238Section 4 Audio and Video System ReplacementI. Notice on operationPlease explain to the customer that the AM/FM broadcast channel information will be cleared when remov-
ing the battery negative terminal cable. Record the channel information before removing the negative termi-
nal cable if necessary. Reset after connecting the negative terminal cable.
yAll cassette tapes and CDs must be taken out before radio removal and installation.
yIf the cassette tapes and CDs can not be taken out due to radio fault. Do not take them out by force.
Drive the vehicle to Service Station.
yMake sure the grounding bolts are tightened before antenna removal and installation.
yThere will be noise when receiving electric wave if the grounding bolts are not tightened.

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

III. TROUBLESHOOTING1. Basic process of trouble diagnosis
yDTC of the present fault may coexist with that of the history fault.
NOTICE:
yAfter 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.
y 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.Instrument Designation Usage

250(2) Trouble indication
1In case of a trouble, the warning light will indicate. If the external trouble is a history trouble, the indication
will be cancelled. When the history trouble happens for no less than 5 times, the indicator light will remain
on even if there is no more trouble. "Low battery voltage" shall not be counted in the total number of
troubles.
2Only a service worker can reset a displayed or history trouble. The internal troubles of a SRS ECU
(HAE2.5) or the "crash record" of a trouble cannot be reset, in which case the SRS ECU (HAE2.5) shall
be replaced.
(3) Microcontroller-independent warning light on
Microcontroller with definitive troubles cannot fulfill its functions, thus cannot control the warning light. In
this case, the warning light will light up through proper circuit regardless of the microcontroller as stated
below:
yMalfunction of the battery supplying power to SRS ECU (HAE2.5): the warning lights are turned
on continuously by means of the drive function of the selfcheck light.
yLoss of internal working voltage: the warning light remains on.
yReset due to trigger failure of the watchdog: the warning light blinks.
yMicrocontroller out of work: the warning light always lights up.
yIncomplete insertion of SRS ECU (HAE2.5) connector: the warning light remains on by means of
a shorting bar.
The diagnostic procedures can well be illustrated as follows:
If it is found that the SRS warning light remains on, follow the undermentioned procedures to check even if
the light goes out eventually. First, a scan meter is used to check the location of the trouble.
Then£¬go on with the checking in accordance with specific methods and procedures for the correspondent
location.
a. If the result indicates that it is an internal trouble or that the SRS is already detonated, replace the
ECU directly.
b. Troubleshooting.

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.

255(3) Check the wire harness between the fuse box and the connector of the SRS unit
CAUTION
If it is not handled properly, the airbag assembly may be triggered and deployed, leading to serious injury to a
person. Therefore, prior to handling, read the service cautions carefully. See service cautions for SRS.
1Turn the ignition switch to LOCK.
2Loosen the negative (-) terminal cable from the battery and wait for over 1 minute.

4Loosen the connector of the clock spring.
5Remove glove box (along with passenger airbag assembly)
6Loosen passenger airbag assembly connectors.
7Remove left trim plate.
8Loosen all the SRS unit connectors.
9Reconnect the negative (-) terminal cable of the battery and turn ignition switch ON, check whether the
electrical potential between pins 5 and 6 (ground) of the connector of SRS unit is higher than 9V.
Yes: continue with next step.
No: replace the wire harness.
VTurn the ignition switch to LOCK. 11 Loosen the negative (-) terminal cable from the battery and wait for over 1 minute. 12 Remove left trim plate. 13 Disconnect the adaptor connector of SRS unit. 14 Reconnect the battery negative (-) terminal cable and turn the ignition switch ON, check whether the
voltage between the corresponding pin of the connector and the pin (ground) is higher than 9V.
Yes: completion of trouble diagnosis.
No: replace the wire harness.
