SUPPLEMENTARY RESTRAINT SYSTEM

DESCRIPTION AND OPERATION

DCU monitoring

When the ignition switch is turned to position ’II’, the
DCU monitors the readiness of the SRS components
during the power-up phase and continues monitoring
during the complete ignition cycle. The DCU monitors
the status of the following components:

•

Accelerometers

•

Safing sensor

•

Microprocessor

•

Front airbags

•

Side airbags (from 99MY)

•

Seatbelt pre-tensioners (from 99MY)

•

Front crash sensors (distributed systems
only)

•

SRS warning lamps

If a system or component fault is detected, the SRS
lamps are illuminated.

Power supply and back-up

The ignition power feed provides a positive voltage
supply to the SRS DCU and the SRS warning lamps
via a dedicated system fuse located in the engine
compartment fusebox. In the event of power supply
failure, check the condition of the fuse and the
connection between the Main and Fascia harnesses
located on the lower right hand side ’A’ post.

The DCU incorporates capacitors which store enough
electrical charge to ensure the system will continue to
function for a short period of time in the event that the
normal power supply is disconnected during a
collision. If the power supply is disconnected, the
capacitors store enough charge to enable operation of
the triggering device and firing circuitry.
