SUPPLEMENTARY RESTRAINT SYSTEM (SRS) 28 V 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 crash sensor. It also provides the electrical continuity for airbag, horn, vehicle cruise control and infotainment system. The clock spring needs to be replaced 1. 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. 2. If any connector or internal routing of wire/s are damaged or disconnected 3. Intermittent signal continuity between input and output of clock spring LOCATION It is mounted on the steering column along with the Combi-switch. CONNECTOR BOTTOM SIDE CONNECTOR TOP SIDE CONNECTOR
