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.

Possible
causes
• Voltage disappears (fuse open circuit)
• Combination meter malfunction
• Wire harness malfunction between the instrument cluster and ECU unit
Diagnostic procedures
While performing the first malfunction detection, it is suggested to wiggle the wire harness and plugs to check for
intermittent or poor contact. If there is, please check whether the plugs, terminals, and the wire harness are connected
properly and undamaged. If the above mentioned problems do not exist, pl\
ease take the following steps.
StepsInspectionOperation
1
Detect other wire harness and instrument cluster indicator
lamps
• Set the ignition switch to the ON position
• Are other warning and indicator lamps on?
Yes
Set the ignition switch to the LOCK
position, and then proceed to the
next step
No
Detect the instrument cluster's
power supply system and the
grounded system (fuse)
2
Inspect the light bulbs
Warning:
Incorrect airbag system component operation will cause the
airbag and preload seat belt to opened accidentally, which
may cause serious injuries. Please read the airbag system
services warning before working on the airbag components
• Set the ignition switch to the LOCK position
• Disconnect the battery's negative cable and maintain for at
least 60 s
• Remove the combination meter
• Check whether the two corresponding pins of the airbag
warning lamp are conducting
Yes
Go to the next step
No
Replace the combination meter
3
Detect the wire harness connection between the ECU unit and
the instrument cluster
• Set the ignition switch to the LOCK position
• Disconnect the battery's negative cable
• Disconnect the instrument cluster plugs
• Check whether the warning lamp's corresponding circuits
are conducting
YesGo to the next step
No
Replace the wire harness
