SUPPLEMENTAL RESTRAINT SYSTEM - SUPPLEMENTAL RESTRAINT SYSTEM 62-3

HOW IT WORKS

1 . Architecture
(a) The SRS consists of steering wheel assembly, driver airbag assembly, front passenger
airbag assembly, airbag harness assembly, clock spring and airbag ECU.
2 . System Self-check
62
(a) When switching the ignition to “ON”, the SRS is started and the airbag ECU performs
self-check as preset.
• If the airbag indicator lamp lights up and then goes out in 4 seconds, it means
that the system runs correctly and passes the self-check. Then the RCM start
to monitoring.
• If the airbag indicator lamp doesn't light up, flashes or stays on, it means that
the system encounters trouble and fails in the self-check.
Operating temperature: -35 ~ 85℃

Operating voltage: 12 ± 3 V

3 . How It Works
(a) When driving under a normal situation (including all kinds of traffic conditions and
events), as long as there is no ignition command from the airbag ECU, the drive airbag
stays undeployed.
(b) When serious head-on collision happens, the airbag ECU will send the ignition signal
immediately to deploy the driver airbag.
(c) The deployed airbag diverts part of the impact from the driver, in order to minimize the
possible injury and provide protection.

DANGER

• The airbag is designed to provide further protection in addition to the seat belt.
However, it is in no way a replacement of the latter.The seat belt must be properly
fastened during the drive. Otherwise, quickly inflated and deployed, the airbag
may lead to worse injury instead of desired protection.
• To achieve desirable protection, the driver must fasten his seat belt correctly
and keep a good posture.
• It is important to use the matching driver airbag assembly and airbag ECU. Do
not combine it with the products of other manufacturers.

WARNING

• It is important to visit a Foton authorized workshop with certified technicians
for services.
• Never use an analog multimeter to measure the resistance of the airbag, or it
may be deployed unexpectedly.
