Instrument Designation Usage
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

(1) The airbag controller has internal problem (DTC 93C1): when using diagnostic scan tool to test the airbag
controller, if the DTC code is 93C1, it indicates that there are problems in the controller.5-563. Trouble Identification
Trouble Record (DTC storage)
Each DTC consists of two bytes, indicating current problem or occurred problem. 93CX or 93DX indicates
current problem while 938X or 939X indicates occurred problem. Current problem can not be cancelled, even if
it is cancelled at that time, it will reoccur after initialization or a cycle of self-check. You have to make analysis
on the causes and perform troubleshooting.
The DTC is transmitted by the diagnostic scan tool instructed by ECU through the serial data interface of the
program.
