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

247(2) Internal troubles
The micro controller can check the following items not
only in the initiation check but also in the circular diagnos-
tic check.
1Trigger transistor of ignition circuit: high-end transistor
can be checked not only in the initiation check but
also in the circular diagnostic check. However, since
the low-end transistor is open when connected in short
circuit to power source, it can only be checked in the
initiation check to avoid explosion.
2The ignition voltage is provided by supercharge
converter.
3The acceleration sensor performs selfcheck in the
initiation check.
4Range of allowed deviation of acceleration sensor in the circular diagnostic check.
5Microcontroller includes AD converter, ROM, RAM, etc.
6Status of safety sensor.NOTICE
The connectors of the squib circuit contain a
shorting bar. When the connector is not
connected, the unexpected deployment is
caused by the short in the circuit arising from
the contact of the positive (+) and negative (-)
terminals or the static electricity. If there is
poor connection for connectors, the symptom
may not be removed even when the shorting
bar is connected.14Ignition c irc uit 4 (passe nger se a t be lt pre tensione r), low re sistanc e

248An external watchdog can check the operation situation of the microcontroller. The failure of the microcontroller
can trigger the watchdog, which in turn can reset the microcontroller and turn on the warning light.No. List of Trouble s Trouble De sc ription

249(3) Clear DTCs
When ECU diagnostic tester (Hi-DSTM) receives the "Clear DTCs" command from the serial interface,
the DTCs stored in ECU will be cleared off. But if an internal DTC is recorded or there is one crash
record, the command will not be executed.
5. Trouble display (Warning light ON)
(1) Light bulb check
When working voltage is supplied to SRS ECU (HAE2.5) through battery, SRS ECU (HAE2.5) lights up
the warning light to check the light bulb. In the initiation stage, the light will be on for 6s at the frequency
of 1Hz and then go out. To give notice of the presence of troubles to the driver, the warning light will
remain on after the working voltage is supplied. If the history troubles happened for less than 5 times, the
warning light will be on for 6s after ignition on and then go out. In the initiation stage, the SRS ECU
(HAE2.5) will not check crash and arrest deployment until the circuit of SRS ECU (HAE2.5) goes
stable.
Thus, after ignition on, the display mode of the warning light is one of the following states displayed in the
initiation stage:
STATE 1) The warning light will remain on if there is crash record or the history records of the trouble
are no less than 5 times. Meanwhile, the warning light will remain on if there is explosion trouble.
STATE 2) The history troubles are no less 1 time but less than 5.
("Low battery voltage" shall be excluded from the total number of the troubles.))
STATE 3) Normal (i.e. there is no explosion trouble or history trouble.))

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.
