SUPPLEMENTARY RESTRAINT SYSTEM (SRS)

11.1.6.2.5. CLOCK SPRING
Clock spring is a spirally wound wire coil (not a slip
ring) mounted to steering column. This single-wire
type contact reel (clock spring) design ensures
most reliable contact possible between air bag
module assembly and SRS ECU. It also provides
the electrical continuity for airbag, horn, vehicle
cruise control and infotainment system.
The clock spring only needs to be replaced when
the connectors that attach to the drivers airbag is
melted and fused directly to the DAB module.
During a deployment the gas conversion creates a
heat exchange inside the DAB module and that
causes connectors to melt.
LOCATION
It is mounted on the steering column along with the
Combi-switch.
