagnostic
There are two SRS-ECU malfunctions types classified by time: current malfunction and history malfunction.
The malfunction types categorized by property are: external malfunction \
and internal malfunction.
Current malfunction trouble codes and history malfunction trouble codes may exist at the same time. External
malfunction trouble codes can be eliminated with a diagnostic instrument, but the internal malfunction trouble
codes cannot be cleared unless the SRS-ECU is changed.
Caution: After installing a new SRS airbag system electronic control unit, the airbag system warning
lamp will remain on for 6-7 s when the ignition switch is set to the ON position. This indicates that
the SRS airbag is operating properly. At this point, the system does not need to be inspected and
repaired. Aside from this case however, the system should be diagnosed and repaired.

Malfunction judgment
1. Malfunction record (trouble code storage)
After the ECU performs the diagnostic test cycle in order to verify a malfunction, the SRS-ECU will store the
relevant code, the initial detection time, the final detection time, and the number of times it occurred in the
EEPROM.
The SRS-ECU can store 16 codes at most.

airbag ECU
Trouble code transmission is completed the SRS-ECU outputs through the maintenance program's
serial data interface to the specified diagnostic instrument (X-431 dia\
gnostic scanner).
3. Internal malfunction
The microcontroller can detect the following items not only when starting up detection, but also during the
diagnostic detection cycle.
(a) The ignition circuit triggers the transistor: The high-end transistor will be detected not only when starting up

Downloaded from www.Manualslib.com manuals search engine GWFLORID Maintenance Manual218
detection but also during the diagnostic detection cycle. However, if a short circuit on the power supply causes
a malfunction, and the low-end transistor is opened while malfunctioned, the low-end transistor can only be
detected when starting up detection, as to avoid faulty execution.
(b) Ignition voltage is provided by a pressure increase converter.
(c) Acceleration sensor performs self-detection when starting up detection.
(d) Allowed offset range of the acceleration sensor during a diagnostic cycle.
(e) Microcontroller includes AD converter, ROM, RAM, etc.
(f) Security sensor status.
Caution: There is a short-circuiting bar inside the squib circuit connector. When the connector is not
connected, the short circuit happens between the squib circuit's terminal (+) and terminal (-), as to
avoid faulty deployment caused by static electricity. When the connector is bad and the short-circuiting
bar is connected, the fault symptom may not be eliminated.
4. Clear the trouble code
When the X-431 diagnostic instrument receives the "Clear the trouble code" order sent through the serial inter-
face, the trouble code inside the ECU will be cleared. However, if an internal trouble code is recorded or has a
collision record, it will not carry out this order.
(a) Malfunction status display.
When the working voltage is supplied to the SRS-ECU through a battery, the SRS-ECU will light the warning
lamp to inspect the light bulbs. During the initialization stage, the warning lamp will remain on for 6-7 s, and
in order to inform the driver that the system has a malfunction, the warning lamp will continue to remain on
after the working voltage is supplied. If the history trouble code’s quantity is less than 16, the warning lamp
will remain lit for 6-7 s after turning the ignition on and then turn off automatically. If the history trouble code’s
quantity is 16 and the current malfunction appears, it will be recorded and the first history malfunction record
will be automatically removed.
(b) Malfunction indicator.
When the system has malfunctioned, the warning lamp will be always on.
A displayed or history malfunction can only be reset by service personnel. A SRS-ECU internal malfunction or
malfunction’s "collision record" cannot be reset. In this situation, the SRS-ECU mus\
t be replaced.
(c) Microcontroller - independent warning lamp is lit.
The controller has a self-diagnosis function. If the inner controller malfunctions, the warning lamp will always
be on.
(d) If the airbag warning lamp is always on, please inspect it according to the following steps.
The first step of inspecting any of the malfunctions is to detect the malfunction’s position with a scanner. Then
carry out the inspection using the corresponding part’s inspection method. If the scanning result is an internal
malfunction or having to do with airbag execution, the SRS-ECU can be di\
rectly replaced.
