42-2 SUPPLEMENTAL RESTRAINT SYSTEM - SUPPLEMENTAL RESTRAINT SYSTEM

HOW IT WORKS

1. Architecture
(a) . The SRS consists of steering wheel assembly, driver airbag assembly, airbag
harness assembly, clock spring and airbag ECU.
2. System self-check
(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±3V
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.
