Diagnostic detector (Hi-DS T Scan meter)
Special diagnostic meterCheck system troubles of the SRS,
and clear the DTC of ECUIII. Troubleshooting1. Basic process of trouble diagnosis
DTC of the present fault may coexist with that of the history fault.
Notice:
After the new SRS ECU is installed, the warning light of the SRS, with the ignition switch ON, will be on
for 4s and then go out permanently, indicating SRS works normal. In this case, no service is needed. Otherwise,
system diagnosis and service shall be carried out.
If with the ignition switch ON, the warning light of the SRS is not on, the relevant circuits of the warning
light shall be serviced. Then go on with the operation and enable it to work.SRS (Supplemental Restraint System)-
SRS-General Information5-55order to deploy an airbag within a certain time period after the battery
is disconnected, condenser in the ECU shall retain some electrical
energy. Otherwise, it could lead to a serious accident because of the
unexpected deployment of airbag.
6. During spray paint work, ECU, airbag assembly, clock
springassembly, etc shall be removed and kept in place to avoid the
effects of overheat. (Over 93)
7. When the SRS is serviced, a diagnostic scan meter is used to clear
the DTC to enable the normal work ofthe warning light.II. Test instrumentWarning light con-
stantly goes onuse scanner find out the troubletroubleshootingtrouble eliminated Check SRS warning light (see the right figure)
(1) Turn the ignition switch ON and find out whether the warning
light is on.
(2) 4 seconds after the process of ON-OFF, confirm that the
warning light goes out permanently.
(3) Otherwise, diagnosis and checking have to be involved in.
2. System Diagnosis
The SRS ECU will perform a series of circular diagnostic tests to check the readiness of the SRS functions.
This test can avoid unexpected explosion of the restrain system and in the same time ensure the necessary explosion
in a crash. If a trouble is detected, the SRS ECU will store a proper DTC and turn on the warning light indicating
a trouble for service.SRS Air Bag

b. Remove the connector (yellow) that connecting the lower end of the clock spring with the wire harness
of the instrument panel (see the figure below).Notice
Remove the connector of the clock spring from the wire harness of the instrument, the connector will be
short circuited automatically, which can avoid the possible serious accident resulted from the deployment of
the diver airbag assembly due to static electricity.
c. Tie two 6m plus wire harnesses for deployment to the
adaptor wire harness of the airbag, and wrap the connecting points
with insulating tape for insulation.The other ends of the wire harness
for deployment are connected to each other (short circuited). Unex-
pected deployment resulted from static electricity shall be prevented.
d. From the yellow connector of the clock spring, lead the
airbag adapter wire harnesses out of the vehicle by means of the wire
harnesses for deployment (see the figure below).
