NEXON EV SERVICE MANUAL

SUPPLEMENTARY RESTRAINT SYSTEM (SRS) 17 1.7.2.5. 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 driver’s 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.
