2435. 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.1 1 D AB Lo D r iv er a ir b ag , lo w p o s it io n

251Section 2 TroubleshootingI. LIST OF TROUBLES1. SRS warning light OFFDIAGNOSTIC PROCEDURESWhen performing the first diagnostic check, it is advised to shake slightly the harness and connector to see if
there is any discontinuous poor contact in circuit. If there is such a problem, make sure that the connections
of the connector, terminals and wire harness are correct and undamaged. Otherwise, follow these procedures:
(1) Check other wire harnesses and instrument cluster indicator lights
1Turn the ignition switch ON.
2Any other light on?
Yes: turn the ignition switch to LOCK, and continue with the next step.
No: check the power supply and ground system (fuse) of the instrument cluster, and continue with step 5.
(2) Check light bulb
CAUTION:
Mishandling of SRS components may release unexpectedly airbag and seat belt pretensioner, probably lead-
ing to a serious accident. Read the service cautions before handling a SRS component.
1Turn the ignition switch to LOCK.
2Disconnect the negative (-) terminal cable from the battery and wait for at least 60s.
3Remove the instrument cluster.
4Measure and see if the two pins of the SRS warning light is triggered.
Yes: continue with next step.
No: replace the bulb of the warning light.

and find out the causes of the trouble. If the communication fails, continue with the following procedures:
(1) Check battery
1Check battery voltage.
2Is voltage higher than 9V?
Yes: continue with next step.
No: Insufficient battery supply. Check the charging/discharging system, and then continue with step (5).
(2) Check the continuity of the wire harness between ECU and instrument cluster
1Turn the ignition switch to LOCK.
2Disconnect negative (-) terminal cable from the battery.
3Open the guard plate of the central passage.
4Disconnect the connector of the instrument cluster.
5Connect the negative (-) terminal cable of the battery.
