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

2454. Trouble Identification
(1) Trouble Record (DTC storage)
When the circular diagnostic tests are involved in identification of a trouble, the SRS ECU (HAE2.5) will
store relevant codes, first/last diagnosis time and frequency of the trouble in EEPROM.
ySRS ECU (HAE2.5) can store up to 6 troubles, low voltage trouble as well as two crash records (front
and side).
yThe transmit of the DTCs are carried out in the way that the SRS ECU£¨HAE2.5£©via serial data
interface of the maintenance procedures assign the codes to the diagnostic detector.No. Trouble De scription Trouble shooting

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
