5. Servicing operation shall be carried out 60s after the negative

(-) terminal cable is disconnected from the battery. In addition,

the disconnected negative (-) terminal cable shall be protected

with insulating tape for insulation.

In order 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 spring

assembly, etc shall be removed and kept in place to avoid the effects of overheat. (Over 93¡æ)

7. When the SRS is serviced, a diagnostic scan meter is used to clear the DTC to enable the normal work of

the warning light.

II. TEST INSTRUMENTS

III. TROUBLESHOOTING

1. 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 6s 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.

2. Check SRS warning light

(1) Turn the ignition switch ON and find out whether the warning light is on.

(2) Six 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.

3. System Diagnosis

The SRS ECU (HAE2.5) 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 (HAE2.5) will store a proper DTC and

turn on the warning light indicating a trouble for service.
